Nothing ruins a good gaming session faster than frame drops, delayed controls, screen stuttering, and a PC that sounds like it is preparing for take-off. The good news is that weak hardware does not always mean unplayable performance. With the right settings, you can increase FPS in games on a low-end PC without immediately buying a new graphics card or replacing the entire system.
The biggest improvements usually come from reducing unnecessary graphical effects, choosing a realistic resolution, closing background programs, updating drivers, and preventing the processor or graphics chip from overheating. You may not turn an entry-level laptop into a high-end gaming machine, but you can often make games feel noticeably smoother and more responsive.
This guide covers beginner-friendly changes first, followed by more advanced low-end PC gaming optimisation methods for players who want to squeeze every usable frame from their hardware.
What Is FPS, and Why Does It Matter?
FPS stands for frames per second. It measures how many individual images your computer renders every second while a game is running.
A higher frame rate generally produces smoother movement and more responsive controls:
- Below 20 FPS: Usually feels slow and uncomfortable
- Around 30 FPS: Playable for many slower single-player games
- Around 45 FPS: A good target for weaker computers
- 60 FPS: Smooth for most types of gaming
- Above 60 FPS: Most useful on high-refresh-rate monitors
Average FPS is not the only measurement that matters. Frame consistency is equally important. A game that constantly moves between 25 and 60 FPS can feel worse than one locked at a steady 35 or 40 FPS.
This is why optimisation should focus on stable performance rather than chasing the highest number possible.
Before changing anything, learn how to check PC specifications so you know which component is limiting your system. The most important specifications are:
- Processor model
- Graphics card or integrated graphics model
- Installed RAM
- Storage type
- Monitor resolution and refresh rate
How to Increase FPS in Games on a Low-End PC
Start with the changes that provide the greatest performance gain for the least effort:
- Lower the rendering resolution.
- Reduce shadows, reflections, anti-aliasing, and volumetric effects.
- Close browsers, launchers, recording programs, and unnecessary background apps.
- Update the correct graphics driver.
- Use Windows Game Mode and a performance-focused power setting.
- Check CPU and GPU temperatures.
- Set a realistic frame-rate cap.
Do not change twenty settings at once. Adjust one group of options, test the game, and record the result. This makes it easier to identify which changes actually help.
You can use the game’s built-in FPS counter, Steam’s performance overlay, the NVIDIA App, AMD Software, or MSI Afterburner to monitor frame rates and hardware usage.
Best FPS Settings for Low-End PC Gaming
Graphics presets are convenient, but they are rarely ideal. Selecting “Low” may disable effects that barely affect performance while leaving another demanding setting enabled.
A better approach is to adjust each option manually.
Low, Medium, and High Settings Explained
Low settings reduce graphical detail and processing load. They usually provide the highest FPS but may produce blurry textures, flat lighting, short object-view distances, and rough edges.
Medium settings balance image quality and performance. Medium is often the best starting point when a game already runs near your target frame rate.
High settings improve visual detail, lighting, shadows, reflections, and environmental effects. They can place heavy pressure on the GPU and sometimes the CPU.
For a low-end computer, use Low as the base preset. Raise individual settings only when they have little effect on performance.
Recommended Starting Settings
| Graphics option | Recommended setting | Performance impact |
| Resolution | 1280 × 720 or 1600 × 900 | Very high |
| Render scale | 70%–90% | Very high |
| Shadows | Low or Off | High |
| Reflections | Low or Off | High |
| Volumetric effects | Low or Off | High |
| Ambient occlusion | Off | Medium to high |
| Anti-aliasing | FXAA, TAA Low, or Off | Medium |
| Textures | Low or Medium | Depends on available graphics memory |
| View distance | Low or Medium | Can affect CPU and GPU |
| Effects quality | Low | Medium |
| Motion blur | Off | Usually small FPS effect |
| Depth of field | Off | Low to medium |
| Film grain | Off | Usually visual preference |
| Ray tracing | Off | Extremely high |
| V-Sync | Test On and Off | Depends on system |
| FPS limit | 30, 40, 45, or 60 | Improves consistency |
Which Settings Should You Lower First?
