Yet another update for Molecules is now live on the App Store, this time version 2.02. The focus of this update is performance, and the new version greatly improves the speed of the new rendering engine. The 3-D models are now rendered at 3-6 times the speed that they were in the previous version, which should make previously choppy framerates on the iPad 1 much smoother. If you're interested in how this significant optimization was achieved, check out my question about it on Stack Overflow. Thanks go out to Tommy and Pivot for pointing me in the right direction on this.
