Foveated Streaming seems to be buried on the page, this feels like a true game changer, especially for PCVR. Coupled with eye tracking it unlocks about 2-3x more compute for rendering. Now sparkle DLSS-like upscaling and you can render 144hz native resolution PCVR games without buying a 5090. Truly exciting stuff.
I still remember Michael Abrash's talk from 2016 where he talks about Foveated Rendering + Eye tracking as one of the key pillars of next-gen headsets https://youtu.be/o7OpS7pZ5ok?t=5438 https://youtu.be/o7OpS7pZ5ok?t=5438. Interestingly, his prediction was that it would be widespread as of about 5 years ago. Is next-gen finally here after 10 years?
- sunaurus 18d agoNot quite: foveated streaming only affects the bitrate of the stream. For improving rendering performance, there is a similar technique called foveated rendering. It's still somewhat unclear how well that works while streaming, though. In theory, it should work, but no reviewers seem to have covered it for some reason.
- teravor 18d agoyou would probably need special engine optimizations to really make use of it, and VR hasn't been exactly an attractive option for AAA games.
- paulryanrogers 18d agoDLSS adds lag, as does wireless, that 144hz may not help as much in those cases. For me it's the lag that gives me headaches.
- RomanKornev 18d agoDoesn't it render at half or even quarter resolution before upscaling, so wouldn't it be less e2e latency overall?
- MayeulC 18d agoI do wonder if they use local upscaling after foveated rendering/streaming. The screenshot I've seen look a bit aliased in the periphery, which I hope isn't too distracting.
- RomanKornev 18d agoSnapdragon 8 Gen 3 does have a dedicated Hexagon NPU, so supposedly it can be done, but quality might not be great
