Connecting Nodes in Blueprint Causes Lag

I’m using an NZXT water pump and their software is indicating around 35C for the CPU. I’m not sure if that’s accurate or if that’s good or bad.

I got the idea to open some old saves of the project. I sorted by date and one by one I kept opening the project at a later save date until I encountered the issue. The issue seems to happen after having changed from directx12 to directx11. The game would crash every few seconds in directx12 which is why I switched. The game never crashes in directx11.

That is all I did and now the lag is entirely gone. Even with it set to directx11 still. (For now at least.) So I really didn’t do anything. Again, just open some old saves. I don’t really no why the lag is gone now. I was hoping for an exact solution, but all I can really do is explain that I did what I’ve mentioned and now it’s gone for some reason.
