FPS tanks when using shaders on mesa 20.1.3-1 #4427

Open ErikReider opened 4 years ago

The performance tanks down to around 20 fps on my paper server (not on this PC). I've got a Radeon 5700XT, Ryzen 7 1700 3.9Ghz overclock, 3000mhz 16 of ram, Manjaro with kernel 5.7.9-1-MANJARO running on X11. I've got the same issue in Windows too. The GPU usage is around 90% while the CPU is at 10% (one core pegged at 80-90%, only without shaders). With Shaders, the CPU usage is around 30% which could indicate a CPU bottleneck. Never really had this issue be this extreme on the 1.15 release but it was still there. I usually get 25fps when running with 12 chunks and 60 when at 8 chunks.

I've tried the latest BSL shaders, Sildurs enhanced default (lowest settings), SEUS Renewed (which doesn't work but that's a different issue...), Sildurs Vibrant Shaders Extreme VL. All of them experience performance issues.

I'm running at 12 chunks and sometimes 8 chunks (this could be the reason but idk. the difference between these is 84585600 blocks which is insane). My Optifine version is "OptiFine 1.16.1 HD U G2 pre9", installed through the jar file directly as a new profile (no forge, no mods).

Is this still an issue on the full release of optifine 1.16.1?

ErikReider commented 4 years ago

@unicornbloods Yeah but only in Linux though. Render regions doesn't work with the MESA drivers. With it enabled, the FPS tanks while in Windows it works as expected

I am having the same issue on a Ryzen 3 3200G + RX 550, Ubuntu 20.10.

I fixed the issue a few months ago by running a script that enables some Mesa variables. I've posted the script here
