Yes it seems I am having this exact issue, I do not know what is causing it and it is quite frustrating. Especially since as you can see it makes it almost impossible to see what my gunner is aiming at past 400m. Any manual fix for this would be appreciated.

Currently I have windows 7-64 bit , gtx 560 ti and a I3-2100 cpu.

Ah, thank you for that NodUnit.
