120gb download then forced to update another 60gb via launcher to be able to install DLC.

Game now wants to open GOG launcher when run and has shoehorned in a Project Red launcher resulting in ~5% worse performance.

The whole reason I bought through GOG was to not have launchers running in the background.

Go to your game install directory and launch the game directly from the main .exe.
[X]\Cyberpunk 2077\bin\x64\Cyberpunk2077.exe

That will bypass any of the useless game clients. I don't have GoG Galaxy installed, and I still haven't even seen this "Red Launcher" on my PC.

That just opened the Red Launcher for me, which incidentally wasn't uninstalled along with the rest of the game.

After a day of downloading only to end up with two launchers wanting to run in the background anyway, I'm done. I refunded it earlier.

Strange...The "Cyberpunk2077.exe" in the "bin" folder should be the offline executable. It's literally disconnected from any DRM, not sure why yours opens the launcher.

There's also "Launch Cyberpunk 2077" which is a different file that opens RED launcher.

Before updating via the GOG launcher in order to install the DLC it just opened the game, after updating it opened up at least the Red Launcher however I tried to launch it.
