Hi! I have been enjoying Minetest immensely these last few days but it is simply unplayable on my PC because it is unable to maintain a stable framerate, be it 30 or 60 fps. Sometimes when viewing giant block structures or sometimes at random times the FPS drops to 24 or less and I tried to lower the rendering distance (I think it’s called differently) but although it does improve, it shouldn’t be fixed if my PC is 100% capable of running it well, and in fact on Windows it runs beautifully.
Specs: RTX 3060, Ryzen 5 5600X, 16GB DDR4, SSD.
I thought it was a problem with my distro (Garuda Linux) so I installed another one (KDE Neon) and it’s exactly the same, I also switched from X11 to Wayland and it’s still the same, I honestly don’t know why this happens but it’s not hardware deficiency, also I tried the git version (via AUR), flaptak and snap, the problem persists,
In Windows it works perfectly without any problem, it runs great and with everything set to maximum but in Linux it is simply unplayable.
I would like to add something important, and it is that in Linux none of the compilations uses the GPU to the maximum, according to nvtop it is being used but in very little measure, and it seems that the CPU does everything.
I set the options because I had issues with screen tearing when moving around windows. It’s a very old setup, though.
ForceCompositionPipelineandTripleBufferpevents screen tearing on my machine when moving windows aroundAllowIndirectGLXProtocolis just a performance option. Indirect GLX protocol is slower.Full options for the driver are available here: http://http.download.nvidia.com/XFree86/Linux-x86_64/535.113.01/README/xconfigoptions.html
Edit Here’s an exhaustive article on the DRM. It basically manages what and when applications can have access to the GPU instead of the applications “fighting” over it.
