--- Comment #5 from Danyil Bohdan vernetzt@mail.ua 2013-04-03 11:44:38 CDT --- I ran 3DMark2001 SE on a work machine today, a desktop PC with an Nvidia GeForce GTS 250 graphics card running Linux Mint 13 LTS with kernel 3.2.0-39-generic, X.Org Server 1.11.3 and nouveau drivers (reporting as "Gallium 0.4 on NVCF"). The difference in performance is considerably smaller but it is still there. Due to the lack of time I was only able to perform a single trial for each version.
The scores were as follows:
Wine 1.4.1: 10664 Wine 1.5.27: 9375
I'm not sure when and if I'll be able to test each patch version for this regression, though.