Reduce these options first:
1. Shadows
Shadows are among the most expensive graphics settings. High-quality shadows require the computer to calculate additional lighting information, higher shadow-map resolutions, and more detailed edges.
Set shadows to Low before disabling them completely. Low shadows often preserve enough depth while providing a useful performance gain.
2. Volumetric Lighting, Fog, and Clouds
Volumetric effects create realistic light rays, smoke, fog, and cloud density. They can be extremely demanding in open-world, survival, and racing games.
Use Low or Off on integrated graphics.
3. Reflections
Screen-space reflections and high-quality water reflections consume substantial GPU resources. Lower them before reducing texture quality.
4. Ambient Occlusion
Ambient occlusion adds subtle shadows where objects meet. It makes scenes look more realistic, but it is not essential for gameplay.
Disabling SSAO, HBAO, or similar options can improve performance on older graphics cards.
5. Anti-Aliasing
Anti-aliasing reduces jagged edges. MSAA can be particularly expensive, while FXAA is normally lighter but may make the image appear softer.
For a low-end system, try:
- FXAA
- Low TAA
- SMAA Low
- No anti-aliasing
Avoid high MSAA levels unless the game is already running comfortably.
Do Not Automatically Set Textures to the Lowest Level
Texture quality primarily affects graphics-memory use. A dedicated GPU with enough VRAM may handle Medium textures without a major FPS penalty.
However, exceeding available graphics memory can cause:
- Sudden stuttering
- Delayed texture loading
- Objects turning blurry
- Long pauses when entering new areas
- Heavy storage activity
Start with Low textures on integrated graphics or GPUs with very limited VRAM. Test Medium if memory usage remains within a safe range.
How Should You Balance Resolution and FPS?
Resolution controls how many pixels the GPU must render. Reducing it is one of the fastest ways to improve gaming performance on a PC with weak graphics hardware.
For example:
- 1920 × 1080 contains about 2.07 million pixels.
- 1600 × 900 contains about 1.44 million pixels.
- 1280 × 720 contains about 0.92 million pixels.
Rendering at 720p therefore gives the GPU much less work than rendering at 1080p. The image will look softer, especially on a large screen, but the FPS improvement can be substantial when the GPU is the main bottleneck.
Try this order:
- Keep the monitor at its native desktop resolution.
- Set the game to 1600 × 900.
- Test performance in a demanding area.
- Drop to 1280 × 720 when necessary.
- Use resolution scaling or upscaling if the game supports it.
Use Render Scale Before Dropping the Display Resolution
A render-scale setting allows the interface to remain sharp while the 3D scene renders at a lower internal resolution.
At 1080p:
- 100% renders at full 1080p.
- 85% lowers the internal resolution moderately.
- 75% provides a larger FPS improvement.
- 50% may look noticeably blurry.
Start at 85%. Lower it in small steps until the frame rate becomes acceptable.
Use FSR, XeSS, or DLSS When Available
Modern upscaling technologies render the game below the selected output resolution and reconstruct the image. Compatibility depends on the game and hardware.
For a weak PC, test modes in this order:
- Quality
- Balanced
- Performance
- Ultra Performance only as a last resort
Quality mode usually preserves the clearest image. Performance mode can provide more frames but may introduce blur, shimmering, or unstable fine details.
Fullscreen or Borderless Windowed?
Exclusive fullscreen historically produced the most predictable performance, but modern Windows versions have improved windowed and borderless presentation.
Windows 11 includes Optimizations for windowed games for compatible DirectX 10 and DirectX 11 titles. The feature uses a newer presentation model that can reduce frame latency and support technologies such as variable refresh rate.
Test both fullscreen and borderless modes. Keep whichever delivers better frame pacing on your specific system.
