Hi, I would love some help with this:
From when I started playing LoL on this computer until... yesterday, I've never dropped below 50-60 FPS, except when Graves Smokescreened me or when an enemy Nocturne ulted.
Starting yesterday (before the transition to the winter map), all of my games have started at 50+ FPS. Over time, the FPS fell. By the time I was 10 minutes into a game, my FPS fell to around 30 or so. By the 15 minute mark, it would be below 20.
My FPS in late game tends to have a consistent maximum of 15 or so, often dropping below 5 in teamfights.
I have not changed any video settings from the default ones. I defrag on a regular basis. I have checked for viruses (ESET Smart Security). I play LoL without background applications.
My GPU is an Nvidia GeForce GTX 485m.
Anyone have any ideas as to what may be causing this?
