Im having really bad performance on UE5

I recently installed an NVME and reinstalled everything on it. Everything works fine apart from unreal. I downloaded every version of unreal (5.2 onward) but i just seem to have generally bad performance even on things like blueprints, it stutters and stuff at first i thought its the nvme but at the same time why is it only UE5 thats acting up, on my previous SSD i had no troubles. ALSO when i try to test things out in the pop out preview window my frames are like 5fps but when i do it in the editor its normal (around 100+ on epic settings in third person map template). If you have any solutions please drop them below
