Will GeForce Now be able to run the full release version on August 3rd, or will it take some time for that to happen?
I just found this on GeForce Now Twitter Account
https://twitter.com/NVIDIAGFN/status/1686498608055472128?s=20Q: Will the Baldur's Gate 3 launch on the same day/time as Steam?
A: Unfortunately we don't have news to share on this right now. If and when we do have news, we'll share on our channels.
The tweet is from January though.
As an aside, since Swen recommended to delete EA save and mods, and have a clean install of the game. I wonder how this is going to work with people who start on GeForce Now. I am planning my first playthrough there, since I am still waiting for the Mac release date.
