Hi,

i use 19 Pro trial and think about make the upgrade on sale, because i really like the gpu accelerated timeline performance compared to Vegas 11. I can add 8-9 heavy fx (blur, lens and color correction, etc) and still see the preview window at full fps, wow!

Unfortunately i have some problems too:
I make 3D stereo videos with two regular cameras, so i have separate left and right files in 1080/50p avchd format on fast ssd drive. I have a dual monitor setup on my 1660Ti card, one for editing, the other for preview (line interleaved LG 3D monitor).

In Vegas 11 i can see my footage on LG at 50fps (full quality, not half), but with latest Vegas 19 i can only watch it at 22fps.
Task manager show my gpu usage which is 62%, video engine 18% and cpu usage is only 43%. So why i cannot see more fps?
When i disable external monitor preview and set my small preview window to 3D line interleaved (full quality), i have 43 fps!
Still no 50, like in Vegas 11, which is a must for smooth editing.

Am i miss some settings or v19 is really worse in this area than 11?
Maybe it's all because of the trial version "VEGAS" watermark overlay?

Tried every settings for ex. optimize gpu, etc. And no event fx at all!

Thanks.