How to Boost FPS on a Low-End PC Through Windows Settings
A game has to share processor time, RAM, storage bandwidth, and network activity with Windows and every program running in the background.
Reducing unnecessary background load can improve both FPS and stuttering.
Enable Game Mode
Open:
Settings > Gaming > Game Mode
Turn Game Mode on.
Game Mode is not a replacement for proper graphics settings, but it can reduce interference from background activity while a game is running. Keep it enabled unless a particular game performs worse during testing.
Select Best Performance Power Mode
On a laptop or desktop running a recent version of Windows:
- Open Settings.
- Select System.
- Open Power & battery.
- Find Power mode.
- Choose Best performance.
Laptop users should play while connected to the original charger. Many laptops reduce CPU and GPU power when running on battery.
Higher performance modes can increase power consumption, temperature, and fan noise. Monitor temperatures after making the change.
Disable Unnecessary Startup Apps
Open Task Manager with Ctrl + Shift + Esc, select Startup apps, and disable programs that do not need to launch with Windows.
Common examples include:
- Chat applications
- Cloud-sync clients
- RGB-control software
- Printer utilities
- Multiple game launchers
- Automatic update assistants
- Music applications
- Manufacturer utilities you do not use
Do not disable security tools, audio drivers, touchpad software, or hardware services unless you understand their purpose.
For a broader walkthrough, create an internal guide covering Windows gaming optimisation settings.
Close Background Programs Before Playing
Web browsers can consume significant RAM, particularly when many tabs are open. Streaming video, screen recording, file syncing, virus scans, and software updates can also create CPU, storage, or network activity.
Before launching a demanding game, close:
- Chrome, Edge, or Firefox tabs
- Discord streams
- OBS or other recording tools
- Adobe applications
- Cloud backups
- Torrent clients
- Unused launchers
- Large downloads
- Virtual machines
Keep voice chat open when you need it, but disable unnecessary overlays and animated interface features.
Disable Overlays You Do Not Use
Overlays are convenient, but running several simultaneously can cause conflicts or small performance losses.
Check:
- Xbox Game Bar overlay
- Steam overlay
- Discord overlay
- NVIDIA overlay
- AMD overlay
- Third-party monitoring overlays
Keep the one or two features you actually use. Disable the rest, especially when troubleshooting stuttering or crashes.
Reduce Windows Visual Effects
Search Windows for “Adjust the appearance and performance of Windows.”
Select:
- Adjust for best performance
Alternatively, disable only animations, fading effects, transparency, and window shadows while keeping readable fonts enabled.
This usually produces a modest improvement rather than a dramatic FPS increase, but it can make an older system feel more responsive.
GPU and CPU Optimisation Tips
The GPU creates the visual frame, while the CPU handles game logic, physics, artificial intelligence, draw calls, and many background tasks.
Which component limits FPS depends on the game and settings.
How to Identify a GPU Bottleneck
You are probably GPU-limited when:
- GPU usage stays near its maximum.
- Lowering resolution increases FPS.
- Reducing shadows or effects improves performance.
- CPU usage is not unusually high.
- Graphics settings strongly affect the result.
In this situation, lower resolution and GPU-heavy effects.
How to Identify a CPU Bottleneck
You may be CPU-limited when:
- Lowering resolution barely changes FPS.
- One or more CPU cores remain heavily loaded.
- GPU usage stays well below maximum.
- Performance drops in crowded areas.
- Large multiplayer matches run worse than quiet maps.
- Increasing view distance or crowd density reduces FPS.
In this situation, lower:
- View distance
- Crowd density
- Physics quality
- Simulation quality
- Traffic density
- Destruction detail
- Number of visible objects

Update Your Graphics Driver
Graphics drivers include compatibility updates, game-specific profiles, stability improvements, and support for newer software features. Download them only from the graphics manufacturer or your laptop manufacturer when an OEM-specific driver is required.
NVIDIA users can download current supported drivers from the official NVIDIA GeForce driver page.
