My spouse and I both want to play 2077 and neither of us is willing to leave Windows 7.

I noticed the Steam page now shows Windows 7 is supported. Is this true? If so, will 2077 run the same on Win7 and Win10, or will there be differences?

Also, will 2077 support Steam Family Sharing in the Steam version?

Will there be any restrictions on the GOG version?

Will buying the Steam version grant you free access to the GOG version?

Thanks.

Windows 7 is officially supported and part of the minium system requirements. No officially mentioned differences.

Cyberpunk 2077 will be DRM free even with the Steam version, just like The Witcher 3, so theoretically there is no need for Steam Family Sharing, as you could just share the whole game data and play offline. According to the Steam Store page The Witcher 3 is not in the Family Share program, so i doubt Cyberpunk will be.

No restrictions.

No, not at the time of release. Maybe later just like they did with The Witcher.
