performance: store in memory

This cycle of caching things on disk is probably pretty terrible for performance. 32GB of RAM has become fairly common-place, and I imagine anyone using this software is going to have at least that much. Despite that, memory usage remains low.

I recommend keeping your various buffers stored in main memory and GPU memory as much as possible instead of serializing them to disk. The cost of constantly serializing and parsing JPGs aside, constantly walking back and forth between disk and RAM must be enormously expensive.
