So a few days ago a problems started appearing. I will play a game, and the game runs really smooth, at like 70-80 FPS on very high settings, but after a few mins it goes to like 20 FPS!! and if I restart my computer, it will be the same, it will work smoothly for a few min, and after that it will start to stutter and play at like 20 FPS. this happend to me in every game. in war thunder, in wolfstien, in the witcher 2. I start the computer, I play the game, it runs smoothly for a few mins, and then I am forced to lower the settings greatly because of the FPS drop. I used to play war thunder on movie settings, and the FPS was on average 60+ in battles. now its 20-30 if I use these settings. my system specs are: Intel Core i5 4570 3.2Ghz (3.6Ghz Turbo) LGA1150 Tray Intel Original LGA1155-1150 ליבת נחושת - עד 95W (ליבת נחושת means Copper core-till 95W) Gigabyte GA-B85M-HD3 for 1150 Silverstone Presicion PS08 USB3 + FSP 500W Crucial 8GB DDR3 1600Mhz 1.5V CL11 Gigabyte Geforce GTX760 2GB RETAIL Seagate Barracuda 7200.14 1TB SATA3 LG DVD-RW x22 Dual Layer Sata Black Thanks in advance!
