Texture problem with ATI Mobility Radeon 5730

Hi, 

We have developed an application based on OpenScenegraph and it works fine on Nvidia cards. I am trying to use the application with the ATI Mobility Radeon 5730 and all the textures of the 3D models are being messed up, the lights also.

Any ideas? 

Thanks

I'm just guessing here, but if the renderer is based on OpenGL and it uses GLSL shaders you have to take into account that the ATI drivers are much more strict about GLSL compilation. When a function expects a float2 and you pass a float4 expecting automatic conversion, it just won't allow that. So, Nvidia drivers do the automatic conversion and just issue warnings, ATI issues them as errors and refuses to compile them hence the bad textures & lights.

How about reinstall the drive for your display card?
