Not quite true, KindDragon.
I'm using INTZ on XP without any problem (8800GTS/GTX/GT, 8500...). I'm also using RAWZ on XP (7900).
Could you please provide some detail on this? I'm trying to use INTZ on WinXP (8600 with latest drivers) and so far I got the scene rendered through INTZ depth buffer. However, texture fetches always return the value I use for clearing the depth buffer in all channels. Is there some trick that I am missing? Basically, I do the following:
1. Create a texture with INTZ fourcc.
2. Get its mip 0 and set it as depth-stencil surface.
3. Clear depth buffer.
4. Render.
5. Unset the intz surface and set the master texture on a shader.
Any ideas?
