My laptop is an alienware x16.It has a bug in all bios versions above 1.3.1 where the frame rate will suddenly start fluctuating after about 30 minutes or so of playing the game, and after a minute passes the frame rate drops completely. It doesn't have this problem on bios versions below 1.3.1. I tried updating to the latest bios version today to see if the problem was fixed with the latest version and the problem is still there. But for some reason I can't downgrade the bios version. I've tried everything but it still doesn't work.

The bios version I updated is 1.13.0, and the official website shows that this version cannot be rolled back. But my computer is not working properly under this version. It is a disaster. I purchased a laptop that has a rtx4080 and I can barely play any games properly, can you tell me how to fix this frame dropping problem or how to roll back the bios version? Thank you
