It's there now. 54.21GB

Just started the update on GOG, 54GB.

I had Galaxy open, waiting for the update to drop. Nothing. So, I did a check for update and it started. You may need to do the same thing if the update doesn't appear.

54GB downloading...

I knew the update would be big but was hoping it wouldn't require essentially re-downloading the entire game.

We're redownloading the whole game. The 1.63 CP2077 had like 63GB, so the 2.0 is lighter :)

I just tried download and freshly installing the 2.0 version of the game on top of my existing, heavily modded 1.6.
Downloaded all the game files, and went for it. I was missing -15.bin (forgot to download it), and yet the game installed successfully.

Got an error regarding RedMod on first startup, code 102. Which was odd, as I have never installed RedMod at all.

Anywho, I got to the main menu and the game says "patch 2.0". But before that, I got a popup displaying a Phantom Liberty wallpaper, and a blank / no text download link window. This window was not possible to close.

...Except it now has closed itself, and has been replaced with a, and I quote:
"Generip popup"
Generic Message popup. Lorem ipsum sit amen dolor" (which is the latin equivalent of "insert text here").

Game loaded in just fine...except every character VO was muted. Possibly due to my recently installed Japanese VO mod. Retesting with default English audio now.
EDIT: Default English VO worked fine.

Weapon mods are broken. There are "LocKey" errors all over the place. Character window is blank (got 104 perk points available). Hacking doesn't work at all (can't actually exdcute any hacks). Mouse cursor is missing in the text messages (also, more LocKey errors).

...And sadly all game mods are broken, though that at least was expected.

I'll switch back to copy of 1.6 now, and wait for the 2.1 patch.

No FSR3.0 I noticed. Odd.

How is that odd. Fsr 3 is still not out.
