Very Strange Problem, when i have 3DM2 12MB, i Play Quake 3 at 1024x768 with 70FPS+ at all Maxed Settings with FV 4.6 Windows XP and GeForce 4 MX 400 AGP, Try Install Wicked GL and Copy opengl32.dll to Directory, where game execuatable is.
Then Select in Game OpenGL Mode. (Try 640x480 for first time)

Seems Like Your Problems comes, cause u have already Accelerated Integrated Video Chip, Try Using with any PCI VGA if opengl32.dll not working!

Good Luck

I Play on Pentium 200 MMX at 1024x768x16 Need For Speed Hot Pursuit with EvilKing (12MB Single Sided Memory PCB), all tweaks:http://www.youtube.com/watch?v=CT_E2y5d0eY

With Voodoo2 GE Win9x Driver, in Driver Tab, just Set "Force Mipmap, and Tripple Buffering", anyway first and second options in "Advanced" Setting of V2 1000

Freezes?! Looks Like Hardware Problem, i have SkyMagic, and all works so nice: http://www.youtube.com/watch?v=hdAanVCnLvw
