Somehow I knew you would be the first with answers :)
Have you done any performance tests? I noticed Axon has now the same content specs as DL3 highend.com/support/digital_lighting/CreatingCustomContent.asp So the standard is now 1024x768 Have you tried creating video with higher resolution...even at HD resolution. Is there enough horsepower to run video with higher resolution. Though I know there's not much point to go above the native resolution of output unless it gives an advantage when zooming the video.
I have used a file that was 1440x1024. However, there were some downfalls.
If you run a single layer, you'll be ok (not the greatest performance, but that was expected). When we tried to run 3 layers of this size file, it choked big time (like I knew it would).
We had the files re-rendered at 1024x768 and the animation folks couldn't tell the difference. :-)
Your hardware version also makes a BIG difference...if you have the older Pentium-4HT motherboard and older 80GB HDD and old RADEON 850 card the server peformance will be nowhere near what the newer Core2Duo motherboard is capable of with the 320GB HDD and RADEON 1900, 1950 or HD 2900 card.
The standard spec has not changed...the stock files are all 640x480, but the output is locked at 1024x768. Which also happens to be the native resolution of the projectors inside DL.2 and DL.3
