radeonsi: Hyperdimension Neptunia Re;Birth1, very slow
I have confirmed with an ADM RX 6600 it is using the radeonsi driver, so it's an OpenGL game.
Other information:
- Oddly the CPU and GPU are practically doing nothing.
- If I enable
LIBGL_ALWAYS_SOFTWARE
performance goes up to 20fps. - I'm using Arch Linux with MESA 22.3.3-3.
- Before MESA 22.3.3 the game would show a black screen, and only
MESA_EXTENSION_MAX_YEAR=2005
would fix it. - I finished this game in the past with an AMD R9 380 running at 60fps the entire time.
If necessary I can give logs or try it out with the R9 380, since I still have it.
Solution
Thanks to the participants.
The only solution we found:
- Disable REBAR/SAM with
radeonsi_disable_sam=true
or in UEFI. - Run with
AMDGPU_DEBUG=nowc
.
This seems to affect AMD Ryzen 5000 series only.
