FPS probs

Hope i’m in the right spot for this. I’ll keep it short and to the point. I’m running off a HP Omen notebook but im having some real FPS problems. The weird part is, it even happens when i’m not in a crowded place or in a big fight, which is throwing me off(and of course it happens in fights too). I’ve tried nerfing settings, going to windowed, reducing the resolution to 40hz, but I can’t seem to find a fix. Was hoping someone might have an answer. To give an idea, I can run DA: Inquisition on high pretty much FPS lag free.

current specs: Nvidia gtx 960m
