Zbuffer

i have a gforce4mx but the same problem have with G400…this is the problem: when in opengl some pfmt doesn’t work correctly… i have problem with Z-Buffer, for example in NVidia setting depth buffer to 32 bit , 32 bit color depth and 0 about stencil buffer the Zbuffer doesn’t work corectly, but with the same scene when i use the pfmt depth buffer 24 bit , 32 bit color depth and 0 about stencil all go OK!!! WHY??? The same with G400!!!

Any IDEA?

EDIT : … cross post

Most old(non NV3x) NVidia cards have combined depthstencil 24/8 bit. I’m not shure if they have a 32 bit depth.
