Hi, I've been using VMS11 for a few years on a 64-bit machine, and realize its a 32-bit program, so I'm limited to slightly less than 4GB of RAM usage, even though I have 16GB installed. I just have the standard Intel graphics (4000, I think) card, so nothing special there.
So last night I downloaded and installed the latest 64-bit version 14 (build 87) and did some rendering on a simple, short HD video of about 10 minutes length. To my surprise, version 11, utilizing 3.5GB of RAM rendered the video in 9 minutes. When I rendered the same video in version 14, at the same settings, it utilized 4.5GB of RAM, but took 14 minutes. Both programs are in more or less default settings, I haven't tried to tweak anything to affect performance on either version.
Why didn't version 14 utilize more RAM, and why did it take LONGER???
BTW, its a i7 CPU, 3rd generation, forget the exact version, i7-3770 maybe. Not on that machine at the moment.
EDIT: see screenshots in later post, problem is related to rendered bitrate being wrong
