Good morning, I have a Q6600 with an AMD Radeon R9 280X and Batocera 34.
All emulators go very well, including Sega Model 2 and PSX. I´m having problems with some steam games that should work ok like CUPHEAD, it has very low FPS in the title (frame by frame in the menu also).
On the other hand Street of rage 4 runs perfectly as other games too. In Windows cuphead runs ok, so I guess is a drivers problem.
The drivers are detected as
GRAPHICS API - OPENGL 2.0
VENDOR - AMD
RENDER - AMD TAHITI (LLVM 13.0.0, DRM 2.50, 6,17,5)
VERSION - OpenGL ES 3.2 MESA 22.03
Shaders - OpenGL ES GLSL ES 3.20
I tried with different proton versions but the result is the same.
Thanks in advance!
