Feral GameMode vs PotatoBoost

Feral GameMode is a free Linux daemon and library that lets games request temporary optimisations to the host operating system or game process. It can adjust the CPU governor, I/O priority, process niceness and scheduler policy, inhibit the screensaver, change GPU performance mode, pin or park CPU cores, and run custom scripts. Games and launchers with built-in support can activate GameMode automatically; other games can be launched with the gamemoderun command or a Steam launch option. GPU performance mode is supported for NVIDIA and AMD, while GPU overclocking is listed for NVIDIA. The project lists packages for Ubuntu, Debian, Solus, Arch, Gentoo, Fedora, OpenSUSE and Mageia, with possible availability elsewhere. Configuration uses a gamemode.ini file with options for GPU and CPU settings, filters, supervisor access and scripts. GameMode is maintained by Feral Interactive and is available under the BSD 3-Clause License (Revised). Its build depends on Meson, internal communication uses systemd, and development requires a C environment. For hybrid GPU commands such as optirun, automatic integration after game startup is unavailable; a wrapper with gamemoderun is described instead.

PotatoBoost is a Windows performance suite for tuning, cleanup, game settings, and backups. It detects PC hardware, recommends a matching plan, and lets users preview supported changes before applying a profile. Live Boost holds supported performance settings during a session and restores the saved state afterward. Maintenance tools cover memory use, startup entries, cleanup targets, Windows privacy checks, and game configuration. Supported setting changes are saved before they are applied, and Restore is available on the free plan. The maker gives no fixed FPS increase because results depend on the hardware, game, and current settings. PotatoBoost supports Windows 10 and 11 on x64 PCs, not ARM64, macOS, or Linux. It is free to use with the Free Forever plan; Premium Flexible costs C$6.99 a month after a 7-day free period, or Premium costs C$40 a year after a 7-day free period. The current installer is unsigned, and administrator approval is needed for protected Windows changes.
