Valve released the latest Beta for Proton 11 which brings with it an upgrade for FEX, the emulator to run x86 applications on ARM64 Linux devices.
FEX is part of the special sauce that together with Proton and Lepton will enable many x86 Windows games to run on the upcoming Steam Frame which uses SteamOS Linux as the operating system.
The proton-11.0-1-beta3 changelog on Valve's Proton GitHub page notes:
- Updated to FEX-2605.
The FEX changelogs are always quite detailed and heavy on the low-level stuff so the gist for FEX-2605 release brings: various performance improvements for 32-bit and 64-bit games, fixed a crash with controllers and lots of work towards proper support for the Snapdragon X2 Elite.
Valve's main Proton changelog states that Proton Experimental also has the Proton 11 Beta 3 changes.
If you missed other recent Steam Frame related news - Unreal Engine 5.8 adds experimental Steam Frame support and Qualcomm give the Steam Frame a dedicated page along with new Steamworks documentation for developers. GamingOnLinux also previously covered the different ways games will run on Valve's Steam Frame.
Hopefully the release announcement for the Frame isn't far off now!

In my wardrobe, I have both the PlayStationVR and the PlayStationVR 2. The original model had loads of support, but has such a low refresh rate and resolution that you can't play for more than fifteen minutes without severe headaches (which seems to get worse with age). I don't have that problem with the PlayStationVR2 - but there's virtually no support for it!
Hopefully the Steam Frame - which is a stupid name - will change all that.

Yeah the name is a bit odd but I don't think calling it the INDEX 2 would work either since the Index was very different to how it worked and people would certainly get the requirements mixed up. (like needing PC, tether and tracking stations)
Even tho the Frame is still technically needing a PC. It has been said it should be able to play Quest-3 tier games no problems standalone if you can install the APK.

Or do the two models run on different console generations?

Quoting: PhlebiacNah, PlayStationVR games are not compatible PlayStationVR 2... Which is a HUGE design flaw. And 99% of the developers for PlayStationVR haven't ported their content over to PlayStation VR2, either.Quoting: Cyba.CowboyIn my wardrobe, I have both the PlayStationVR and the PlayStationVR 2.

From a technical standpoint, PlayStationVR 2 is pretty much the best consumer-grade virtual reality headset money can buy at the moment - and even in the industry as a whole, it's among the best as I understand it - yet PlayStation have done nothing with it, the original PlayStationVR titles are not compatible with it, developers and PlayStation alike have shown very little interest in it.
I really don't understand the logic here at all.

Quoting: PhlebiacPlayStation Move actually ended up being really useful when used in combination with PlayStationVR (the latter was specifically designed to make use of it, presumably because there wasn't much interest in PlayStation Move as a stand-alone product)... I still have my PlayStation Move controllers around here.Quoting: Cyba.Cowboydevelopers and PlayStation alike have shown very little interest in it.I guess it's a question of catching the fad at the right time.

But you're absolutely right - timing is everything.
And I'm not yet convinced that the Steam Frame will get virtual reality to take off... But it might catch some of market share with its other uses, such as the ability to stream movies wirelessly from a giant "screen" pretty much anywhere there's an Internet connection. If it spurs interest in virtual reality again though, great - I'm the guy that still believes the Holo Deck is the future of entertainment.
