I upgraded my RAM last weekend to 3 GB specifically so I can better use VMS, and *then* I installed my purchased VMS8-plat copy. Here's what I get now: Windows can use and utilize 3 GB of RAM, but VMS8 can only see 2 GB. Here's proof:

This can have a bad influence in the way the application deals with heavy HDV projects because it might think that it ran out of memory while it hasn't, and bail out. I don't think that 2 GB RAM is a limitation of VMS compared to Vegas either, because simply, some HDV amateur projects are so heavy that putting a cap on 2 GBs would be criminal.
