Hi all!
I'm running Gentoo Linux on my AMD64 laptop and my drivers are:
x11-drivers/ati-drivers-8.20.8
However, I'm experiencing som wierd behaviour. I think i've narrowed it
down to doing exponential-function in the vertex-shader. This simply
doesn't work. This again means that all my sin-/cos-/tan-/etc-functions
also are broken. Curiously enough, exp() seems to function in the pixel
shader.
Running my code on NVIDIA cards I get the correct result. Also, I
haven't been able to test on Windows, as I don't have it.
Futhermore, I'm trying to use the OpenGL ARB_occlusion_query extension.
I think I've implemented it correct, but I keep getting the same number
of samples back from the query whether the drawn object is visible or not.
Could these problems be driver issues? Has anyone else experienced
similar things?
Any help would be appreciated
