It makes it unplayable. At busy times it's just as bad as when the servers are pretty much empty and it's the same in every area. For 2-3 seconds my fps is fine (60-80) and then it starts skipping (20-15-2-4 etc, sometimes it freezes for a second) for about 4 seconds and so on.

I tried:
- Updating all my drivers
- Reinstalling my drivers
- Every different graphic setting under the sun
- Applied thermal paste to my processor
- Running other games, they work fine
- I checked whether my system can run this game and it should be more than ok

I'm currently at the point where I'm about to reinstal windows to see if that fixes it but you'll understand I'd rather not. Any other game I can run fine though, on high graphics.

What can I do to fix this?
