Hi there,
I mosty post in the Vegas Movie Studio forum, but for this issue, we're not getting anywhere, so I need 'pro' input.
When using cpu intensive effects, like the cookie cutter, the fps in the preview will drop dramatically. When I check processor use, it stays at about 35 per cent for each of my 4 cores. Is there a way to tell Vegas to use more cpu power for the preview so the fps stays at 25? Increasing 'priority' in Windows in favour of Vegas has no effect, as far as I can see.
Another user made the following observations: "I am just looking at a linear wipe between 2 stills and in the wipe the fps sinks to 6 Fps on my double quad Xeons (Win XP) - while the cpu usage keeps as low as 15 percent - evenly spread on all 8 cpu-kernels. In this example with just 2 simple stills one can not blame 3rd party codecs etc.
It really is strange that Vegas in some cases can not utilize the cpus better - in other cases it is quite Ok.
I am not a Windows expert - but probably the Task Manager does not show the cpu-time spent in api-calls and if Vegas uses a lot of them then the cpus actually are fully loaded - even if you can not see it in the Task Manager. .. just my guess.
Just checked the page-faults and for 10 seconds of linear wipe between 2 simple stills Vegas gets 500.000 Page Faults - that is 50.000 per second - which, of course, will slow down any machine significantly.
One can speculate if the program code is optimal - In my old days as owner of a software company such things would have made me get the programmer into my office ..."
Question: does the pro version behave similarly? Not that I want to buy it, but I can imagine that pro (and I mean 'professional') users wouldn't tolerate this.
