Fast Cache Access
If you want to jump (in the timeline) you must use the Master Dynamic set cache.
or you can set the dynset to Cache Time Independent.
tP is a simulation system so any operator can modify at any time so
every sub frame needs to come from hard disk, unless the cache is on the Master Dynamic.
You save only the time of expensive operators not calculating...
Master Cache is the final baked solution and gives everything you are looking for.
