Watch Dogs: Legion is out today on current-gen systems, and Ubisoft is addressing some issues in day one update. Most notably, performance is being improved on PC (for those with RTX GPUs specifically) and PS4, and some various bugs and crashing issues have been cleaned up on all platforms. You can check out the notes for the hotfix, below.

This update is available now on Xbox One and PS4, and will hit PC on October 30. It should be mentioned, that it seems this update doesn’t seem to address a reported game-breaking bug in the Xbox One X version of the game, which caused the game to crash during a specific point in the “404” mission. Ubisoft has told the folks at Eurogamer that a hotfix for that issue is likely coming on October 30.
