Very pleased with this new update; thank you for adding support for USB storage. Seems to work quite well. The only nitpick that I have, though, is that it seems like Skybox software doesn't read, or buffer or whatever, files from the USB drive quite as fast as it does files saved on Quest 3's internal storage. This is despite the USB-C port having more than sufficient data transfer capabilities, and my USB-C flash drive device advertised as 400 MB/s read speed. It works fine for the large majority of files, but, for whatever reason, it seems like those really dense files (e.g. 60 Mbps bitrate) are not read quite as quickly. Buffer speeds displayed to the screen, while buffering, were typically in the 1-3 MB/s range, which is indeed too slow for 60 / 8 = 7.5 MB/s bitrate video.
Also, seems like some files (types) were unable to be read at all. For instance, an AVI file could not be played (it was the only AVI video that I had on the USB device, so I don't know if all AVI files cannot be played, or just this one).
IMAX environment is cool, and a thumbs up for the other features (anti-aliasing, sharpness, optimized Pro-HD quality, etc.)
(P.S. I don't know what "image display time" is.)
