Packaged Game lagging after switching engine from 4.27 to 5.1

I have recently upgraded from UE 4.27 to 5.1
When I build the game using 4.27 it was running on my android devices at 60fps with Game time of 3 ms in stat unit. But after I upgraded engine to 5.1, without making any change in the game, I build it again, but now it runs at barely 20-25 fps with Game time of 30-40 ms in stat game. Can anyone help me why its happening, I am very confused.

Hi Ashutosh,

I think what you’re seeing is UE5 defaulting to high scalability settings when packaged.

This is the solution I found for Windows development, my first thought of one way to test this idea/fix on Android would be to use the ‘execute console command’ node to force lower settings.
