--- Comment #10 from Alexey Loukianov mooroon2@mail.ru 2011-09-15 17:24:42 CDT --- Hi, Henri.
HW: GTS-250 a.k.a. GeForce 9800 a.k.a. GeForce 8800, VRAM 1024MB, CPU AMD Phenom(tm) II X4 955 Processor, RAM 6Gb.
FBO is faster, I agree. Thing is that backbuffer ORM of now much slower than it was earlier :(. I have no problems with MSAA+FBO nowdays and you have done a very cool job implementing new MSAA support into Wine. Trouble is that I can't get any kind of "transparency AA" in HL2+Wine nowdays, and the only way it was to handle prior to Wine 1.3.27 were to use msaa=enabled + orm=bb + forcing SSAAx2+MSAAx4 in driver CP.
With new Wine's MSAA implementation it seems that speed with orm=bb had regressed severely on the hw config I have at home. Nowdays I have to stick with orm=fbo + bad quality of picture or to use something like Wine 1.3.4 + orm=bb + msaa=enabled + AA=SSAAx4+MSAAx4 forced through driver CP to get the best quality that is available through Wine's d3d emulation.
