At least on my lowly Lenovo with a GTX 1050 chip.
The problem has gotten worse going to build 452.
I've found that I can consistently hang VP by playing my current project and when I hit the section that has two PIP tracks with Layer Dimensionality going, GPU use hits 50% or so and most of the time VP will start dropping frames (with the frame counter showing ... over and over) and eventually hang.
If I reduce the preview resolution from Preview-Full to Preview-Half, VP never drops frames and VP doesn't hang. So, at least I have a workaround for now. [added later... never mind that workaround doesn't hold up either]
Any thoughts from the Magix crew @VEGASDerek ?
I'm using the latest studio driver.
