This is really great to hear, but where is this explicitly stated? You know, this is something that bothers me every time someone recommends adding non-steam games to Steam and simply force them to run with Proton (on a sidenote, up to this day I have NOT managed to get Steam to run the GOG version of Cyberpunk using Proton, but this is probably just my botched system).

Basically, whatever you can run via Proton should run. despite being clearly categorized in the latter area.Frogthroat: Cyberpunk 2077 should work directly from your Steam library but they also advertise that you can install 3rd party games - so it should be possible to get even the GOG version working directly. With the widespread diffusion of the device, however, more and more teams and publishers seem interested in making their products compatible on Steam Deck, demonstrating how the Valve laptop is increasingly a credible alternative to consoles and the standard PC. On the other hand, the story is different for those that came out before the launch of the device, for which the verification process is carried out more at the discretion of the developers who may be less interested in carrying it out. The famous RPG by CD Projekt RED therefore joins the ever-growing list of games that have been verified for Steam Deck, having also perhaps taken longer than expected, considering how many recent titles obtain certification before launch or shortly after.

Cyberpunk 2077 gets the coveted check that makes it Verified For Steam Decksthat is totally compatible with the Valve laptop, having passed all the tests necessary to evaluate its correct functioning.
