By no means is this a solved problem.

NV_path_rendering is an implementation of "stencil then cover" method with a lot of CPU preprocessing.

It's also only available on OpenGL, not on any other graphics API.

The STC method scales very badly with increasing resolutions as it is using a lot of fill rate and memory bandwidth.

It's mostly using GPU fixed function units (rasterizer and stencil test), leaving the "shader cores" practically idle.

There's a lot of room for improvement to get more performance and better GPU utilization.
