FPS Booster for Windows – Free Game Performance Tool

Built different

Why Game FPS Booster works better than alternatives.

Most boosters are bloated or unsafe; this one is tiny, transparent, and uses only standard Windows APIs.

Lightweight and portable

At 76 KB, Game FPS Booster runs instantly without installation or .NET dependencies on Windows 10 and 11. Just download and click. No clutter, no background services stealing your RAM.

Completely reversible

Every operation is undone when you close the app or disable the watcher. Your system returns to normal settings automatically. No registry tweaks, no permanent changes.

Zero telemetry

Game FPS Booster never phones home, never tracks you, and never bundles extra software. It's open-source and auditable.

Safe for competitive play

Anti-cheat systems like EasyAntiCheat, BattlEye, and Vanguard are protected from priority throttling. Your game stays fair and unflagged.

Real results

See the difference in your frame rate.

Watch freed memory and quieted processes update in real time as Game FPS Booster reclaims system resources. The circular gauge shows exactly how much RAM load drops after each boost pass.

Working-set trimmingUnused memory pages from background processes are returned to the system so your game gets more breathing room.

Priority throttlingNoisy background tasks are dropped to lower priority, leaving CPU cycles free for your game.

Power-plan activationHigh Performance mode stops the CPU from downclocking between frames, eliminating frame dips caused by power saving.

Common questions about Game FPS Booster

Will this void my game warranty or get me banned?

No. Game FPS Booster uses only public Windows APIs—the same ones Windows itself exposes. Anti-cheat systems are explicitly skipped, so competitive games remain protected.

Do I need administrator rights?

No. All three core operations work through standard user-level Windows APIs. You may need admin rights only to change the power plan, depending on your PC's group policy settings.

What happens if I close the app?

All changes are reversed. Memory trimming is temporary, background priorities reset to normal, and you can manually reactivate your previous power plan. Nothing is permanent.

Can I run the watcher in the background?

Yes. Enable the optional background watcher to automatically boost when RAM usage crosses your threshold (default 80%). A system-tray icon shows real-time memory load.

Will it work on my old laptop?

Yes, if it runs Windows 8.1, 10, or 11 and has .NET Framework 4.8 installed. Windows 10 and 11 come with it; Windows 8.1 users can install it free from Microsoft.

Does it conflict with other gaming software?

No known conflicts. Game FPS Booster is minimal and non-invasive. If you run multiple boosters, disable the watcher in each to avoid competing boosts.

How much FPS will I gain?

Gains depend on your system load and specs. On low-end PCs with many background tasks, frame rate smoothing is often noticeable. On high-end systems, gains are subtle.
