In the nvidia panel (which is in my language) there was this thing called "triple saving in mid memory" (I translated it to english just now) and since its the only phrase that starts with the word triple Im guesing thats it xD. So anyways it was turned off already. As for the DxDiag its super big to post so Ill just post the system information and the display devices part (except if you need more then I'll post it all). Im sry for this long post please tell me if you need more
