After days of googling and a lot of hard work i give up. Windows 10 is still in alpha stage thats why its a free upgrade. My primary use of a pc is to play games but if windows 10 cant provide it then whats the use of using it. A game getting constant 60 fps in windows 8.1 and below is barely reaching 60 fps in windows 10.. Frankly speaking Microsoft is dead since their last good piece of work which was windows 7. Nevertheless, having found no solution to the issue mentioned above, i have decided to go back to win 8.1 And in the end all i can say is SCREW YOU MICROSOFT.
