Here’s the DLL that needs to be replaced. It turns off vertex caching, so I can’t guarantee it won’t cause other issues, but it will slow things down. Actually, I won’t guarantee anything, including it not causing a nuclear explosion, so use it at your won risk.
It only effects the editor,so you can’t run anything outside the editor until/if someone fixes it.
It needs to be unzipped and put here, back up the existing file of the same name first.
