Greater GPU use means more hanging

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.

I threw a bunch of clips at it- DJI Osmo 30p, DJI Phantom 4K, Sony a6500 AVC S120p, regular Sony a6600 4K AVC, Canon T3i 1080p in a 4K timeline at 24p.

20+ minutes later, my system is up only 100mb of ram usage from the start. I stopped the file and now I am 300mb under the usage at the start. I closed Vegas and the process is gone and memory returned.

(Dell XPS 9560, NVIDIA 1050 4GB, 32GB ram VP 17 452. NVIDIA decoder and Dynamic ram preview set to 0).

Same here. When I try a 4K AVC video from my camera, and some other 4K clips I found lying around, I cannot replicate the memory leak. It looks like that Hawaii clip I randomly downloaded from the internet just happened to be the one that causes VPro some grief.

Yes, that is my situation also, in real world use, it's rare for me to have the memory leak normally, although I did today, and vegas has never almost crashed my computer like that clip does when I loop it in your test. It seems true anyone that it does not happen to just does not correctly follow your instructions, and like roger did used their own clips

It may be niche for us, but for another, due to their media, it could be a constant problem, and you see as much with people who report running out of memory, only for others to discredit and shame them by saying they don't see such problems with their files. but is not the same

@Former user If you see anyone having a repeatable memory leakage problem with their files, please have them post it here so we can test. Nobody is going to discredit or shame anyone.

I'll add a data point. I am not seeing this after 10 minutes with the system in my signature. RX480 8GB.

Would someone who has the failure try this re-wrapped version of the file?

I'm seeing the same as John, playing more than 2 hours 4K HEVC and further 😶

Your re-wrapped version does not produce the memory leak. The original version still produces the memory leak for me. But your version is shorter than the original!

@KenB

I haven't found an application that I use that plays any video past 09:25 from the original file even though Mediainfo declares the time is

Duration : 10 s 444 ms

Just confirming, the dodgy Hawaii 4K clip referred to in this post still has the memory leak in VP 18. Not that it matters, because it really was a dodgy clip and no one has been able to reproduce a memory leak with any other 4K clip.
