And welcome the lovely world of PC's! Where sometimes one little driver somewhere in some obscure location will cause you grief Can't really say I've run into any lag spikes that ive noticed with just my eyes and pretty much always 50-60fps from when I have but the odd and I do mean odd invisible wall has occurred.. Once with a horde and the other when just wondering about but I haven't moved on from the .10 version. Running in 64bit, an I73820, gtx670, 16gb ram.
