It probably should... 3-5 seconds sounds _BAD_ alright, but it's nowhere near playable on my Athlon 1400 MHz either (without hardware acceleration). > > Also, I'm just now getting into X (been using FreeBSD since 1.01 but always > as a server), and I was wondering how I can tell if my video card's > hardware features are even being utilized? I think the command you are looking for is ``glxinfo''. If you are using a stock XFree86 installation that comes with FreeBSD, your 3D hardware acceleration chip is most likely not being used. The Viper V550 uses an NVIDIA TNT chipset, as far as I know, and they aren't supported by DRI. You could however check out Utah-GLX, http://utah-glx.sourceforge.net, I think they support the TNT chipsets... The best solution, however, would be to wait for NVIDIA to release the FreeBSD native binary drivers, which they'll hopefully do soon. Matthew N. Dodd has been working on getting FreeBSD NVIDIA drivers and you may see his work so far at ftp://ftp.jurai.net/users/winter/nvidia (although those drivers don't provide any 3D acceleration, yet! NVIDIA are busy finetuning the drivers for their upcoming GeForce4 chipset). > > My current config (don't laugh): > > K6-2-300 > 96MB RAM > Viper V550 w/16MB The K6 line of CPU's are known to be slow at doing FPU operations, and I guess that 3D rendering involves a lot of FPU calculations... I think OpenGL was more meant to be an abstraction layer between the 3D hardware and the application rather than a software based rendering suite. > > I have tried running with everything turned off, i.e. no walls, halos, etc. > and even with no sound and at 320x200, nothing helps.
