Real shame it’s only 60Hz at 4k. There’s a gap for good 120Hz@4k streaming. Hoping the next Apple TV will do it. Edit - updated specs claim it can do this, but it’s limited to HDMI 2.0

(rewriting this comment because the spec sheet has seemingly been updated) Looks like it can do 4k 120hz, but since it's limited to HDMI 2.0 it will have to rely on 4:2:0 chroma subsampling to get there. Unfortunately the lack of HDMI 2.1 might be down to politics, the RDNA3 GPU they're using should support it in hardware, but the HDMI Forum has blocked AMD from releasing an open source HDMI 2.1 implementation. https…

It seems it supports DP 1.4 as well, so perhaps you could get an adapter if your display only supports HDMI 2.1

Now that they've ported Steam to Android with FEX + Proton [0] (what this is running), the question is will they release it for the rest of Android devices? There is a ton of Android gaming handhelds and people are already experimenting with things like Winlator [1] but having well supported way could be awesome.

OLED only burns in if the content is static for hours. If your head is that stable while using VR, I give you $5.

OLED is always burning in as a feature of it. It’s just much less noticeable when it’s: * cooled aggressively * constantly changing colors (more even wear) But it is still always losing durability in a steady way.

I used colorcontrol to enter the service menu of my LG C2 and disable all anti-burn-in features. No auto dimming, no auto picture level, no anti-logo, etc. The only one I kept is pixel shift because it's only noticeable if you're looking at the edge of the screen when it moves, it's a tiny movement. I skip the "pixel cleaning" prompt every time it wants me to wait. When I'm gaming in HDR, I use filters to increase the exposure to get the maximum brightness range of the panel. Been using it like that for ~8hrs/day for over 2 years now. Zero detectable hint of burn-in.

>2160 x 2160 LCD (per eye) Here's hoping it will be like the Deck and we get Frame OLED in a year or so.

Last time I read up on OLED in VR, it was said that pancake lenses dissipate too much light. Might be dated of course, and iirc there is now at least one OLED+pancake HMD on the market.

The whole "foveated streaming" sounds absolutely fascinating. If they can actually pull off doing it accurately in real time , that would be incredible. I can't even imagine the technical work behind the scenes to make it all work. I'd really like to know what the experience is like of using it, both for games and something like video.

There's an awesome shader on shadertoy that illustrates just how extreme the fovea focus is: https://www.shadertoy.com/view/4dsXzM Linus the shrill/yappy poodle and his channel are less than worthless IMO.

Imagine if we could hook this into game rendering as well. Have super high resolution models, textures, shadows, etc near where the player is looking, and use lower LoDs elsewhere.

It could really push the boundaries of detail and efficiency, if we could somehow do it real-time for something that complex. (Streaming video sounds a lot easier)

Foveated streaming! That's a great idea.

Foveated streaming is wild to me. Saccades are commonly as low as 20-30ms when reading text, so guaranteeing that latency over 2.4Ghz seems Sisyphean.

I wonder if they have an ML model doing partial upscaling until the eyetracking state is propagated and the full resolution image under the new fovea position is available. It also makes me wonder if there's some way to do neural compression of the peripheral vision optimized for a nice balance between peripheral vision and hints in the embedding to allow for nicer upscaling.

> Roughly equivalent resolution to Quest 3 and less than Vision Pro. This won't be suitable as a monitor replacement for general desktop use. But the price is hopefully low. Question, what is the criteria for deciding this to be the case? Could you not just move your face closer to the virtual screen to see finer details?

There's no precise criteria but the usual measure is ppd (pixels per degree) and it needs to be high enough such that detailed content (such as text) displayed at a reasonable size is clearly legible without eye strain.

> "Could you not just move your face closer to the virtual screen to see finer details?"

Sure, but then you have the problem of, say, using an IMAX screen as your computer monitor. The level of head motion required to consume screen content (i.e., a ton of large head movements) would make the device very uncomfortable quite quickly.

The Vision Pro has about ~35ppd and generally people seems to think it hits the bar for monitor replacement. Meta Quest 3 has ~25ppd and generally people seem to think it does not. The Steam Frame is specs-wise much closer to Quest 3 than Vision Pro.

There are some software things you can do to increase legibility of details like text, but ultimately you do need physical pixels.
