More FPS. Less stutter.
One click.
Fusion Optimizer applies 65+ reversible Windows tweaks, boosts your games while they run and shows you before/after in a built-in benchmark. Every change is backed up and undone with one click.
What it does
Not a "turbo button" – the optimizer removes what Windows takes away in the background. On average PCs and laptops the difference is big, on high-end rigs you get smoother frametimes and lower input lag.
System tweaks
Game DVR, scheduler priorities, power plan, VBS/core isolation, NVIDIA full clocks, MSI mode, timer resolution, Nagle, telemetry – with impact rating and risk label.
Game Boost
Detects FiveM, GTA V, Fortnite, Retrac and Siege. Sets process priority, switches the power plan, holds a 0.5 ms timer and throttles Discord & browsers – all automatic, all reverted afterwards.
Benchmark
Measures timer accuracy, scheduler jitter and CPU throughput in 10 seconds. Run it before and after – the dashboard shows the difference in percent.
Health check
Shows what holds your PC back right now: VBS active, wrong power plan, old GPU driver, pending reboot, full disk, too many startup apps – each with a fix button.
Cleaner & startup
Temp files, shader caches, FiveM/Fortnite/Siege caches, update leftovers. Disable startup programs like in Task Manager – nothing gets deleted.
Everything reversible
Every tweak saves the original value before changing it. "Reset all" restores exactly what was there. Plus optional Windows restore point.
Game profiles
Each game gets its own page: process tweaks, cache cleaning, fullscreen-optimization flags and one-click graphics profiles written straight into the game's config.

FortniteGameUserSettings.ini profiles, shader cache, launcher priority

Download, run as administrator, follow the setup wizard: benchmark → restore point → recommended profile → your game. Restart Windows once. Done.

FAQ
Windows SmartScreen says "unknown publisher"
The EXE isn't code-signed (that costs a few hundred euros a year). Click "More info" → "Run anyway". The source of the tweaks is documented in the app and everything is reversible.
Why does it need administrator rights?
Tweaks change HKLM registry keys, services, the power plan and boot settings. That's impossible without admin rights – the app refuses to start without them.
Does it make my hardware faster?
No. It stops Windows from holding your hardware back. On a high-end PC you'll see little FPS gain but more stable frametimes and less input lag; on average PCs and laptops the difference is 5–15 %.
How do updates work?
Automatically. The app checks on start and every 6 hours, downloads the new version in the background and installs it when you're not in a game.
Can I undo everything?
Yes. Backup & Log → "Reset all" restores every original value. If you created a restore point, Windows can roll back too.
