Ok so recently (2 days ago)i reinstalled my OS(windows 10 64 bit) but a weird and very very very frustrating issue has occurred,i am experiencing constant input lag inside the OS and inside games, my main game is CSGO and that requires ZERO lag of any sort especially input lag, game DVR is disables,infact that was the first thing i did before i even noticed the input lag,what else could be causing this issue? any ideas on how to fix it?Any help would be very much appreciated as at the moment i cant play CSGO and its driving me insane.
