When I start any game like MW3, BO2 , my Physical memory usage goes up to 50%.. My RAM is 4GB..
This wasn't happening to me before.. It started getting like this 2 days ago.. Yesterday I ran a registry clean and it was ok.. Game wasn't lagging, but today it's lagging again..
I used CCleaner, Glary Utilites, MalwareBytes, scanned with AV.. but nothing is happening
