Hi, I'm running a VM with Windows XP on PD7, I have a MBP 15" HD6750 with Lion. I migrated this VM from a MBP 13" 9400m, and I was using it to do simple projects on GLSL programming using Visual Studio. Since I migrated the VM to my new computer, it's stuck with the GDI renderer (which supports OpenGL 1.1) and I can't compile shaders anymore. I've disabled the automatic graphics switching, which forces OS X to use the HD6750 and tried to reinstall the Parallels Tools, but that didn't work. I've set the optimization options to the best performance of the VM, and that didn't work either. I've searched the forums and the net, but I can't find a way to make the VM to go back to the OpenGL 2.1 renderer, does anyone have an idea?? Thanks!!!
