Simple GLSL Shaders are really slow on MacBook Pro 13"

Question

I have just get a new MacBook Pro 13 (i7 with Intel HD3000). I know that intel graphics card are not a beast but the performance I getting with simple glsl fragment shaders are really bad.
I have some video post processing shader in glsl in an application I have developed for mac. On my old MacBook Pro 15" (with nvidia 8600M) the performance was not perfect but I got 32-60 fps depending on the shaders.. with the new one I have 1-2 fps when shaders are on i.e. with a gaussian filter the perfomance drops to 8fps, with a little bit complex fragment shader performance drops to 1-2 fps.
My question is if is this a known problem due a driver implementation? or if is it the expected performance of the intel HD 3000 graphics card?
I really like MacOSX for work and develop but if this doesn't have a solution, I will have to return my mac and see other alternatives, It is impossible to develop any simple OpenGL application with this card .
Thank you,
Rafa.

Answer 1

I have just tested the same application on the mac with windows 7. The performance is a little bit better with shaders but bad in general.
Performance on MacOSX:
Video only: 60 fps
Video+Shader: 2 fps
Performance on Windows:
Video only: 16 fps
Video+Shader: 14 fps
So my guess is that on macosx there is a driver issue with the card.
Thoughts?
Thank you,
