I have a iPad Pro 12.9 3rd gen (Originally released in the end of 2018) and it runs Minecraft bedrock edition with a lot of frame drops and overall bad performance. I used to have a iPad Pro from 2017 that ran Minecraft super smooth and I would think the more powerful newer one would run it just as well or better. I'm guessing the game was optimized for the 2017 iPad Pro and hasn't been for the newer 2018 iPad Pro. I have messed with the settings and no matter what I do the game still lags. Thanks!
