Hey guys, i have been experiencing lag spikes in certain games(middle earth shadow of mordor, farcry 4, watchdogs and assassins creed unity)which were not there earlier. The lag after starting continues to exist and therefore results in a massive drop of fps(from somewhere around 55 to 35 or even below. These lag issues didn't exist earlier and the games used to run very smooth for me. Please do help me guys i have no clue about what to do.
