Hi everyone,

I'm not sure if this is a known issue or an individual issue, so I thought I'd post here.

My machine's specs are:

-GTX 670 video card
-I5 - 2550k processor
-8 gb memory

Benchmark is a little over 11k.

The game runs flawlessly on the maximum settings at 60 fps in most areas, but after about an hour, the screen goes black for a couple of seconds and my FPS drops to 20 for about 10 minutes.

This was during beta phase 4.

Does anyone know how to fix this or is this a known problem they're working on?
