Feral GameMode vs FrameCoach

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.

FrameCoach is a free game-graphics optimizer available on the web and Windows. It recommends settings from a user’s GPU, CPU, game, and target frame rate, then estimates how each setting may affect FPS. Users can edit the recommendations and watch the estimate change live. The web optimizer covers more than 160 GPUs, 250 CPUs, and 180 games, including Steam Deck, and supports NVIDIA, AMD, Intel, and handheld hardware. Its FPS figures come from a generalized model rather than live benchmarks, so scenes, drivers, and game versions can change the result. The free Windows app scans hardware, works offline, and offers recommendations for more than 180 games. Its beta can apply settings to supported Unreal Engine games while closed, backing up configuration and offering one-click undo. Windows 10/11, 64-bit, and no account are required. The maker says desktop hardware stays on the PC and nothing is uploaded.
