Boost FPS on a Low-End PC: Steps That Make a Real Difference
On a low-end PC every frame counts, and most of the gain comes from two places: game settings and resolution, and the health of the PC itself, meaning memory and heat. Here are the steps in order of impact, plus what isn't worth your time.

In the game: the biggest difference
- 01
Use upscaling
AMD FSR works on most graphics cards, even integrated ones, and so does Intel XeSS. Pick “Quality” or “Balanced”: the game renders at a lower resolution and scales up, so FPS rises clearly with a small loss in sharpness.
- 02
Shadows and lighting first
Shadows, volumetric lighting, reflections and fog are among the heaviest settings. Lower or disable them before anything else.
- 03
Set an FPS cap
If your FPS swings between 40 and 70, a cap at 60 plays smoother than the jumpy numbers.
PC health: the difference everyone misses
- 04
Dual-channel memory
Two matching RAM sticks instead of one give a clear boost, especially with integrated graphics, which use the same RAM.
- 05
Heat and dust
An old, dusty PC or dried thermal paste throttles itself minutes into a game. Cleaning and fresh paste can bring back performance lost over time.
- 06
An SSD
Running games from an SSD instead of a hard drive greatly cuts stutter and load times.
- 07
Laptop on the charger
On battery, laptops lower performance to save power. Play plugged in.
Windows: small, useful steps
- 08
Close background apps
Browsers, sync and chat apps take from CPU and memory that are already limited.
Task Manager › Startup apps
- 09
Turn on Game Mode
It prioritises the game when other apps are running.
Settings › Gaming › Game Mode
- 10
Update the graphics driver
Even integrated graphics improve with recent drivers. Get it from the vendor's site.
What isn't worth your time
- Periodic “RAM cleaner” apps: Windows manages memory itself, and constant flushing can add stutter.
- Registry cleaners: no effect on speed.
- Huge virtual-memory settings: they don't make up for missing real RAM.
- “Mega FPS” packs from unknown sources: they can carry malware or break Windows.
When is an upgrade the answer?
With 8 GB of RAM or less, or a hard drive, a simple upgrade to 16 GB or an SSD is usually worth more than any tweak. If you're not sure where to start, a technician can check your PC and tell you exactly.
Questions gamers ask
No. Tweaking gets the best out of your PC and removes what holds it back, but it can't add power that isn't there. The real difference is usually settings, heat and memory.
