Cyberpunk 2077 day one patch has already been announced and it's no small release.
The day one patch is ranging in size from 25 to 30 GB with no official notes attached to it yet. Game developer, CD Projekt Red, will most likely include patch notes once the game is officially released on Thursday, Dec. 10.
Cyberpunk 2077 Day One Patch
Without official accompanying patch notes, it's tough to say exactly what is included in the massive patch. Speculation and trends based on traditional day one patches would point to stability and performance improvements.
Game reviewers have been playing the game before its official release and reporting any and all bugs and issues they find. With a massive open world game like Cyberpunk 2077, it's no surprise there are still some kinks to work out.
It's also believed that this patch is the main reason the game's release date was pushed back from Nov. 19 to Dec. 10. CD Projekt Red first announced Cyberpunk 2077 back in 2012 so it's no surprise the developers are taking their time to ensure they deliver a clean and smooth finished product. Anything less would greatly tarnish the amount of time and effort put into the game.
