--- Comment #23 from Simone Scanzoni nonno.cicala@tiscali.it --- Mesa 9.2-devel (git-4deefd9) showed the problem here with TF2, I don't have CSS. Added patches: r600g: emit a ps partial flush after CP DMA r600g: enable CP DMA on r6xx (v3) and the problem persisted. Then reverting commit 1eedebc65b02130ef7a27062a1ed67972a317a08 fixed the issue. Mesa 9.0.3 works. HD3850 (RV670) AGP, kernel 3.8.0
First comment so I want to thank the devs for their work. :)
