I’ve made tests that You proposed with no luck. I’ve removed widget in question from the level completely. Now this level is completely blank, just default blackness and it didn’t affect performance either. Screenshot:

To sum up: On totally empty level FPS is 25. Performance is limited by CPU rendering thread. There is nothing to render. Display resolution is set to 1920x1080 fullscreen. If I change it to 800x600 fullscreen FPS is 75. Game was build in Windows 32 mode, it is runned on Windows 7, 64 bits.
