I was scoring maximum average as low as 25 fps with my Sapphire RX460 Nitro 4gb yielding a score of 1072 points, using Windows 8.1 OS. I just upgraded to Windows 10 Pro. Same overclock as before, i just hit 44 fps average, yielding above 1840 points. I mean this is hilarious. I was expecting an improvement but this is like double performance. Can anyone explain? Was my previous OS that corrupt or what?
