This repository is a comprehensive, community-driven guide for optimizing gaming performance on Linux. It covers a wide range of topics from basic setup (distribution choice, GPU drivers) to advanced tweaks (kernel parameters, CPU cache topology, custom Wine/DXVK compilation, input lag benchmarking). The only executable code consists of two shell scripts that implement CPU core pinning using cpusets, which can be reused to isolate game processes to specific CPU cores for reduced cache contention. The guide is well-structured, frequently updated, and serves as a valuable reference for Linux gamers seeking performance improvements. It is not a software application but a documentation resource with minimal code.
The LLM identified 2 files worth highlighting for reuse:
A shell script that automatically detects AMD Ryzen CPU cache topology (CCX/CCD) using lstopo, creates two cpusets ('theGood' and 'theUgly'), redirects all processes to one cpuset, and optionally moves a game launcher (e.g., Lutris) to the other cpuset. This isolates the game to a dedicated L3 cache domain, reducing cache misses. The script is self-contained, parameterized, and demonstrates non-obvious system administration skill. It can be extracted and reused for any CPU-pinning scenario on Linux.
A companion script that reverses the cpuset splitting performed by tasks_redirect_generic.sh. It moves all processes back to the root cpuset and removes the custom cpuset directories. This is a simple but essential cleanup routine, demonstrating idempotent resource management. It can be reused as a teardown pattern for any cpuset-based isolation workflow.
