Oni and OpenGL

I have a Duron 600, 64mb SDRAM, OpenGL 117, and a Stealth III S540 Xtreme card. When I first installed Oni, and switched to app on, I noticed everything was fine, menu and all, until I got to playing it. The textures are all distorted or transparent, sometimes code is printed on objects, Konoko’s only solid, fully textured part is her head! I would try to update drivers if my internet connection worked on !!–MY–!! computer, so what can I do?


PS got Win 98 (Oni does the same on ME)
