So I have had my current system for about 10 months and I am experiencing unstable frame rates lower then what I should be getting with the settings I have in the applications. The main game I am experiencing this in; as it is the main game that I have been playing since the issue has presented, is League of Legends. Before the issue started showing I would be getting 190-210 fps on high settings stably, now I am only getting a max of 64 fps but it consistently goes between 22-55 fps which is really jarring. My system is running a Ryzen 5 2600 and a RX 570. I have recently replaced my motherboard but it was doing the issue with the old one and is still doing it with the new motherboard. I am unsure as to why it is doing this now as the settings have not been changed since I got the PC. I also have been having issues with programs taking 10x longer to start then they used to before the issue started presenting.
