so recently (at the start of january) i got a brand new 2023 acer nitro 5 with 12th gen i7 and rtx 4060. performance up until last wednesday had been very good, mostly using it to play microsoft flight simulator with a solid 70-100 fps. However, for some reason on wednesday, I suddenly was only getting around 20 fps under similar conditions in microsoft flight sim. Initially, I thought it was just flight sim issue, so I tried removing some mods, deleting and reinstalling, changing graphics settings to default etc. None of these methods did anything except graphics settings which only got me to 40 or so fps. I thought I would just play some other games, and realized that I was getting considerably less frames in those as well. I'm not sure what is wrong and very confused as have only had laptop for about 2 months. If anyone could help it would be much appreciated.
