I have recently bought the 8th gen helios 300(PH315-51). I am getting random fps drops in games.
I get around 120 fps in fortnite and after 5 mins of playing it drops to around 10-20 fps for like 5-10 secs and then goes back up to 120. This keeps on repeating.
I have tried turning of the Geforce Experience screen overlay, and i have also updated the Bios, Nvidia drivers. My temps while playing : 70-90 CPU and 60-80 GPU
