This is the best driver for me in thr 3xx.xx series... I was having FPS drops with the previous drivers on Source games (CS:GO, Dota2) OR BF3. If ones FPS was good, the others were bad. But with this driver both engines runs well, Borderlands also runs well too. So I'm quite happy with these. EDIT: But I have to ask this: I'm using a Optimus powered ASUS notebook, normally on desktop device should switch to the Intel HD chip and there is an indicator for the switch which goes blue when Intel in use and it goes white when nVIDIA kicks in... This stays on Intel all the time... Any one experiencing this?
