Hi, "I try to get definitive information about off-screen support using AMD_GPU_association for consumer cards."
AMD_gpu_association can ONLY render into offscreen FBOs, not into windows. You are supposed to blit the result of a rendering (using an 'associated context') into a window (bound to a second, unassociated context) by wglBlitContextFramebufferAMD(). With the current means of equalizer, we'd need to create 2 pipes for each GPU, one associated, rendering into the offscreen FBO and one unassociated, rendering into the window. Additionally, there needs to be another compound, blitting from FBO into the window, using wglBlitContextFramebufferAMD. But I don't like this notion, since this would mean, the needed config would be hardware-dependent. It should be transparent to the user, if there are Quadro's or ATI's in his machine.
