It was Qt5, which is pretty recent, so no fixed pipelines are
That's kind of what I was surprised about looking through Qt.
Quite a bit of it is still done on the CPU, things I wouldn't
have expected. Which is why I was wondering if there was any more
information on the topic.
IIRC GPUs are limited in what they can do in parallel, so if you
only need to do 1 things for a specific job the rest of the GPU
isn't really being fully utilized.
