Hey, I've been having some pretty random FPS drops over the past couple of months that seem to have come out of nowhere. I play on max setting, 1920x1080, capped at 144 FPS since I have a 144hz monitor. I've been seeing some random drops in FPS to as low as 90, which isn't exactly low - but does cause some stuttering and frame skipping when in game.
Either way, I've got no idea what's causing it. I'm playing on an i5 4690k, GTX 1080, 16GB RAM and have league installed on an SSD, which as far as I'm aware, should be able to run league at 144 FPS fairly easily. This is the only game I'm seeing FPS drops with so I've pretty much crossed off that it's either drivers or hardware issues that might be a cause.
I'm interested to know if anyone else has similar problems, or if it's a common thing, or even just if anyone else has similar issues!
