Yeah, not too surprised they are expensive for performance, but the memory footprint would be nicer! the vertex texture thin always ends up with giant, usually unstreamable textures. Hurts my feelings :)
They aren't that bad if you disable collision updates on them - for a lot of our cases we don't need collision or we find a workaround.
