> I wonder what the math would look like to properly render 3D scenes onto a curved display. Could it be accelerated as well as the regular matrix operations used for perspective projection onto planar screens?

The math is pretty simple to account for a curved viewport, even though I don't think any apps actually care about that. Most displays aren't curved enough to make it a meaningful difference.

We don't have fixed function pipelines anymore either so that could definitely be handled by hardware.
