He uses Qt for everything else, like mapping windows from the windowing 
system, input event management, etc. Also, note I said "design with OpenGL in 
mind", not "design with OpenGL". So what needs changing is the way of 
thinking, not necessarily the code itself. Using OpenGL and repainting 
everything from scratch with a lot of CPU calculation is not going to help.

The point is that if you need the performance of graphics, you need to use the 
GPU the way the GPU is designed. Reduce your CPU work and use more retained 
settings across frames.
