it's the same on XBOX one S also.
Some textures seem heavily compressed, Others don't wich makes for a blocky experience.
Replay mode isn't that bad.
Also when it rains the game becomes unplayable. Like there is a massive memory leak somewhere. after a few laps the frames hit around 1-10 fps on the XBOX one s and then it will crash.
I wasn't expecting 4k crisp sharp visuals on my S, But I at least expected a playable game.
I wouldn't even mind downloading an extra 20GB for uncompressed textures.
