So, when im playing a game, for a few minutes it seems fine. No lags. But after some time, it randomly starts lagging and i get just about 5-10 fps. I checked the Memory usage, and my GPU usage, and the memory was at 80% and the GPU was at a 100%. I have 8 GB of DDR4 2133mhz ram, and a GeForce GTX 750ti graphics card. This happens to all of my games, and like last week it was perfectly normal. I dont know what causes this, but its pretty annoying. If you know any solutions, please write them down. I cant play like that. Thank you.
