hey, personally i haven't experienced such game skips, but im using non beta drivers, simply because the latest nvidia drivers are messing up with my win 8 installation. try downgrading to non beta and test it out.
i'm using the 320.49 final release but custom installed only the video drivers and physx( for some reason gforce experience and hdaudio were messing my windows , BSOD)
