Linux Gaming
Gaming on Linux, without giving up your library
Linux is a fully usable gaming platform, but the details decide everything: which compatibility layer a game needs, which launch options it expects, and what to change when a frame rate or a graphics feature goes missing. NAnnersTech collects that knowledge here, one tested guide at a time.
Topics
What this section covers
Four categories, each built from guides that have been checked on real hardware before they are published.
Proton
Proton is how most Windows games reach Linux: the compatibility layer Steam uses to run them. This category covers choosing a Proton version, switching between official and community builds, and setting a build per game.
Game compatibility
What runs, what needs a tweak and what refuses to start. Compatibility notes here go beyond a simple works-or-not label, and explain the reason where one is known.
Performance tweaks
Getting a game to a playable frame rate on the hardware you have: upscaling and frame-generation tools, sensible in-game settings, and the trade-offs each one makes.
Troubleshooting
Launch failures, missing features after an update, graphics options that disappear, drivers and runtimes that disagree. Practical fixes, written in the order you should try them.
The Witcher 3 “DLSS Not Supported” Fix on Linux — DLSS Neural Rendering (2026)
The Witcher 3 reported “DLSS is not supported” on Linux after an update. This guide follows the fix from start to finish: choosing the Proton build that brings DLSS back, confirming it works, verifying DLSS Neural Rendering, setting up OptiScaler on Linux and applying the Steam launch options.
