Vegas Pro 9: 32bit vs 64bit?
I was just wondering if anyones done any side-by-side tests (like on the same machine) of Vegas 9 Pro in 32bit and 64bit?
I know a lot of plugins won’t work on 64 because there written for 32, but other than that is there much performance difference? Just curious how the two modes compare on things like preview-playback, rendering, etc.

I use both versions regularly: 64-bit is my primary, but there are just some situations where some glitch (at least up to 9b) means I need to pop back into the 32-bit version. Speed? Meh. My impression is that it’s about the same. So why 64-bit? My personal workflow has me pre-rendering to Dynamic RAM all the time and you get more RAM (and longer previews) with the 64-bit version.

I guess I was just thinking it was the OS that could access more RAM. So if you were in 64bit OS, with a 32bit program, it could still utilize the additional RAM, but you’re saying the program gets an advantage from the additional RAM as well.
Very good to know. 9c seems to have fixed a lot of little things, hope it helps you with your issue. Thanks for the response Eric.

I have found that 64-bit Vegas Pro 9.0c, if you consider it 1x render speed as a benchmark, compares favorably in performance to 32-bit Vegas at 1.2x to 1.5x, both running on a quad core 64-bit AMD CPU (separate partitions in a dual-boot 2-drive system).
XP 32-bit, by contrast, with the same version is 5x or greater for the same project.
For BluRay rendering 64-bit quad core with 4 GB RAM or more (my box has 6 GB) is the only way to go, and while you still have available CPU when rendering to do other things with such a config, the BluRay render time is very long indeed (10x or more compared to DVD on the same box, same configuration, same project) for a given length of footage.
