+1. Huge RAM previews are not really a good way of working in Vegas. Not completely reliable / accurate and dissappear like bubbles the moment you touch them.

It would be nice to know your version of Vegas so someone with the same version could check.

If you are making such large RAM prerenders, file prerenders or render to new track may be more useful for you.. I would think that much RAM would be put to better use as swap space, as buffers can grow like crazy over an editing session.

Version 16, latest update

I have 64GB, I can rarely get RAM preview to work at all... then there's the performance issues of setting too much RAM in RAM preview and it slowing things down elsewhere. Then the stability issues...

IF your having performance issues then dynamic preview isn't the answer. Your better off using the proxy files and its so easy to use them now.

There is another thread here where we talk about dynamic ram and how the value impacts performance and stability. Some can only get a stable system with it off but for those that can work with it we found that any value over 1GB will actually lead to lower performance, certainly during a render.

For most users 16GB is perfect for Vegas and you wont actually use more than that. For me I have around 3-4 copies of vegas open as I like to move footage from one to another (way quicker workflow than using media bins) so I have 32GB but NEVER has my ram usage gone above 14GB. 128GB is going to be a real waste unless your working on some monster complex projects. and I really mean absolute monsters.

not worth the $ in my book...
