Feral GameMode vs GameGain

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.

GameGain is Windows software intended to tune PC game performance, frames per second, and smoothness. It changes Windows registry and system settings affecting memory use, CPU prioritization, drive access, and graphics display speed. Full-screen applications receive priority for CPU power and access to more CPU cores. PGWARE says these adjustments can increase displayed frames per second and reduce lag and screen pop-in while large map files load. GameGain changes Windows directly rather than patching or modifying game files. Listed systems include Windows 10, 8, 7, Vista, XP, and Windows Server 2012, 2008, and 2003, with 32-bit and 64-bit support. The listed update is version 4.10.21.2024, recompiled with Delphi 2023 to fix small bugs and improve Windows 11 compatibility. Downloadable trials last 30 days. Listed plans are GameGain 4 at $4.99, paid once and a GameGain 4 license at $4.99 a month. The application can install updates internally.
