Yesterday's performance bot results, http://kegel.com/wine/yagmarkdata/E8400-GT_220-Ubuntu_10.04_LTS-e8400-wine-1... show that the Heaven 2 d3d9 benchmark had a couple 10% improvements in the past week (up from 10 to 11 and then 12 fps). If we're going to see improvements in a benchmark, that's the best one, since it probably matches modern games more closely than the others.
3dmark2001 had a very good day (http://kegel.com/wine/yagmarkdata/wine-1.1.44-19-vs-wine-1.1.44-72.txt) but returned to its poor scores thereafter. No idea why the one-day blip. (There was also an upward blip in heaven2_gl that day, but it was quite small.)
