I have a 1080 TI and a i7-7700k. I have bought this pc last summer. 2 days ago my gpu starded to do not work properly. In OC i have in World of Tanks 20 fps(normaly i have about 100-120 on 2k resolution and maximum settings). When i look in Task Manager i sow rhat my gpu is using just 5-10% of it s power(normaly is about 75-80%). Then i look in graphics engine and the paremetrees were normal (1100 mhz memory clock and 1700 g[u boost clock). Could you guys help me? P.S When i try to run the game with my integrated graphics processor still have 20 fps.
