Basically, I have a GTX 1060 6GB which apparently is supposed to be a quite good card, and my Unigine Heaven Benchmarking stays at a stuttery 65 FPS at max settings, but every time I play a game, even on Medium settings on Destiny 2 for example, my FPS is very inconsistent. Sometimes it will run at a Fluid 60-70 FPS on Highest, then other times it will run at 20 FPS on Medium. It also translates into other games. Games like The Binding of Isaac: Rebirth, a very un-graphic intensive game, will stutter and freeze up constantly. I have an AMD Athlon II 645 Processor at 3.10 GHz, along with 8 GB of gaming RAM as well. I am on Windows 7. I am getting tired of being unable to play games because even on Medium they are a stuttery and laggy mess. Please help me.
