Yes, the bottleneck is certainly I/O bandwidth: in fact the application doesn't block until It work totally in ram. When RAM is full the paging file (on the hard disk) begin to grow and the application go slow and crush. > Still: the resolution you mentioned (1440x1050) requires ~108 MB/s for 8-bit > RGB @ 25 fps > (and over 140 MB/s for 10-bit or RGBA). You need a few drives to do that... What do you mean with "You need a few drives to do that..."? That the majority of hard drives support a flow like that? I think so but probably the problem could be the loading process of images and I hope that it could be resolved using other techniques (probably customizing implementation of osgDB::readImageFile? probably with ramdisk?). Is it possible or am i wrong? What is the path (in terms of memory) that images follow before to be displayed at video? At the moment i'm already trying using quicktime (inserting images in a .mov) while, as regards ive, there could it be a problem of size because i have a lot of images to display.
