I have a problem with fps-drops in overwatch on my Lenovo IdeaCentre AIO Y910 (27"). It only started recently, but I can't recall exactly when. The problem is that overwatch used to run at a pretty steady 144 fps on ultra, now it doesn't go over 60 and often drops to below 10 for extended periods of time, often up towards two minutes, on the lowest settings. the specs on my pc are as follows: Processor: Intel Core i5-6400, ram: SK Hynix 8G, GPU: NVIDIA GeForce GTX 1070.
