Has anyone experienced the issue where your FPS drops a significant amount after leaving the game running in taskbar mode for a prolonged period of time (eg: overnight fishing/dummy training, etc)?

My FPS is usually around 120-165 in AMD Super Res-Quality but always drops to 60-80 overnight. Is there a fix/solution for this issue without having to restart the game?
