Always keep my drivers up to date, even tried different versions etc and I've cleaned any old drivers. Tried re:installing game, change settings, browse web for similar problems but no success.
System speccs:
Gigabyte p67A-D3-B3
i5-2500k
Corsair SSD Force 3 Series 120GB
Asus GeForce GTX 580 1536MB Matrix
As this issue has been on going in Alpha as well i added both Alpha and the current Beta Appdata folders:
