I’ve took a screenshot of the task manager during this happening:
A: Im in unreal engine and I have this alternating lag that makes me vary between 60 and 25 fps every seconds
B: I go on an other windows, yet the spike continue to exist
C: I go back to unreal engine and it disappeared completely
D: I’m in UE, I havent move the scene at all, just waiting and the intermittent lag happen from nowhere.
Yet when I retried the experiment looking at the app used, nothing seems unusual
