Example: Matrox card's have a very nice driver for 3.3.x that can't be just plugged into XF 4.x without modification. So far I have not heard someone putting the hw driver into the new architecture.

Games are the most catchy demos for a general audience. We have such a good Linux emulation and the differences under the hood of XFree86 are not that distant. I really hated it that Linux was perceived as that great gaming/multimedia platform and FreeBSD not. So it was a must to crank out some demos quickly that show that if it runs under Linux it will run under FreeBSD with few modifications too. BTW I was very happy to read the recent Loki/BSDI press release that supports my opinion. The 3d page is far away from the 3d portal I hoped to realize there. I sit on a huge pile of half finished ideas, links and snippets I never found time to put up there. It is also a bit problematic that I have only access to nvidia cards. So I depend on feedback from Matrox, 3dfx etc users. And that feedback is rare. On the other hand it was better than nothing. Last year it was a rather esoteric topic among BSD users, now many people seem to poke at that stuff. I hope the situation will improve now as hobby and job align again. I need to do a lot of 3d vizualization of DNA and protein structures under the XFree86/nvidia combo in the near future, so I am likely to be challenged by the same problems like you do. (The VTK 2nd edition manual lies here on my desk too.. :) If you have some 3d related information that you want to publish on that web page I will integrate it. Serious stuff is as welcome, as fun one. After all most BSD users know that BSD is a superb working horse for serious tasks. What needs a bit of propaganda is that it is also a nice multimedia system. > Well, the question stands whether a GeForce would give recognizably > more than the current TNT2.

That would have given some hints, if your driver was a bottleneck. I can offer you to run a VTK test app on the K7-700/GeForce here.
