Interesting. To be fair it's not something I've experimented with personally - I'm just extrapolating based on pure CPU clock speeds.

I have definitely encountered the issue that it's hard to draw pixels using many modern graphics API's, but I would have thought there was a way to make it fast.

I guess it depends on what you're drawing and what the primitives are too. Interesting topic, and another reason making a DAW must be a fun project!
