GamerTuneGame on. Monitoring off.
Monitoring pauses entirely during fullscreen and borderless games, and benchmarks including 3DMark, Cinebench, and Geekbench. No polling or automatic settings changes interfere while you play or measure performance.

Know what changed, choose what matters, and keep your Windows gaming settings where you want them.
01 / Status
Catch changes before your next game.
Windows and driver updates can silently turn HDR off or reset your refresh rate. The Status dashboard detects settings drift and groups it by section, so you can see what changed without checking every Windows menu.

02 / Gaming
Fix drift once. Or keep it fixed.
Use Monitor to choose what GamerTune watches, Want to set your preference, and Auto-apply to keep that individual setting correct automatically. Auto-apply is opt-in and off by default. Prefer to decide each time? Review staged changes and fix drift in one click with Apply.

03 / General
Start with a preset. Stay in control.
Three presets give you a starting point across every tab. Every change is reversible and logged, so you can experiment and retrace your steps.
- Apply recommended The safe preset
- Apply extreme Every tweak
- Reset all to defaults Return to Windows defaults
04 / Display
Keep the display you paid for in tune.
Track HDR, refresh rate, resolution, and Dynamic Refresh Rate (DRR) per display. See when your configuration changes and restore your preferences, so a driver update does not leave you playing at the wrong refresh rate.

A closed loop
Detect → Decide → Apply & verify
- 01
Detect
Check for drift on a 30 s poll. Monitoring pauses during games and benchmarks.
- 02
Decide
You choose what to monitor and whether to enable auto-apply, setting by setting.
- 03
Apply & verify
Apply the change and read the value back. Before, target, and after values are logged.
Inspectable and reversible
Security.
Your trust matters.
GamerTune asks to change your Windows settings. You should be able to inspect how it works, understand the access it needs, and undo every change.
That is why the source, release checks, and change records are available for you to examine.
Inspect the sourceUser mode, not the kernel
GamerTune runs in user mode with no kernel drivers, hooks, or DPC callbacks. It does not install a component inside the Windows kernel to monitor your settings.
Windows asks before elevated changes
System-wide (HKLM) changes go through an elevated helper that shows a standard Windows User Account Control (UAC) prompt. Per-user changes are direct. You can see when a change requires administrator access.
Undo it. Check it yourself.
Every change is reversible and written to a change log with before, target, and after values, plus a copy-paste verify command. You can inspect what actually changed and verify it independently.
Release and project checks
Each release is scanned on VirusTotal, and the project runs OpenSSF Scorecard. These provide malware scan results and checks of project security practices for you to review.
Source you can inspect and rebuild
Open source under the MIT license, with reproducible, deterministic builds. You can inspect the code and reproduce a build to check that the download matches its source.
One network exception
The app makes no network calls except the GitHub Releases update check. Your settings monitoring stays on your PC.
Questions
FAQ
Honest answers about access, safety, performance, and updates.
Is GamerTune free?
Yes. GamerTune is free and open source under the MIT license, with no paid tier.
Does it change my settings without asking?
No. Changes are staged so you review them before clicking Apply. Per-setting auto-apply is opt-in, off by default.
Is it safe, and what access does it need?
GamerTune runs in user mode with no kernel hooks, drivers, or process spawning for reads. Writes to HKLM go through an elevated helper you approve with UAC. Every change is reversible and logged, every release is scanned on VirusTotal, tracked with an OpenSSF Scorecard, and built reproducibly.
Will it hurt my game performance?
No. Polling pauses during fullscreen and borderless games and during benchmarks. A check costs about 10 ms per tick, and while idle it uses about 23 MB of memory (RAM), a tiny amount, less than a single web browser tab.
Does it work on Windows 10?
No. GamerTune supports Windows 11 only for now.
How do updates work?
GamerTune checks GitHub Releases on startup and installs the latest build in one click.
How do I verify my download?
Each release links its VirusTotal scans, and builds are reproducible and deterministic so you can confirm what you run matches the source.
