While playing MC bedrock on my xbox one s it was running perfect at solid 60fps the whole time, 

Now on my xbox series X its running at maximum 45fps in a brand new world, i even tried putting down the settings but it didn't work and still kept lagging the entire time while playing which is quite annoying when it can run triple A titles in 4K 60FPS HDR but it can't play minecraft at 1080p with a higher framerate than 45...
