Hello! I did finally manage to fix it. For me at least it was something stupid. It was a really, really big light that wasn’t even lighting anything. It was half baked but it still ended up causing massive issues. Check if that is the case for you too. If you can not find something like that, try to check the gpu visualizer. I think it was Ctrl + Shift + “,”. Maybe it will show what’s too slow there. Either way, I think it is to do with the GPU being overloaded. Hope this helps!
