Real game optimizations.
No placebo switches.
FrameTweaks is a lightweight desktop app that performs genuine system actions — every toggle does something measurable. It detects your OS and only shows the tweaks that actually work on your machine.
Licence key required. Windows 10/11, modern Linux, and beta support for macOS 15+.
What it actually does
🚀 High process priority
Point at your game and raise its scheduling priority (High on Windows, lower nice on Linux) so it gets the CPU first.
⚡ Performance power mode
Switches the active Windows power plan to High Performance, or the
Linux CPU governor to performance — when your hardware
supports it.
🧹 Clear cached memory
Purges the Windows standby list or drops the Linux page cache to free memory the OS was holding back.
🎮 Per-game profiles
Save the toggles and target process for each game. Profiles are encrypted on disk with a password-derived key (PBKDF2 + Fernet).
🔐 Honest about privileges
Detects admin/root at startup and prompts cleanly (UAC on Windows, pkexec on Linux) only when an action truly needs it.
How it works
- Detects your OS & hardware. Unsupported tweaks are greyed out with a tooltip explaining why — never faked.
- Runs unprivileged. It asks for elevation only for the specific action that needs it.
- Encrypts your profiles. Your password never leaves your machine and is never stored.
