TY for your feedback. I had a chance to test them last night, particularly with DAI. On my Windows 7 partition, I noticed that the performance did not change at all between 344.75 and these new ones. I then went and updated on the Windows 8.1 side. I noticed that the framerate in some areas didn't really improve at all, however the gameplay does seem smoother overall, so that it itself is an improvement. I will also test some benchies, but overall they appear to be a bit better..
