Tried with Ubuntu 9.04 x64 Tomb raider III - major slowdowns and breaks Crayon physics - no Breaks but very slow Counter strike 1.6 lower framerates (not much 3-5 fps of diference) Age of empires II a little slower, can't say if it is a wine regression or x64 fault haven't tried wine 1.20 on x86 yet. Flash 8 - Normal speed? can't tell if it's faster or slower it runs at normal speed anyway ubuntu 9.04 x86 Tomb raider III - runs perfecly smooth Crayon physics- smooth aswell Counter strike runs faster, hard to tell the diference only saw a little fps improvement Both were run on clean installations.
