What is dmemcg-booster and how do I use it?

It's a systemd service for GPU memory cgroups; enable it pre-game launch on CachyOS or compile for your distro—prioritizes fullscreen apps instantly.

Does this work on NVIDIA GPUs too?

Patches target DRM/TTM, so AMD primary, but Intel iGPUs yes; NVIDIA's proprietary stack needs driver tweaks—watch for upstream.

Will Valve's patches make Linux gaming equal to Windows?

Closes vRAM gaps hugely for low-end hardware; pair with Proton Experimental, and 8GB rigs handle modern titles better than ever.

Is CachyOS safe for daily driving?

Gamer-optimized Arch spin—stable for Steam, but pacman updates demand care; test your workflow first.
