Cache Control
Complex objects including layers, groups, bevels, shadows, blends, molds, contours,
ClipViews and Live Effects can be cached as bitmaps when they are rendered. This
means that the next time these objects need to be redrawn, the bitmap can often be used
instead of re-rendering the objects, making redraws and object drags very much faster.
The difference is particularly noticeable with complex documents.

Since caching involves storing additional bitmaps in memory, it has the potential to
increase the amount of memory used by Xara Designer Pro X significantly. Therefore in
this dialog you can turn caching on and off and you can also control how much memory
is used for caching when it's turned on. Increase the percentage memory figure to make
Xara Designer Pro X cache more objects in your design, generally making redraws and
object drags faster at the expense of larger memory usage. Or reduce it to lower the
amount of memory that Xara Designer Pro X uses for caching. In complex designs, some
cacheable objects will not be cached if there is insufficient memory to do so.

This dialog also shows you how much memory is currently being used for caching.

Live drag is described in Document Handling (on page 37).

Note: Cached bitmaps will only be used during object dragging if you use LIVE DRAG. If
you have LIVE DRAG turned off, then as you would expect you will just see the outlines of
objects when moving them.