AMD users can install drivers and manage compatible graphics features through AMD Software: Adrenalin Edition.
Players using Intel integrated or dedicated graphics can identify compatible updates with the Intel Driver & Support Assistant.
Create a dedicated internal tutorial on how to update graphics drivers safely.
Do not assume every new driver will improve an old game. If a game becomes unstable after an update, reinstall the driver cleanly or return to a known stable version supported by your hardware.
Keep Temperatures Under Control
Heat can reduce performance when a processor or graphics chip reaches its thermal limits and lowers its operating speed.
Warning signs include:
- FPS starts normally and falls after several minutes.
- Clock speeds decrease as temperatures rise.
- Laptop fans run at maximum speed.
- The keyboard or case becomes unusually hot.
- Games stutter more during long sessions.
Basic fixes include:
- Clean dust from air vents.
- Place a laptop on a hard, flat surface.
- Do not play on a bed, blanket, or cushion.
- Improve airflow around the case.
- Check whether fans are spinning correctly.
- Replace old thermal paste only when you understand the procedure.
- Use a cooling pad when the laptop’s intake design benefits from one.
Link readers to a gaming laptop cooling guide or safe PC temperature guide for detailed instructions.
Should You Overclock a Low-End PC?
Overclocking can provide a small performance gain, but it should not be the first step. Poor cooling, weak power delivery, and laptop restrictions can make overclocking ineffective or unsafe.
Before changing clock speeds:
- Record temperatures and FPS at default settings.
- Change only one value at a time.
- Use small adjustments.
- Run a stability test.
- Stop when temperatures, crashes, or visual corruption increase.
Beginners should use monitoring features first and leave voltage controls untouched.
How to Improve RAM Usage for Gaming
Low RAM does not always reduce average FPS directly, but insufficient memory can create severe stuttering as Windows moves data between RAM and storage.
How Much RAM Is Enough?
Requirements vary by game, but these general categories are useful:
- 4 GB: Extremely limited for modern Windows gaming
- 8 GB: Usable for older games, esports titles, and lightweight games
- 16 GB: A practical target for many current games
- 32 GB: Useful for demanding games, heavy multitasking, content creation, or extensive modifications
Integrated graphics also reserve part of the system memory, leaving less RAM available to Windows and the game.
Close Memory-Heavy Applications
Open Task Manager and sort processes by Memory.
Close applications you recognise and do not need. Do not terminate unfamiliar Windows processes randomly.
Browsers, game launchers, communication apps, editing software, and background utilities can collectively use several gigabytes of RAM.
Keep the Windows Page File Enabled
Do not disable virtual memory to “free performance.” When physical RAM becomes full, the page file helps prevent applications from immediately failing.
Let Windows manage its size unless you have a specific technical reason to configure it manually.
An SSD makes paging less painful than an HDD, but it does not replace physical RAM.
Use Dual-Channel Memory When Supported
A single RAM module can limit memory bandwidth. Installing a matched second module may improve performance, particularly on systems using integrated graphics.
Compatibility matters. Check:
- RAM generation
- Module capacity
- Supported speed
- Available slots
- Laptop or motherboard limits
This is one of the few inexpensive hardware changes that can sometimes make a meaningful difference without replacing the GPU.
Can You Increase FPS Without a GPU Upgrade?
Yes, especially when poor settings, overheating, background activity, insufficient RAM, or slow storage are holding the system back.
The most effective ways to increase FPS without a GPU upgrade are:
- Lower resolution or render scale.
- Disable expensive graphics effects.
- Use FSR, XeSS, or another supported upscaler.
- Update graphics drivers.
- Enable dual-channel RAM.
- Prevent thermal throttling.
- Move the game to an SSD.
- Close background software.
- Set a stable FPS limit.
- Use game-specific configuration files carefully.
An SSD normally improves loading times and asset streaming more than raw average FPS. However, it can reduce pauses caused by slow asset loading in open-world games.
Add an internal link to SSD vs HDD for gaming for readers considering a storage upgrade.
