Hi,
So the other day I was using Unreal 4 perfectly fine when suddenly I open up my project and everything ran slowly and even moving the mouse too fast caused Unreal to crash. This seems strange to me because not only was everything working fine the day before, but the project is simply meshes dropped into the scene with no blueprints or anything. Upon searching for a solution on the internet I see others with a similar problem but no actual suggestions on how to fix it.
