--- Comment #11 from Jonathan Strander mblackwell1024@gmail.com 2012-09-05 23:41:23 CDT --- Continued checking up to 1.5.12. Slow overall fps is still an issue. Disabling SSAO (the most intensive effect besides Ubersampling) nets a 1-5fps increase. Disabling AA gives an additional 1fps depending on the scene. The highest FPS I achieved at 1920x1080 was 35fps but only in a single location/viewpoint. Otherwise the average was still in the twenties.
The only way to get a framerate close to what should have been experienced was to drop down to resolutions like 800x600, and this still gave overall low performance in most scenes. However in the higher fps scene mentioned above the framerate was in the 40's rather than the 30's.
