--- Comment #2 from Lauri Niskanen ape3000@gmail.com 2009-05-10 02:02:36 --- Regression testing didn't give any clear results. I marked 1.1.20 as good, 1.1.21 as bad and limited the search to dlls/wined3d. I got only bad results till there were only 8 patches left for testing. At that point the game looked just like 1.1.20. I marked it as a good one. The next one was also a "good" one. Then there was only two patches left. Then I got bad cases and the only patch left was '[8513f64a0117ee7a6a15cb174a3c0c76e2f2b071] wined3d: Emulate R16G16F and R32G32F if GL_ARB_texture_rg is not supported.'
1.1.20 isn't really the good one since it seems render PC3 as PC2. With 1.1.21 the bug appears on (real) PC3, but it works on PC2. 1.1.21 works just like 1.1.20, if you use PC2 so the problem is in the new PC3 rendering that didn't exists at all on the 1.1.20.
The patch was made by Stefan Dösinger stefan@codeweavers.com, so he might know something about this problem. I added him to this bug.
