--- Comment #68 from Stefan Dösinger stefan@codeweavers.com --- Prior to version 1.3.20 we misinterpreted the polygon offset and that caused problems in games like Mass Effect 2 (flickering decals). FEAR sets an insanely large polygon offset (Half the Z buffer range), and the offset pulls the geometry in front of the camera. That's not supposed to matter because polygon offset is applied after Z clipping. On Nvidia that's not the case, so the geometry gets clipped away. The difference is demonstrated by attachment 37930.
It's interesting but not totally surprising that Nouveau is affected as well. I guess the polygon offset vs Z clipping behavior is due to the hardware design and not a simple driver bug.
