tyFlow has upresing abilities....specifically the "Particle Force" operator used on a reference flow. Have your reference flow a lower res, then set the "Particle Force" radius to roughly 75% of the reference flow's radius with about 50% falloff, and your higher-res grains should follow the linear/angular velocities within their falloff radii nicely.
As for RAM usage....maybe if you post a screencap of your flow I can see if anything incorrect stands out.....but tyFlow does try and keep RAM minimal. Some extra bookkeeping is required for bindings that can increase RAM if you have millions of particles. Also if you're trying to cache huge amounts of particles over a large time frame....the memory required to store the cached data per frame can get eaten up quick, with no potential for reduction. If you check this page I offered some explanations:
