Haven't had any issues with the client like this before. The client loads as normal/fast and I can login fine. However, lag is so bad it takes me 2 minutes just to exit out of the welcome screen or whatever. Then from there it takes me minutes just to move.

I deleted Java then reinstalled and rebooted. Also deleted clients and redownloaded multiple times. No luck. Game works perfectly fine on my phone. My computer and Internet seem to be running optimal. Have had no other issues with my PC outside of this. I was playing Rev perfectly fine before this, didn't change anything with my PC and suddenly this happened.
