A quick test with a second xserver in 32 bpp mode (the glx driver accelerates only for 15 and 16 bpp modes and I was too lazy to save my existing X sessions) using startx -- :1 -bpp 32 ran the teapot demo at least 6 times slower. Quite a difference. (and this with Mesa 3.0, unoptimized RIVA drivers and present non-DRI glx) Some general remarks: All QDraw demos except 'varray' (nothing seems to happen) run fine, alas they don't resize if I maximize the window. Maybe they don't get the event. I like the triangle demo most, due to the lighting effects. One has to have a look at the sources to understand what keys are used. That example source is pleasing to the eye as well, it seems to be a nice C++ API indeed. As my NT box at work has been UNIX-ified with Cygwin long ago, and a Matrox G200 is present, I will definitly give it a try under NT as well. The crazy idea that haunted me was to abuse QDraw for getting DirectX stuff working under X11. A DirectX to QDraw bridge might be easier to realize than a DirectX to OpenGL one. But it seems that the Wine folks already do some DirectX to Mesa mapping: http://www.winehq.com/source/graphics/ It seems to run a lot of games already, according to this link: http://www.linuxgames.com/wine/ Regards, Marc To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
