Valve has announce that they've added a new rendering capability to their Steam VR environment which aims to improve image quality and frames per second in VR environments, while reducing processing load on both over and underpowered hardware. The auto resolution scaling feature they've introduced to Steam VR is nothing really new - it's been used in some games for a while now, and has recently begun attracting wide industry and game developer interest mainly on the back of the new, revised mid-gen upgrade consoles from Sony (the PS4 Pro) and Microsoft (Xbox One X).

The idea behind the auto resolution scaling is that developers (or users) can set a given frame rate target, and rendering resolution will be automatically adjusted so as to facilitate those FPS values to be achieved - wither by increasing rendering resolution (and thus image quality) in less work-intensive areas, or doing the reverse, and reducing rendering resolution in performance-hog stretches of games or experiences.
