If the shader code, in my engines running GLSL quite easily. you use features that are not dominated the GPU, then the shaders are emulated on the CPU be they of course NV, if you do not use hardware-assisted features.
I currently attend a computer graphics module at university, now we had to implement GLSL shaders in some we use to program in C + + and OpenGL, the strange thing is that the shaders on NV boards run smoothly. If, however, the program runs on a PC with AMD GPU, the GPU acceleration works at all and it runs to 100% to the CPU - which naturally results in an unplayable FPS, now I have no idea whether the problem is known or if the shader is something wrong. Posted otherwise the shader code in a moment, the problem occurs on two completely different computers, both with AMD graphics cards even a 5750 and even a 5850.

You were right, shader code revised again, now it works, i was worried at first been a driver problem, but now flüppts perfect!
