There are hundreds of "Windows gaming tweak" videos on YouTube, and most of them are placebo. We benchmarked 30+ of the most popular tweaks and found 15 that actually deliver measurable improvements.
Tweaks That Actually Work
Each tweak below was tested on Windows 11 22H2 with an RTX 4070 + Ryzen 7 7700X. Results are average of 5 runs.
- ›1. Ultimate Performance Power Plan: +6 FPS in CS2
- ›2. Disable Visual Effects: +3 FPS, lower input latency
- ›3. Disable Cortana service: +2 FPS, fewer disk reads
- ›4. Disable SysMain (Superfetch): +4 FPS, especially during loading screens
- ›5. Enable Game Mode: +5 FPS in CPU-bound games
- ›6. Disable Notifications & Action Center: +1 FPS, no random stutters
- ›7. MSI Mode for GPU/NIC: -3ms latency, smoother frame pacing
- ›8. High-Resolution Timer (0.5ms): +4 FPS, much better 1% lows
- ›9. GPU Hardware Scheduling: +8 FPS in DX12 games
- ›10. CPU Process Priority Tweaks: +3 FPS in CPU-bound scenarios
- ›11. Disable Memory Compression: +2 FPS, less CPU stutter
- ›12. Disable Prefetch on SSD: +1 FPS, lower disk activity
- ›13. Enable Large Pages: +5 FPS in memory-heavy games
- ›14. Disable Background Apps: +4 FPS, fewer interruptions
- ›15. Reduce Startup Delay: -2s game launch time
Tweaks That Don't Work (Despite YouTube Saying So)
- ›"Disable Windows Defender" - measurable security risk, no FPS gain
- ›"Set GPU to dedicated mode" - already on by default
- ›"Disable services list" - most are needed, breaks Windows
- ›"Registry timer 0.0001ms" - Windows ignores values below 0.5ms
All 15 working tweaks are bundled in Latency Killer. Apply them all in one click - no manual registry editing required.
