I know that rendering shouldn't be faster in Vista 64 bit than in XP. I know that Vegas can't utilize more than 2GB memory, etc, etc., and I never expected it to be. In fact, I actually expected slower rendering times.

But I swear it is faster, or seems to be. I rendered a 51 minute project with some grandient effects in 16 minutes, which is a record for my workstation. Without the effects the render time would likely been 14 minutes.

Has any else had this experience?

I can't really comment on Vegas' memory management, but all 32-bit applications can address 4GB of memory, it's just that XP can't give 'm that much (being 32bit itself). In Vista "WoW" can give applications access to the full 4GB, and as long as there is enough physical RAM, you should see an improvement in applications that heavily use memory.

Thanks George. I am wondering now if when I have read that Vegas only uses up to 2GB memory if they were referring to the OS limitation, not a Vegas one. If what you say is correct, than my 32 bit apps "might" benefit from increased memory usage, since I am running 8GB RAM in a 64 bit environment.

Other than rendering everything else seems about the same.

Just check out task manager or resource monitor, they will show you how much memory an app is using (ctrl-alt-del).

Of course. thanks George.
