I'm aware of two perfomance bottlenecks in the driver. Number one is that it always uses synchronous DMA. I have asynchronous DMA working just fine under DirectFB but it should probably be tested more with XFree86 before going to cvs. Number two is the TC2_MAGIC bit. It really hurts the single texturing case and even dual texturing gains ~1 fps (in q3) with that bit turned off. Even with those two changes the Windows drivers are still quite a bit faster :( > Notes: Reliable, looks great. UT suffered from lots of software fallback. Any idea what fallbacks? ut2k4 demo was actually playable on my G400 if I disabled the texenv extensions. We probably need a config option for that. ut2k3 demo always used projective multi texturing despite what settings I tweaked so I couldn't get decent performance out of it. -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 -- _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
