Comment on Steam Frame Teardown: We’re Fans. Except of the Fan - iFixit

  How doed that even work? You can stream games from a Raspberry Pi. That’s why there’s an entire industry dedicated to exactly that.

    The point they are getting at is that in order to stream games to a VR headset, that headset needs to have a certain amount of compute power in order to interpret the stream while also handling tracking, connecting to controllers, etc. That amount of compute power is also capable of running games in standalone, so they may as well support that option as well.

      But that isn’t true at all, and I’ve still seen no one from valve actually claim it is true.

      That makes no sense. It requires more compute to run a whole-ass game along with tracking controllers than it does just tracking controllers.

        Streaming to a VR headset involves the headset computing more than just controller tracking. It needs to interpret the incoming stream and all sorts of other various things that need to be computed. A VR headset that has a processor that is powerful enough to stream heavy games is also powerful enough to play light games in standalone.

    There’s a fair bit of difference between streaming pre-recorded large frame video versus low latency live streaming with small frames and a bit less size efficient but more CPU efficient encoding, etc…

    And because of how SoC chips are binned (what components are offered together, economy of scale, etc), once you pick a SoC with a GPU with enough power to accelerate this decoding, you also have enough power total to do other stuff like on-device gaming simply because if you ask for a cheaper CPU it will cost you more for them to make a custom assembly (unless you ask for a large enough volume of custom chips).

    And don’t forget foveated rendering. Most of the magic making it capable of gaming with high quality comes from that. They didn’t put the highest tier chip in, they reduced the work it has to do instead

    VR streaming is a lot more demanding. You need ultra low latency decoding of much higher resolution and frame rate than 4k60.

    Where does the Raspberry Pi fit inside of that headset?

      Why would you think this headset uses a Raspberry Pi?

  Where do they say this? I don’t know why that much ram and processing and storage would be required for just the streaming and fov stuff.

    I’ve heard it in a few places, one that comes to mind being an interview with some engineers that PC Gamer did. The RAM was originally half (on par with the Quest 3) but once they realized how much the potential library would expand, they bumped the RAM to 16GB.

    This decision was made pre RAM crisis, of course.

      But that would have been in response to non streaming, where the headset handles everything. I’m talking about non streaming.

      Several people around here keep claiming valve said the hardware in it was pretty much the same hardware needed for a streaming only design, but no one has actually been able to provide a source of them saying it, and it sounds like BS in a rumor mill at this point. Especially because it doesn’t make any sense.
