Agree on the rendering speed, I was working on some experimental visualizers in LOVE which drew lots of individual pixels. I ended up having to rewrite a bunch of it in shader language to get decent FPS. This might be true with other frameworks too though, I understand graphics are not an easy thing to just automagically optimize.
