CorePin vs Feral GameMode

CorePin is a per-game CPU optimization utility for Windows 10 and 11. It lets you configure core placement, scheduling, process priority, power behavior, and background workloads, then apply those settings automatically when a configured game starts and restore temporary changes after it exits. The utility detects processor topology and offers V-Cache, frequency, hybrid-core, cache-group, no-SMT, and manual profiles. Its library can discover games from Steam, Xbox app/Microsoft Store, Epic Games Store, GOG Galaxy, EA app, Ubisoft Connect, Battle.net, Amazon Games App, and Meta PC VR. CorePin also supports supported VR companion placement and OpenXR launch behavior. Gameplay profiling reports FPS, frame-time, CPU/GPU behavior, memory, storage, and available hardware telemetry; System Benchmark offers Quick, Full, and Demo modes using repeatable CPU and DirectX workloads. CorePin is free: free. It operates locally, though its interface may make outbound HTTPS requests for release checks, artwork, and provider metadata. Performance results vary with the game and system, and improvements are not guaranteed.

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.
