I also made a test on Radeon 5890 64 bit Vista. Also wrong results. However its bit different than on NVIidia because it looks like base texture does not get read at all. I really doubt this case is simply an issue with mixing CubeMap / Tex2D fetches. I suspect there are other factors involved (like fact that cube map is rendered on the fly) but do not have time to trace it...

That is good result. I guess this points to be really a driver issue. Thanks for finding a time to test this!

I've tried different factors and it made a change in the output. I do get: Warning: detected OpenGL error 'invalid operation' at After Renderer::compile on both machines. jp Trajce Nikolov wrote: Here is attached code ...
