In terms of the graphics upgrade, the re-engineered code requires Aero and is offloading work to the GPU. I switched to my on board GPU as this had better performance with Aero than my Radeon 7450. However, in doing so, the overall CPU usage became elevated. It did show a slight improvement on the performance meters, but no way close what I get with 7.5. In 7.5, I can normally work on quite complex projects at 24/96 without issue. I already did a clean install… total hassle and didn’t change a thing to be fair.
