The game is set to DX12 mode by default which always has shader generation stuttering in UE4. This can be changed with the command line -dx11 which will start the game in DX11 mode.
Note the Game pass version can't be changed to DX11 and will always run in DX12 mode this was the same in other UE4 game pass titles like the Ascent dunno why.
