Reinstall the drivers, they sometimes cause something to go funny, like for me, the 12.11 beta drivers caused Battlefield 3 textures to sometimes disappear. Erased and reinstalled.. problem solved.
Tell us what your rig is, I'm not sure what you mean by high end
The drivers for what exactly? .. And the rig is as stated below
MOBO: Z77 OC Formula ASRock
CPU: i5 3570K (OC'd to 4.3Ghz)
RAM: 8GB (Cannot remember actual name.. Decent stuff though)
GPU: GTX 680
HDD: 2TB barracuda
HDD2: OCZ 128GB Vertex 4
PSU: Seagate (Something or rather) 650W if I remember correctly
Other hardware include:
Corsair H100 CPU Cooler
.. That's all I can remember off thetop of my head.. Excuse me if I missed any..
