IMHO, this is more an issue of dev's preferring to release updates to Steam rather than DRM-free distributors, and not an issue with Nvidia. Nvidia works with the dev's not the distributors, and their drivers are tuned to recognize only the latest version of a game, and that info comes from the dev's.
Belsirk: Are we sure this is the way Nvidia operates with the GeForce Experience ? Because always that I searched, was referenced to things like this: "
GeForce Experience uses the power of the NVIDIA cloud data center to provide optimal settings tailored to your PC". Honestly, seems more a manual work that will be done only for those game with certain status (and probably give extra money to them) than a direct dialogue with devs (Except by the part of money). I could be totally wrong as truly never had too much interest on this thing.
If were something with open dialogue, more games from Steam would have support in the GeForce Experience.
P.S.: That video is so old and over-used. LOL
Belsirk: Oh yes, but is a good reflex of what was Nvidia in the past, and how the market changed since then. And that was the point of my comment..
Yes, in one of the trouble shooting things I had read, it stated that the most likely reason that a supported game is not recognized my GFE is because it's not been updated to the latest version.
There are only a few dozen people that Nvidia has tweaking game settings, and it's well known that they make mistakes, e.g., Borderlands The Presequel has the wrong profile assigned to it for 3DVision. If a dev want's Nvidia GeForce to ID their game they have to contact them about it, ensure that their game meets certain criteria, i.e., not a sex game, compatible with a wide variety of GFX cards, and then provide Nvidia with a detailed list of how their game works graphically. As you might imagine, some dev's, especially Indie's, simply don't care to do so much extra work.
Interestingly enough, even some games that say, "Gaming Evolved - AMD" have been ID'd by GeForce Experience, meaning that the dev's went through all of that to do so.
