Z-fighting issues

[MHaggag]

I am using EQUAL depth test mode when rendering and this might casue soem problems allthough no other ATI card has had problem.

I think this is becuase of ATI Vista drivers I am afraid ....

Would a depth func of GL_LEQUAL together with polygon offset work? That's what I use in my code to work on this card/driver combo, since GL_EQUAL causes z-fighting. Out of one of my apps:

Code: (Select All)

glEnable(GL_POLYGON_OFFSET_FACTOR);
glPolygonOffset(1, 1);
glEnable(GL_BLEND);
glBlendFunc(GL_ONE, GL_ONE);
glDepthFunc(GL_LEQUAL);
