Fortnite prettu much all low and csgos all high (if i put all low my fps is around 60 instead of current 150) current mobo is H-Joshua-H61-uATX and 1x8gb ram. I got 2 monitor setup and even if i remove 2nd one it doesnt make a difference
Well it may be due to the game files being updated and added to over the 2 years. You can try to play around with the Nvidia control panel settings. Use task manager and see if there is anything taking up resources while gaming.
