With the myriad of lists and confirmations, Valve has released its own confirmation tool for those who are going to be getting the Steam Deck either this coming week (Feb 25th) or in the coming months. 

The tool isn't particularly complex, as it links in with your Steam Library through a sign in and then will show you all the games either playable, verified or not working. 

You don't even need to have a PC with Steam on it, as you can see in the browser version of Steam to get a gist of what isn't and is eligible. 

From what we can see, a well-stocked Steam account like our darling author here has around 630 games not yet tested in any capacity. It is assumed that Valve will be going off of the Proton database, the community-curated list of games that have been tested using Valve's intermediary compatibility layer to convert games developed for Windows to Linux, which the Steam Deck's SteamOS is based on. 

As of right now, Proton DB has tested over 18, 000 Steam games, with a total of 12,383 with at least one positive report of working, which might not sound like a great backing, but there are hundreds of smaller titles that won't be a priority to get seen to or tested by Valve in the meantime. 

So far, Proton seems to be providing a good level of performance on Linux and is opening the path for developers to have a new source of audiences, as well as opening a new path for a lot of gamers to move away from the dominating force that is Windows. 

You can check our guides for recommendations of games to try on the Steam Deck, or see the best approximation for those of you who can't wait to get the console.
