[quote]I would prefer if people could verify this by simply noting GPU usage in low FPS areas to somewhat confirm my theory, Ive noticed much higher GPU usage on a lower preset Post BL than I did Pre BL and lighting is the only major graphical change to take place.[/quote] No this ain't it... I don't even get more than 80% GPU usage or 40% CPU usage... CPU usage do get better if the "force_enable_multi_threaded_render_submit" cvar key, also fps gets a little better, but still not as good as before. Graphic settings do barely make a difference, you can read a lot of people with the same behavior too, here and old post about this problem. 100%, 80%, 50% doesn't matter neither.
