I've got a VR animation that I decided to leave running and finish. It took almost a week. This was not on a slow machine either, I ran it on a Z820 workstation. With a smaller version (less frames (9 instead of 740)) it will display perfectly well. When I try to load the larger version it will display this, seemingly forever, on both Mac and PC, on almost every browser, both embedded on a site and locally:

Is there a size limit to VR renders? Perhaps I do not need so many frames but I was trying to see the limit of providing a smooth output.
Thanks
