the game is not well-optimised for the original xbox one - i’m getting frame slowdowns when moving the camera around the car and panning it around in the cockpit in “home vista” mode = forza vista outside your house. p.s: camera’s very low, can’t peek inside the engine - weird.
also, there is a lot of noticeable texture pop in while driving - i’m just a few metres away from objects and i can see detail popping in and textures loading. the same goes for the map - textures load late when you bring it up.
the frame slowdowns also occur during racing, but not that often during free roam.
i haven’t noticed texture pop in or frame slowdowns in any of the other horizon games. i’ve been on fat xbox one since day one.
