I'm use Mesa 7.0.1 mainly because performance is the best and not have glitches in some cases like newer, but tried wine-0.9.59 with 7.02 and 7.0.3 also. My card is HIS 9250 128MB/128bit (1002:5960 17af:2020). This r200 performance issues started with this patch:
http://gitweb.freedesktop.org/?p=mesa/mesa.git;a=commit;h=e279a0a076b7a3c8d6...
I'm atached some screenshots with or w/o ps enabled using Mesa 7.0.3 for this to show, clean .wine directory (just winecfg and then install 3DMark) default driver setup and default 3DMark2001 setup (just used 800x600 for windowed screenshoots, checked 'emulate a virtual desktop' in winecfg). All these primers work good in previous versions of wine (except with properly moving water (river and sea) and portals showing in DS2 (that work good when i add once again 'mat[12] = mat[8]; mat[13] = mat[9];' in utils.c) i know that is another thing, but helps), but not working good with wine-0.9.59 with ps enabled. Exeption from this is Painkiller which starting only with disabled ps, registy key DisabledExtensions GL_ATI_fragment_shaders also not help and that disabled one textured unit in driver is needed from time to time (not always), also this happens in all 7.0.x Mesas.

NOTE: i mainly use extern libtxc_dxtn.so (for this tests w or w/o - same results), because some native games Regnum Online, Quake4... needs it to working properly, also Indiana Jones: Emperors Tomb with wine even refuses to start without it.
I'm registered to bugzilla, but everytime it says that my password is not good (maybe my firewall issues?), because of that i use mailists to inform devs about bugs (i have many to fill like SeriousSam FE/SE resolution regression, same game engine: SE starts(but crash on exit), FE not even start, SE crash when resolution changes and in both games this work good with 0.9.45 and older like .39, .29... Icculus installers for these games work good, but have other issues. All this is tested on: same card, same X server, same distro, same driver, same Mesa, etc:).
