But for the sake of interest, my last phone was weaker and worked better in this game (there were 6 RAM and 8 cores), why is a more powerful phone lagging without changes in the game settings?No offense, I'm just curious.
Some programs aren't optimized to run on Mediatek SoCs, even if they're faster on paper than older snapdragon ones. That might have something to do with it? Also it might be worth checking whether your new phone has a significantly higher res display than the old one.
