0003848: [Linux/SDL] OpenGL Stuttering (with fix)
Massive stuttering issues in OpenGL in Zandronum on Linux, practically unplayable, see here:https://www.youtube.com/watch?v=IGhT4Pp1YW0 [^]

Applying this fixhttps://pastebin.com/sm8H6vRk [^] fromhttps://forum.zdoom.org/viewtopic.php?f=2&t=46685 [^] fixes this entirely. I tried it by compiling the source with the changes by myself. The game is silky smooth afterwards.
No tags attached.

I compiled Zandronum 3.1 alpha 5bb6162acea1 with this patch and I still have movement that has a slight stutter. It's not possible to play competitively like this. Mouselook is otherwise smooth like the video. Run out of options here to get Zandronum perfectly smooth in Linux. I'm on Mint 20.2.

Running the Windows variant (3.0) in Wine actually works smoothly compared to the native linux builds.
