Meta today introduced a new developer feature called Super Resolution that’s designed to improve the look of VR apps and games on Quest. The company says the new feature offers better quality upscaling at similar costs as previous techniques.
Meta today announced the new Super Resolution feature for developers on the company’s XR developer blog. Available for apps built on the Quest V55 update and later, Super Resolution is a new upscaling method for applications that aren’t already rendering at the screen’s display resolution (as many do in order to meet performance requirements).
“Super Resolution is a VR-optimized edge-aware scaling and sharpening algorithm built upon Snapdragon Game Super Resolution with Meta Quest-specific performance optimizations developed in collaboration with the Qualcomm Graphics Team,” the company says.
Meta further explains that, by default, apps are scaled up to the headset’s display resolution with bilinear scaling, which is fast but often introduces blurring in the process. Super Resolution is presented as an alternative that can produce better upscaling results with low performance costs.
“Super Resolution is a single-pass spatial upscaling and sharpening technique optimized to run on Meta Quest devices. It uses edge- and contrast-aware filtering to preserve and enhance details in the foveal region while minimizing halos and artifacts.”
Unlike the recent improvements to CPU and GPU power on Quest headsets, Super Resolution isn’t an automatic benefit to all applications; developers will need to opt-in to the feature, and even then, Meta warns that benefits from the feature will need to be assessed on an app-by-app basis.
“The exact GPU cost of Super Resolution is content-dependent, as Super Resolution devotes more computation to regions of the image with fine detail. The cost of enabling Super Resolution over the default bilinear filtering is lower for content containing primarily regions of solid colors or smooth gradients when compared to content with highly detailed images or objects,” the company explains.
Developers can implement Super Resolution into Quest apps on V55+ immediately, and those using Quest Link (AKA Oculus Link) for PC VR content can also enable the sharpening feature by using the Oculus Debug Tool and setting the Link Sharpening option to Quality.
