/ What it does

Built for people
who actually care.

01
Game Profiles

One-click presets for Fortnite, Valorant, CS2, Apex, Warzone, and Max Performance. Registry and service configs tailored per engine.

02
Network Tweaks

Nagle's algorithm off. TCP buffer tuning. DNS flush. Throttling index adjusted. Built to cut in-game ping variance and jitter.

03
Deep Debloat

24 Windows bloat targets removed — Cortana, Xbox Game Bar, OneDrive telemetry and more. Clean, stable, and nothing broken.

04
Latency Tester

Built-in benchmark. Test before and after. See your actual improvement in milliseconds, not just feel it.

05
Registry Backup

Auto-backup before every change. Fully revertible from within the app. Nothing is permanent unless you want it to be.

06
Custom Profiles

Build your own tweak stack. Save as JSON. Share with friends or import community configs. No limits on what you can build.

/ Game presets

Pick your game.
We handle the rest.

Each preset is tuned for that game's specific engine, anti-cheat, and input model — not just copy-pasted registry keys.

Fortnite
Zero Build + BR · Creator's pick

Input lag reduction, render thread priority, network buffer tweaks for EGL + Epic overlay. Jayden's personal config.

Valorant
Precision · Anti-cheat safe

Vanguard-friendly OS tweaks. CPU scheduling and DPC latency reduction for Riot's engine without touching game files.

CS2
Source 2 · Frame pacing

GPU scheduling, timer resolution, and frame time consistency for high-refresh-rate play on Source 2.

Apex Legends
High Hz · Memory tuned

Respawn engine profile. Memory priority, streaming tuning, crash prevention for consistent sessions at high frames.

Warzone
VRAM focused · IW8 engine

Texture streaming, shader cache, and network tweaks for large lobby stability on COD's engine.

Max Performance
Nuclear · All tweaks on

Every performance switch flipped. Best for dedicated rigs. Visual effects off, telemetry dead, background services culled.

"Most people tweak their settings.
I tweaked the OS itself
because the game starts before
you even hit launch."

★★★★★

"I went from stuttering in every POI to a solid 240 fps on my 3060. The Fortnite preset alone is worth it. Never alt-tabbing again."

"Was skeptical at first. Ran the benchmark, saw my DPC drop from 580µs to 110µs. My Valorant feels buttery smooth now. Huge W."

"Cleanest optimizer I've used. No bloatware, no fake promises, just real tweaks. The registry backup saved me when I messed with things I shouldn't have. 10/10."

/ Common questions

FAQ.

Yes. Jafoo Tweaks is fully open source — read every line on GitHub before running. It auto-backs up your registry before any change, and everything is revertible from inside the app.
No. Jafoo Tweaks only touches Windows OS-level settings — power plans, registry keys, background services. It never modifies game files or injects into processes. EAC and Vanguard have no reason to flag it.
Yes, fully. Jafoo Tweaks runs on both Windows 10 and Windows 11 with no changes needed.
Accessibility. No messing with PowerShell execution policies. No copy-pasting commands. Just download, run as admin, and go. Source is still public on GitHub for anyone who wants to verify it first.
Yes. Every tweak can be reverted from the Revert tab. A registry backup is also saved to %AppData%\JafooTweaks\ before anything is applied.
