- How to improve FPS on a low-end gaming PC: updates, settings, upscaling and cleaning in a sensible order, plus a tracking example and when to upgrade.
The quickest gains on a low-end gaming PC come from game settings and resolution, not from system “boosters”. Lower demanding options, enable upscaling if available, update the graphics driver, close background apps and confirm the game runs on the right graphics chip. Cleaning dust and fixing thermal throttling can help too. This guide from the Editorial team, based on published specifications, manufacturer documentation and general knowledge, walks through the steps in a sensible order, shows what can go wrong and tells you when to stop and consider hardware.
Before you start
You need a way to see frame rate. Many games include a built-in counter, and Windows includes a performance widget in the Xbox Game Bar. You also need to know your hardware: open Task Manager, check the Performance tab for processor, memory and graphics card, and note your resolution.
Pick one repeatable scene in your game, such as a particular area or a replay, and note the frame rate there. Without a baseline you cannot tell whether a change helped or whether the scene simply varied.
Set aside an hour and avoid changing several things at once. Write each change in a notebook or text file so you can undo it if the game gets worse. Make sure you can sign in to Windows as an administrator, because driver installs need those rights, and keep a note of your current driver version in case you need to return to it.
Step-by-step: from easiest to most involved
- Record your baseline. Write down average frame rate and the worst dips in your test scene.
- Update the graphics driver. Download it from the graphics vendor, not a third-party site. Restart afterward.
- Check the game uses the right graphics chip. On systems with both integrated and dedicated graphics, open Windows graphics settings and assign the game to the high-performance option.
- Set a high-performance power mode. On laptops, plug in the charger. On desktops, check the Windows power plan.
- Close background programs. Browsers, launchers, overlays and cloud sync tools compete for memory and processor time.
- Lower the resolution or enable upscaling. DLSS, FSR and XeSS render at a lower resolution and reconstruct the image; availability depends on the game and hardware.
- Trim demanding settings. See the table below.
- Cap the frame rate. A steady cap near what your PC can sustain usually feels smoother than swinging between highs and lows.
- Install games on an SSD. It will not raise frame rate directly but can reduce loading stutter.
Which settings usually cost the most
Impact varies by game, so use this as a starting guide and confirm in your own test scene.
| Setting | Typical frame rate cost | Visual cost when lowered |
|---|---|---|
| Resolution or render scale | Large | Softer image |
| Shadows | Large | Small to moderate |
| Volumetric fog and lighting | Large | Small to moderate |
| Anti-aliasing | Moderate | More jagged edges |
| Textures | Small, unless video memory is exceeded | Blurrier surfaces |
| View distance | Moderate | Pop-in |
Textures are the exception: if your graphics card has limited video memory, a lower texture level can remove stutter dramatically even though it barely affects average frame rate.
Check temperatures and airflow
A hot system slows itself down to protect parts, a behavior called thermal throttling. If frame rate starts well and drops after ten minutes, heat is a prime suspect. Use a monitoring tool to watch processor and graphics temperatures during play, and compare them with the limits in the manufacturer documentation.
Power off and unplug the PC, then clear dust from intake filters, heat sinks and fans with compressed air while holding the fans still. Good cable routing also helps airflow; our guide on how to cable manage a gaming PC covers the basics. Never open a laptop or power supply unless you are comfortable doing so.
If temperatures look normal but performance still dips, check the power settings of the laptop or desktop. Some portable systems run slower on battery or in a quiet profile, and a few desktop boards have power-saving modes that limit boost speeds. Review the manufacturer documentation for the exact option names on your model.
Reduce background load while recording
If you record gameplay, the recorder competes with the game for resources. On a weak system, choose a lightweight tool and lower the capture resolution or frame rate. Our overview of game recording software for low-end PC builds compares options at a general level.
Windows and memory checks
A few system-level settings are worth checking once. Turn on Game Mode in Windows settings, which reduces some background activity while a game is running. Open the Startup tab in Task Manager and disable programs you do not need at login; fewer startup items mean more free memory when you launch a game.
Memory configuration matters on low-end systems. Two matched modules run in dual-channel mode, which commonly gives better performance than a single module of the same total size, especially on systems that use integrated graphics. Check the motherboard manual for which slots to use. Also keep at least 10 to 15 percent of your system drive free, since a nearly full drive can cause slow loading and sluggish updates.
If your PC has only integrated graphics, expectations need adjusting. These chips share system memory and have limited power, so lower resolutions, reduced render scale and older or lighter titles are the realistic route. Faster memory in dual-channel often helps such systems more than any other single tweak.
What can go wrong
- Driver problems: a new driver occasionally causes crashes. Keep the previous installer so you can roll back.
- “Optimizer” tools: registry cleaners and booster apps promise a lot and often change little, and some cause problems. Skip them.
- Overclocking: raises heat and instability; avoid it on weak coolers or unnamed power supplies.
- Disabled services: turning off Windows components can break updates or security.
- Static and force: when cleaning inside, ground yourself and never pull on cables.
Worked example: tracking changes
The figures below are invented for illustration. Assume a game averages 38 fps at 1080p on high settings. After updating the driver and closing background apps, you record 41. Setting shadows to medium and turning off volumetric fog brings it to 52. Enabling an upscaler on its quality mode reaches 61. A table like this shows which step earned its place and which you can undo. Keep a simple note for each change.
Safety notes for cleaning and changes
Before opening a desktop, shut it down, switch off the power supply and unplug the cord, then press the power button once to discharge residual power. Touch bare metal on the case to ground yourself. Do not use a vacuum cleaner directly on components, because it can generate static, and avoid spraying liquids near circuit boards. If you are unsure about any step, a local repair shop can do it quickly.
When to stop and consider hardware
Stop tweaking when settings are already low and the game still falls short. Open Task Manager during play: if memory is nearly full, a matched memory pair may help; if the graphics card sits at full load, it is the limit; if one processor core is maxed out, the processor is the limit. Always confirm that your power supply and motherboard support the part before buying.

Frequently asked questions
What is the fastest way to get more FPS on a weak PC?
Lower the resolution or turn on an upscaling option such as DLSS, FSR or XeSS if your game and graphics card support it, then reduce demanding settings like shadows, volumetric effects and anti-aliasing. These changes usually shift frame rate more than driver tweaks or system cleanup. Make one change at a time so you can see which one helps.
Does closing background programs really help?
It can, especially on systems with 8GB of memory or a modest processor. Browsers with many tabs, launchers, overlays and sync tools all use memory and CPU time. Close what you do not need before launching a game, and check Task Manager for anything using a surprising share of resources. The gain varies, so treat it as one step among several.
Will adding more RAM improve FPS?
Only if memory is the bottleneck. If your PC has 8GB and constantly uses nearly all of it, moving to 16GB in a matched pair can reduce stutter and improve minimum frame rates. If you already have enough memory, extra capacity will do little. Check memory use in Task Manager during play before buying.
Is it safe to overclock a low-end gaming PC?
It carries risk and is not recommended as a first step. Overclocking increases heat and power draw, and weak coolers or budget power supplies may not cope. Start with settings, drivers and cleaning. If you do experiment later, follow manufacturer guidance, change values in small steps and monitor temperatures closely.
When is it time to upgrade hardware instead of tweaking?
When settings are already at the lowest practical level and the game still runs below your target, hardware is the limit. Check which component is maxed out during play: graphics card, processor or memory. Then upgrade the one that is holding the system back, after confirming that your power supply and motherboard support it.
