Patch 1.21 was not a cure-all. Some long-standing issues persisted: occasional physics oddities in extreme scenarios, and the game’s age still showed in performance variance across hardware. But the tone had shifted. Where frustration had been louder than praise before the update, players now traded tips for scenic photo routes and curated car lists. The update didn’t add new mountains to climb; it cleared pebbles from the path.
