Today in InDesign with large files (e.g. 320 pages, 400 images, many images 10MB JPEGs), presentation mode becomes bogged down with rendering the images and is unusable. Furthermore, using the page view large–jumbo sized views is very slow. On my 5k iMac, I can see that the CPU, the GPU, and the RAM are all available, so there is compute power to be had. Thus the feature request is to enable InDesign to use more HW and/or to have a way to store fully rendered images in a cache.
