Indeed. It is rare to encounter a webgl/gpu visualization that doesn't rev up the fans at 100% while sitting idle, let alone to have this low latency handling input. Virtually all web demos I have seen run terribly because literally 0 attention is paid to actual rendering. The other day somebody submitted one here and admitted they didn't know backface culling was a thing. They also almost universally have no sort of frame pacing.
