Greetings!
So, I have kind of a weird problem with my PC, have had it for about a year or so. After the PC has been off for a little while and I start it up the performance is low when I start up a game, Battlefield 4, GTA V, CS:GO.... But after I shut the game(s) down and restart the PC the problem is gone. For instance when I first start Battlefield 4 the FPS is like 50-60~ and the screen is tearing, after restarting the FPS is well above 100 and the game runs smooth. Sometimes I have to restart several times for the performance to be "normal".
I have tried running MemTest86, which resulted fine, updated motherboard and GPU BIOS, installed all the newest drivers that are available, reformatted Widows several times, tried both Win 7, 8/8.1 and 10.
So I'm hoping some of you maybe have a clue to what is wrong/what I could try to do/test.
Setup: CPU: Intel Core i7-4770k GPU: Gainward GeForce GTX 780 Storage: Intel 335 Series 240GB Memory: Kingstone 8GB DDR Motherboard: Asus Z-87 Deluxe (Hope I posted this in the right category)
