A paid software called Lossless Scaling has been tested on Steam Deck OLED. At the core, the software can scale resolutions and add frame generation. These two can make games feel a lot smoother on the gaming handheld.https://www.notebookcheck.net/Lossless-Scaling-on-Steam-Deck-OLED-runs-games-at-up-to-2x-FPS.879563.0.html
As someone who owns a number of devices that have weak (IE: GTX) GPU's this was inexpensive enough so I bought it.
Much like anything Steam, I was able to install in on multiple devices. :)
However it ought to be said that outside of setting your game to a lower resolution and then using this program to 'lossless scale' to your actual screen resolution the 'frame generation' is simply kidding us - frames not rendered by the GPU don't show differences in action in the game.
IMHO: if we keep this sort of technology in context it can help to speed up games on weaker hardware.
The only deck news I'm possibly interested in hearing is in when the steam deck 2 is releasing. Although I'm not sure I even care about this anymore seeing as it seems Playstation and Xbox are getting serious in releasing a handheld by 2026. Whatever deal that valve could possibly bargain for when it comes to a custom silicon APU for an upcoming handheld, both Sony & Microsoft would be be paying AMD way more so they would end up getting the most superior chip by far. And if they release with a locked down OS, some hacker will just jailbreak it and get steam running on it anyway.
