AMD Radeon 7950 - GLSL is 4.3 but OpenGL API is only 4.2?
Apologies if this is in the incorrect spot.
I'd like to try out the new compute shaders, and I'm trying to figure out if my card can handle it. It's a Radeon 7950 powercolor with the latest catalyst driver (13.9).
I was trying to find a demo program to test it out, and tried GLSL Hacker. In the log file it has this:

It won't run the compute shaders, presumably because of the 4.2 context, even though GLSL is 4.3.
Does anyone know if this card can run those shaders? Whats the difference between API version and GLSL?
