--- Comment #1 from Stefan Dösinger stefandoesinger@gmx.at 2011-08-01 18:09:18 CDT --- This patch shouldn't cause performance regressions any more, and I don't see any difference in StarCraft 2. What kernel are you using? I noticed that 2.6.39 had a performance regression vs 2.6.38 that is fixed in 3.0 already. Maybe this performance regression is triggered by the driver when dynamic VBOs are used.
