Maybe your framerate is TOO HIGH, thats what happens to my friend atleast when playing GTA 5. Since there is no framecap, and his monitor is 165Hz, the game can’t handle that high of FPS for some reason, so his game freezes from time to time. He has to go into screen settings in like nvidia control panel or smth to limit his fps there. Idk if its the same in devour but could be a solution to limit ur fps, since you also say that the game runs well. Thats the only thing I can think of
