Got the Operation Arrowhead demo installed, and after several different settings and an updated NVIDIA driver, the demo hardly runs it's so stuttery, and I was getting strange multicolored vegetation before the new driver. I tried Windowed mode and that helpd slightly, but is still unplayable. Tried it on the lowest settings possible and it still stutters bad.
I suspect my rig isn't up to the task, but seeing some others rigs, mine should be okay or is it?...