Use a Sensible FPS Cap
An unstable 35–60 FPS range can feel rough because frame times constantly change.
Try capping the game at a value the PC can maintain:
- 30 FPS for demanding cinematic games
- 40 FPS for a smoother compromise
- 45 FPS when the system usually stays above it
- 60 FPS for esports and lighter titles
A stable cap can also reduce heat, fan noise, and sudden performance drops.
Use Dynamic Resolution
Dynamic resolution automatically lowers internal rendering resolution when the frame rate drops. It then raises the resolution when more performance becomes available.
Set a realistic target such as 30, 40, or 60 FPS. This is especially useful in games where some areas are much more demanding than others.
Best Tools and Software for Boosting FPS Safely
Most “one-click FPS booster” applications do little more than close programs, change Windows settings, and display aggressive marketing claims. Some may install unwanted software or make changes that are difficult to reverse.
Use trusted tools with a clear purpose.
Recommended Tools
NVIDIA App
Useful for:
- Official driver updates
- Per-game settings
- Performance monitoring
- Supported latency and graphics features
AMD Software: Adrenalin Edition
Useful for:
- Driver updates
- Per-game graphics profiles
- Performance metrics
- Radeon tuning
- Frame-rate controls
- Supported Radeon upscaling features
Intel Driver & Support Assistant
Useful for identifying supported Intel driver updates, particularly on PCs using Intel integrated graphics. Laptop users should also check whether their manufacturer recommends an OEM-specific driver.
MSI Afterburner and RivaTuner Statistics Server
MSI Afterburner is a widely used hardware-monitoring and GPU-tuning utility that can display performance data while you play.
It is useful for monitoring:
- FPS
- Frame times
- GPU usage
- CPU usage
- Temperatures
- Clock speeds
- Fan behaviour
Use it as a diagnostic tool before touching its overclocking or voltage controls. Download it only from MSI’s official website to avoid fake or modified installers.
Task Manager
Windows Task Manager is often all a beginner needs to identify unnecessary background programs, high memory usage, storage activity, and startup applications.

Advanced Low-End PC Gaming Optimisation
Once the basic changes are complete, advanced users can test the following methods.
Edit Game Configuration Files
Some games store additional settings in .ini, .cfg, or .xml files. These files may expose options that are unavailable in the normal settings menu.
Possible adjustments include:
- Lower shadow resolution
- Reduced grass density
- Shorter object-rendering distance
- Disabled post-processing
- Lower particle counts
- Reduced texture-streaming budgets
Back up the original file before editing it. Avoid downloading unknown “performance configs” because they may contain inappropriate commands, break updates, or violate competitive-game rules.
Disable High-Resolution Texture Packs
Some games install optional texture packs automatically. Removing them can lower VRAM use and free storage without affecting gameplay mechanics.
Test Older Rendering APIs
A game may support more than one graphics API, such as DirectX 11, DirectX 12, or Vulkan.
The newest option is not always fastest on old hardware. Test each supported mode in the same location and compare:
- Average FPS
- Stuttering
- Loading time
- Crashes
- Input responsiveness
DirectX 11 may run better on some older GPUs, while Vulkan or DirectX 12 may perform better in other games.
Avoid Unverified Registry Tweaks
Many gaming “optimisation” guides recommend copying registry commands without explaining what they change.
Avoid tweaks that promise to:
- Unlock hidden CPU power
- Double internet speed
- Add virtual VRAM
- Remove all input lag
- Increase FPS instantly
- Disable dozens of Windows services
A registry tweak cannot create processing power that the hardware does not have. Poorly chosen changes can cause instability, security problems, or broken Windows features.
