I'm using the "radeon" driver on Linux. If your code is expecting AMD cards, your hardware detection is not seeing it on my system.

Thanks for the report! Could you send me the output of "glxinfo"?

As this is an older AMD card, could you also test if the "fast animated textures" patch even does anything?

1. Set mipmap levels to 0
2. Check/compare FPS numbers with foamfix.cfg -> textures.fasterAnimation=2, and textures.fasterAnimation=0

glxinfo.txt

GLXInfo attached.
textures.FasterAnimation was 1 initially

There's not much difference.

Fixed in 0.10.0.
