That is the problem. It's not easy to implement as a complete solution. On PSVR/Quest it's as easy as just changing a driver setting. Nvidia need to make it something where developers don't have to implement it and it can just work by turning foveated rendering on or off like the usual settings they have in the control panel. VRSS does not even work this way right now since it only works with whitelisted apps.
