Hey Guys! I´ve searched quite a bit to find something described similar to my Problem, but wasn´t succesfull with that. So i´m gonna try here: I´ve got varying performance changing by a second. Spawning in Area 18 for example, there are lightbands left an right of the Elevator door scrolling black and white. This Scrolling isn´t constant, but slows down and speeds up. Same with walking or running. Fast slow Fast slow. It´s not just graphics, but also the sound for the steps i make match the changing in speed. Even an Elevator in the Hangar slows down and speeds up the same way. Seems that FPS flip up and down constantly, but never freeze or something like that. 20-45-22-37-21 and so on. I get this in Hangar, AC, PU or SM - no difference. Very High or low settings - no difference. Also i´ve tried all kinds of settings of my GPU. I´m no Pro, so maybe i´m gonna make a fool of myself with this Error description, but maybe someone can tell me what to tweak to fix this? Thanks in advance!
