on bug 93292
from Jan-Marek Glogowski
working command line with patch to get the shader log: R600_SB_DSKIP_START=94 R600_SB_DSKIP_END=94 R600_SB_DSKIP_MODE=63 glretrace thea.trace working command line without the patch to verify shader bug: R600_SB_DSKIP_START=94 R600_SB_DSKIP_END=94 R600_SB_DSKIP_MODE=1 glretrace thea.trace In the end I'm just using the llvm backend (R600_DEBUG=llvm). I just see a minimal difference on this HW in game of ~0.5 frames (slower LLVM). Actually I had other small rendering glitches with the SB shader backend, which I didn't track down.

The original (large) apitrace had ambient occlusion (AO) activated AFAIK, but I deleted it, so I don't know. AO was fixed for me with a patch in the last week. As my hardware is already slow (just 15fps in the game), enabling this renders the game unplayable, but now I get soft shadows at the price of ~50% frame drop.
