@ColdWeather Thanks for that confirmation that dynamic ram preview is hindering renders with non-zero values in VP 19 for you. @VEGASDerek
I appreciate, you take care of user problems. I have Build 361.
Vegas works fine with H.264x8 sources.
It also works fine with h264 10 bit sources, including the 10 bit 4:2:2 sources from my cameras, though there is no GPU decode (in VEGAS or any other NLE) for these sources.
We have confirmed that the dynamic ram preview settings are affecting how we are using the Intel GPU. We are looking to correct the problem.
Glad to hear you are on it!

I'm sure, you'll find the way!
I was watching my GTX 1060 with 3GB RAM by the Task Manager, and saw almost completely used RAM. Besides, the Task Manager shows what the GPU is currently doing. I noticed, if it shows "Copy" or "Decode", and the GPU load is about 50%, the playback from the timeline is quite smooth, but sometimes the load goes up to 89% while "Decode", and the playback drops down to several fps. What weird is, some short clips being played back can sometimes be smooth (50% GPU) but in the next loop (I mean loop region and Q) fps drops down because of 89% GPU load. Well, this behaviour can tell you more, but I have a question.
I'm thinking about to buy an up-do-date nVidia Card, that should be still affordable. I hope, RTX 3060 would be OK for me. There are some cards with up to 12GB graphic RAM. The questions are, is it better to have more powerfull GPU or more graphic RAM with some cheaper GPU? Are 8GB full OK or 12GB would be definitely better? I mean, does Vegas have any internal limitations when using graphic RAM?
VEGAS likes to have VRAM, especially for higher resolution video or if you are running multiple GPU accelerated functions at the same time. 8GB is the MINIMUM recommended for 4K, so 12GB should give you some comfortable headroom to go a bit higher if needed down the line.
Isn't 8GB the minimum for AMD cards?

Well, now I have Gigabyte RTX3060 with 12GB VRAM installed. The VRAM utilization is about 4.5GB during rendering with H.264 8 bit sources, the Task Manager shows Decode and Encode activities of the GPU: decode at about 15% load continuously, and encode as periodical triangle spikes up to 85% load.
The rendering/timeline playback speed depends not only upon the sources but obviously upon the project itself. For instance, I make videos of soccer games (kids) inserting the current score (text track, picture-in-picture, scaled and placed with an offset) and play time. The soccer play time is a separate video file that is placed as picture-in-picture in an additional track, scaled and moved to the top area of the screen, and that is, that essentially slows the rendering/playback: muting this track, the playback runs almost in real time (59.9fps) while upon activating the track the playback drops down to about 15fps. The rendering runs at average 12-13fps (against 6-7fps with the old GTX 1060Ti 3GB before).
What also positive is, with the new 12GB graphic card and having the dynamic RAM at 50% (of my 16GB CPU RAM) and 32 threads set I have no more crashes while rendering which I reported before in this discussion. It seems, too few VRAM (3GB before) was processed by Vegas not properly and made it crash.
The new graphic card does not accelerate for my original H.265 (hvc1) sources in 10-bit depth, though.

Voukoder may eliminate the spikes, increasing render speed, cpu and gpu use
