Other cars seem to teleport (not lag, just very unrealistic physics feel - what does not occur in single player) and their wheels instantly jump from full left to full right, even when they’re being driven smoothly. Which negatively impacts the gameplay experience, especially in convoys. These issues don’t occur in other games, and this is one of the reasons why multiplayer clips from Forza Drift don’t gain as much attention on social media compared to games like CarX. The most popular clips are from single player mode, because it doesn’t give an unpleasant lag feel.
PS: I mean, the physics in Forza are good and balanced, much better than in CarX, for example. It’s just the multiplayer animations that are bad, especially the wheels.
