Hi, Im am an owner of Nitro laptop AN515-57. I own it for close to 9 months now and I was very satisfied with it until today. Good performance in all games I tried and 0 problems. When I started a game today, for some reason, from average 80-100, my frames dropped to 35 and later to 20. I tried multiple games and it seemes its not game-sided as I have roughly 20 fps in all of them. Before this, when I tried launching a game not plugged in, I had the same amount, 20 fps, but after I plugged it in, it jumped to 100. Now plugged and unplugged fps are the same. Charger is charging the battery. I tried focusing main gpu instead of the integrated one in NVIDIA cp. Didnt do anything. I did reset the laptop to factory settings with personal files remaining intact. Didnt work. I toyed with Nitro Sense power plans. Didnt work. Ive seen a few people having this problem, didnt see any solution. Between laptop working normally and performance drop there were no harware or software changes(except unplugging a mouse and charger). Thank you for your time.