Practical Before-and-After Optimisation Example
Suppose an entry-level laptop runs a multiplayer game at 22–32 FPS using these settings:
- 1920 × 1080 resolution
- Medium preset
- High shadows
- Ambient occlusion enabled
- 100% render scale
- Browser open in the background
- Balanced power mode
The player makes the following changes:
- Changes resolution to 1600 × 900
- Sets shadows to Low
- Disables ambient occlusion
- Reduces render scale to 85%
- Closes the browser
- Enables Best performance power mode
- Caps the game at 40 FPS
The result might be a much steadier experience near the chosen cap. The exact improvement will depend on the game, processor, graphics hardware, RAM configuration, temperatures, and driver.
The important lesson is not the example number. It is the method: reduce the largest workloads first, test in the same area, and prioritise stable frame times.
Common FPS Optimisation Mistakes
Avoid these mistakes when trying to improve gaming performance:
- Changing every setting at once
- Installing unknown FPS booster programs
- Setting Windows process priority to Real-time
- Disabling security software permanently
- Turning off the page file
- Downloading drivers from third-party websites
- Overclocking before checking temperatures
- Using an uncapped frame rate on an overheating laptop
- Assuming Low textures always improve FPS
- Confusing internet latency with rendering FPS
- Running multiple overlays and monitoring tools
- Expecting optimisation to overcome unsupported hardware
Also check the game’s minimum requirements. If the processor or GPU lacks a required feature, settings changes may not solve the problem.
Consider creating a guide to best lightweight games for low-end PCs for players whose current hardware cannot run newer releases reliably.
FAQS,
How can I increase FPS in games on a low-end PC quickly?
Lower the resolution, set shadows and reflections to Low, disable ambient occlusion, close background programs, enable Game Mode, and update the graphics driver. These changes usually provide the fastest improvement.
What is the best resolution for a low-end PC?
Start with 1600 × 900. Use 1280 × 720 when the game still struggles. Resolution scaling between 70% and 90% can offer a better balance when available.
Does adding RAM increase FPS?
It can, especially when the system has too little memory, uses integrated graphics, or runs single-channel RAM. Extra RAM usually improves stuttering and multitasking more than raw FPS.
Will an SSD increase gaming FPS?
An SSD normally improves loading times and asset streaming rather than average FPS. It can reduce storage-related pauses in games that frequently load large areas or textures.
Should I use Game Mode on a low-end PC?
Yes. Keep Game Mode enabled unless testing shows that a specific game performs worse with it. It is a safe and reversible setting.
Is 30 FPS good for gaming?
A stable 30 FPS is acceptable for slower single-player, simulation, and strategy games. Competitive shooters and racing games usually feel better at 60 FPS or higher.
Does lowering texture quality increase FPS?
Only in some situations. Texture quality matters most when the game exceeds available graphics memory. Shadows, reflections, volumetric effects, and resolution usually have a greater effect on GPU performance.
Can FPS booster software damage a PC?
Legitimate monitoring tools are generally safe when downloaded from official sources. Unknown booster programs may install unwanted software, disable important services, or make unstable system changes. Avoid programs promising unrealistic performance gains.
Does V-Sync reduce FPS?
V-Sync can limit FPS to the monitor’s refresh cycle and may increase input delay. However, it can also remove screen tearing. Test it both on and off, or use adaptive synchronisation when supported.
Why does my FPS drop after playing for several minutes?
The system may be overheating and reducing its clock speed. Monitor temperatures, clean vents, improve airflow, and test whether the FPS remains stable when the hardware stays cooler.
Conclusion
You do not need perfect graphics settings to enjoy a game. Smooth movement, stable frame times, and responsive controls matter more than high-resolution shadows or realistic reflections.
To increase FPS in games on a low-end PC, begin with resolution, render scale, shadows, volumetric effects, and background programs. Then update your drivers, select an appropriate Windows power mode, check temperatures, manage RAM usage, and cap the frame rate at a level the system can maintain.
Avoid random registry hacks and suspicious booster software. Reliable optimisation is a controlled process: change one setting, test it in the same scene, record the result, and keep only the adjustments that produce a real improvement.
Your PC may still have hardware limits, but proper configuration can often turn an unstable, frustrating game into a smoother and far more enjoyable experience.
