it's highly dependent on what's actually drawn. i regressed it by accident and didnt notice a huge difference until i randomly opened the stress test (which is also densely packed so probably a worst case for AA)[1]. it went up by a factor of 2-4. cant remember exactly.
- drawing at exact aligned pixel boundaries to avoid or minimize antialiasing
this makes uPlot charts a bit rougher looking, but the perf impact is quite large.
