[Help] Slow Motion?

I am experienceing a slow motion effect and like 5-10 fps. It is totally un-playable. During the beta this happened, and I fixed it by joining local servers, but I dont know....

trying freeing up some of your disk drive space see if this helps with how your game quality is running.

Also there is a program that allows you to lower your process levels which will allow you to run your game faster.

Game Booster | Fast Game Accelerator | Free Accelerator

I use this so it can be trusted but use at your own risk.
