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 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 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 uses for caching. In complex designs, some cacheable objects will not be cached if there is insufficient memory to do so.
