How big a deal is this eye tracking that then only shows higher resolution stuff where you’re looking? Is it legit and works well, or is it a gimmick VR uses to say its’ better than it is?
Does every game need to support it in a way, or would this be done on an OS level? Because I don’t know, from my experience, the game tells how detailed anything has to be rendered in a frame.
The games that will play natively on the steam frame will have to support it on a game level, but for streaming it’s handled at the os level through “Foveated Streaming”. So the PC isn’t getting an fps boost from it but it does allow the latency to be very low through streaming.
I’m not sure that the eye tracking data will be passed through for foveated rendering from the PC side though I can’t imagine why it wouldn’t. In that case you get both render and streaming which would be incredible
I wonder if valve can multi purpose the SDK for streaming and give it to game devs and say use this sdk to determine where to adjust how things being rendered, and make it eventually a no brainer easy to use add on.
They showed a special build of Alyx only rendering where the eyes are looking and supposedly even that works well. I bet they’re working on a version of Alyx that can run natively on the Frame but it wasn’t fully ready for the announcement.
Valve has only made mention of streaming bandwidth, nothing about the game being rendered (like how PSVR2 does it). As it stands it won’t do anything for the GPU performance.
Maybe there’s some sort of API games will be able to hook into, I seriously hope so.

Foviated rendering is a massive thing, usually only done in the expensive stuff.
It gives you a pretty big FPS boost because the device doesn’t have to render stuff the human eye can’t see anyway

Thanks for your insight :)
This is foviated streaming. The PC still renders everything at full, but the streaming compression is optimized for where you’re looking
Does that mean there’s no forviated rendering in standalone mode?
I imagine there will be for some games, but it relies on the game developer implementing it. Whereas foviated streaming works for all games.

And maybe a HL3 that works both in VR and flat.
it’s a huge thing
legit works well… but also not a magic wand. It doesn’t transform a low-end rig in a powerful machine.

AFAICT for the Frame it’s only foveated streaming, not foveated rendering.
They showed a special build of Alyx rendering only what the player is looking at. I guess they didn’t focus on foveated rendering because it’s
Foveated streaming will work with all games.
Apple vision pros do it and it is pretty great
