Ya this is effectively a non issue. https://www.roadtovr.com/nvidia-perceptually-based-foveated-rendering-research/ https://www.roadtovr.com/nvidia-perceptually-based-foveated-... The primary issues in this space is latency not raw power.

> Ya this is effectively a non issue. Yeah. If the new panel is presented as 3x or 4x 1080p (two foveal insets and one or two backgrounds), and tolerates 30 fps, I could run it off the old integrated graphics I'm typing at now. > The primary issues in this space is latency For immersive VR, yes. But as one moves away from gaming, and immersive, and VR, design constraints relax a lot. There's so much ambient confusion about the shape of the broader design space, and misattribution of constraints. I usually use my WMR (and Vive before that) on an old laptop with Intel integrated graphics. A duct-taped-on 30 fps camera-passthrough AR serves for balance, permitting <30 fps rendering for a software development 3D "desktop". Latency, and its variance, is just not a challenge here. I can even do subpixel rendering on the WMR. Lens focus is so bad, subpixels are only worth bothering with for like (0.5 kP)^2/eye (of the ~1 kP square/eye usable area, of the 1.4 kP square/eye panel). There's no point in even rendering full native resolution over much of the visual field. And not caring about immersion, there's no need for barrel and chromatic correction, nor for blending away seams between resolutions. Such a vast amount of effort is spent on dealing with "horrible immersion-breaking visual artifacts", which for some parts of design space, are like "meh, sooo don't care". Remember the skeuomorphic user interface fad of a decade ago? A calender app should look like a leather-bound calendar book? And... remember all the claims that calendar apps wouldn't be viable for years, because of the GPU demands of faithfully rendering light reflection off the leather. Yeah, me neither. That would have been silly. Just like expecting a 3D/HMD professional "desktop" environment to prioritize immersion.
