Updated fine. Unfortunately, I'm unlucky regarding frame rate. Under the test conditions (lightly loaded, sliders default, EM=0, all boxes disabled) my rate went up (106 to 121), but under heavy load conditions (CraterMA tank area in heavy forest with zoom), using my normal settings of nearly everything maxed, I actually lost quite a bit of frame rate in Beta 5. In deep forest my frame rate went from playable (can't remember, but say about 20 or 25) down to an unplayable 12. (Of course my PC is ancient.)
