Not using the GPU for simple stuff is something I've learnt when I was looking to add vector graphics to my scientific visualization library, and it turned out that just using Blend2D to render the vectors on CPU, then upload to the GPU and composite with the GPU rendered stuff was more efficient (quicker and used less energy) than trying to coax the GPU into doing it.

@datenwolf@chaos.social @navi@social.vlhl.dev @neal@social.gompa.me @dalias@hachyderm.io @miah@hachyderm.io well vector graphics on GPU (fonts in particular) are its own can of worms; that stuff hasn’t been done efficiently on GPUs until recently (with newer graphics APIs). for older GPUs and APIs i definitely agree with you 100%, but things have been changing.
