Valve's SteamOS 3.7.3 Preview improves support for Asus and Lenovo handhelds

By Liam Dawe - 16 Apr 2025 at 8:22 am UTC

After Valve announced in January that a public beta of Steam Deck's SteamOS is coming for more handhelds, the initial SteamOS 3.7 Preview added the start of it and now the latest SteamOS 3.7.3 Preview brings more improvements for other handhelds.

SteamOS 3.7.3 Preview "Variable Release Rate" arrived April 16 with these changes:

Added support for frame limiting with VRR displays (internal and external).

Fixed a crash when no displays are connected.

Added support for the power button on Asus and Lenovo handhelds.

Improved input support for Asus and Lenovo handhelds.

This is available for Steam Deck in the Preview channel (Settings > System > System Update Channel).

Many people have been trying it on other handhelds using the SteamOS recovery image download, but it's not recommended yet since there's still a lot of work to be done but clearly Valve are making some nice steps towards that proper public release.

Exciting times ahead for the Linux gaming community. The public SteamOS 3 release should be quite a big boost. And hopefully we'll see more hardware vendors support it officially with you being able to eventually buy more handhelds with SteamOS 3 shipping on them like the Legion Go S.

Those names for the updates are just great :)

Regarding certain firmware updates (and maybe even games), I guess a dual boot install is what's preferrable. My son loves to play some games that are not available on Linux, so I decided to keep Windows on the Ally (and it was quite the hazzle to shrink the partition). Though I'm very happy about using a SteamOS like install on the Ally, there are some issue. E.g. the UI becomes slow over time or after stand by. Sometimes it also feels like IO is getting slower.

Yet it's much better to nagivate than Windows and the vendor's own solution like Armory Crate or Legion Space.

I'm wondering if Valve has some special optimisations, or if using Bazzite and Steam OS will have identical performance.

And I hope they also take into consideration to support egpus, especially the XG Mobile one (as I got one). Though they do already work, having an easy way to enable/disable would be appreciated. And then it would be awesome if VR would work too. Currently I'm not able to get VR up and running on the Ally+egpu and Bazzite.

I have been using SteamOS on my homemade Steam Machine, and it's looking good. The power limit slider correctly goes to 165 W, can switch between 120 MHz and 60 MHz as supported by my TV. So it's not just for handhelds.
