Valve has released a huge Stable update for SteamOS with version 3.2 now available for updating on your Steam Deck. Here's what's new. A lot of this isn't exactly new-news, since it's pushing out most of the changes from the Beta you could opt into at any point. 

SteamOS 3.2 includes:

  • Added an OS-controlled fan curve to improve the experience in low usage scenarios, and adjusting how the fan responds to different scenarios and temperatures.
    • The old version of the fan curve is still available, and can be turned on in Settings > System
  • Added support for changing the in-game screen refresh rate. The refresh rate will automatically be adjusted to the desired option when going in and out of game.
    • There is a new slider in the Quick Access Menu > Performance tab that allows you to choose a screen refresh rate between 40-60Hz
    • The framerate limit slider values will update accordingly, and will include 1:1, 1:2, 1:4, or uncapped framerate options.
  • Fixed an issue with typing the € key using the Steam keyboard
  • Performance HUD now shows a more accurate reading of VRAM used (previously would cap out at 1G used)
  • Added more internal screen resolution options for games to choose from
  • Fixed gain staging, resulting in higher max speaker volume, and removes white noise coming through 3.5mm jack with some headphones.
  • Fixed PipeWire and Steam failing to elevate their thread priorities
  • Fixed the language dropdown in the Warframe launcher
  • microSD card formatting process now performs a quick format

Additionally though, there's also the Steam Deck Client update that came along with it. This includes now full and proper support for Remote Play Together. So you will be able to host and join games using that feature. As a reminder, it allows one person who owns a game to let others join, who get it streamed from the host.

On top of that there's a notification if the Steam Deck SSD hits below 2GB space, you can name controller layout commands, you can connect to hidden wireless networks, there's icons for gamepad and mouse commands shown on in-game virtual menus and even the ability to close a window if the game / app you're running has more than one visible (an update to the window-switcher).

The fan changes really are the biggest thing here though. One of the fans the Steam Deck ships with is far louder than the other, with a high-pitch that comes with it. This new fan curve is massively quieter and just makes the experience so much nicer overall.

Second being the refresh rate switching, not to be confused with dynamic refresh rate, as this allows you to switch to a specific-set refresh rate like 40Hz. As Valve explained on that part:

So 30hz = 33.33 ms/frame, and 60hz = 16.66ms/frame. Meanwhile, 40hz is 25 ms/frame. So while it might seem a bit counter intuitive, 40fps is exactly half-way between 30 fps and 60 fps in terms of update speed, and as such looks and feels far more responsive than 30fps. Generally speaking you always want a very stable frame pacing. So having a rock solid 40hz is better than oscillating between 42 and 48 hz, especially if your screen refresh is 60hz. This is because you're only actually getting a new frame each 1/60th of a second, so every time you miss, you get a double frame, leading to judder.

So a rock solid 40fps in game, with a 40hz updating screen, means every frame is a new frame and as a result it can feel smoother than an inconsistent framerate with a higher screen refresh. In addition, locking framerate lower puts less demand on the system and thus saves battery. While 40hz will use more battery than 30hz, it will use less than a game capped at a higher refresh, while still giving a subjectively far higher quality of an experience comparitively.

So when are we going to find a Deck verified multiplayer game we can do co-op in? Something like Left4dead!

There are actually quite a few co-op games listed as at least playable already, like Back 4 Blood, Deep Rock Galactic, 7 Days to Die, Satisfactory. Payday 2 for example is even marked as verified. I guess since Warframe is explicitly mentioned in the SteamOS 3.2 release notes it is supposed to work as well (no mentions on the store page yet). Note I didn't actually test any of them myself on the Deck yet, however except for Back 4 Blood I played all of them for quite some hours under Linux on the Desktop where they all worked great for me.

Yeah, I was suggesting that we have a 'Deck-together' session and play some games :)

Weird on the video that the Watts used don't decrease and even increase when lowering refresh rate for the monitor and fps

Valve adhering to the ol' "if at first you don't succeed..." mantra I see.

Here's hoping this week's update goes better than last week's updates and fixes. 🤞

Quotebetter fan curves

Does that qualify as "fan service" ?

So she's... whining about it? ;)

But to be serious: Such sounds can be very annoying.
