There's a system on Samsung phones that monitors temp and game activity. To be fully accurate, it slows the phone down so playing a game for 10 minutes doesn't overheat your phone. This can be disabled for full game performance. The issue is, if you do that, after a few minutes you'll overheat and slow down a ton. If you want as much game performance as you can, in the gaming menu, press the 3 dots in the top right, press game booster and set it to performance mode. The phone will do what it can to make games run as good as they can. In terms of overlooking. Technically you can. In the good guardians app, thermal guardian allows you to increase the thermal limit by 2c and disable some limiters. Your phone will get hotter but you'll get a little extra performance out of it.
