Friend is having trouble editing 4k with Vegas 17 on Win10.
He just upgraded to a i7-9700 CPU yet is still having performance issues.
Preview is still slow and laggy without making a preview/proxy file
Yet, I have a similar rated AMD CPU and have no issues editing without a proxy file.
He also has GPU acceleration selected.
Are there any settings he can tweak to get reasonable performance commensurate with his fairly powerful CPU?
My 4k HEVC files at 200Mb/s are too large for my 8700k, so I would say it's probably not much better with a 9700k due to the benchmarks. How many cores does your AMD CPU have?
I have to manually encode a proxy file to edit anything I do - else it's a CPU bottleneck issue and I get like 10 fps max. You could try h.264 1920x1080 and then replace the file in the timeline with your 4K one and then render when you are done editing.
My Ryzen has 6 cores. His i7-9700 has 8 cores.
I think we found the issue. Under Preferences -> Video
He set "Dynamic RAM preview Max" to use all of his avail. RAM. !!
As soon as he would preview play a video, his RAM usage would spike to 90%+.
I told him to put it back to 200MB, and it seems to work fine now.
What exactly is that setting about ?
Now, his PC edits and renders the identical files faster than mine.
I also told him to reduce his bitrate from 42mm to 10mm, for even faster render times.
I can't find an answer to that quickly (besides a claim it has vegas reserve that memory for itself) but I did see many people saying that setting it to 0 (or lower than what it was) after you're done editing decreased their rendering time significantly. They say to put it back when you are editing.
There seems to be some good explaining about this feature on this page:

What exactly is that setting about ?
That setting is to reserve an amount of RAM, only for the use of this option in Vegas after you selected a part of the timeline as a region:
That amount of reserved RAM is not anymore available for other tasks in Vegas.
Why do you ever need to build a dynamic RAM preview?
I just have my Preview->Full set and can preview fine with no adjustments.
Was this feature for older/slower builds that had low RAM?
If you added transitions and plugins for more than one track each hardware cannot play that at full 4K HEVC preview, therefore you can select a certain region of the total timeline to play it as was it rendered already.
Since I don't add effects, I don't need RAM preview? I sometimes add FX brightness/contrast. But, I don't need to see if it the preview.
I don't need RAM preview?
It 's up to you.
If you don't need it (as I do) the setting can be at default or 0
But, to summarize the feature, if you have a complicated effect, the PC may have issues previewing it? So you press SHIFT-B to pre-render that section in RAM, so you can preview it? Is that the basic idea?
Also, stuff like brightness/contrast FX is simple and does not require RAM preview, right? Just complex stuff like transitions or animations?
I know what the program does and therefore I don't need playing it as it is.
Looking at the picture when placing the cursor somewhere on such a piece of the timeline is enough for me to watch if I made the right choices.

Yes, but the standard reserved amount of RAM (200MB) is almost nothing for prerendering a high resolution part of the timeline (less than a second). In case of a needed smooth preview of a highly complicated part of the timeline the "Selectively prerender Video" SHIFT+M is a far more better option (and only a little slower than Dynamic RAM preview, to generate) because it prerenders a chosen timeline selection with a chosen codec and remains in your timeline as long you don't change anything to that part of the timeline. Those previews remain also when closing and saving your project.
I don't add effects to my videos, but want to understand these options.
Can you tell an example of what to add a transition or effect that requires use of dynamic RAM and/or SHIFT+M ?
For simple editing you will not need both. When you make compositions where multitracks are involved, like a virtual choir, you definitely will.
Choir. Like playing 2 vids/tracks at the same time?

Not direct 2 vid/tracks but something like this: https://www.vegascreativesoftware.info/us/forum/75-pip-or-similar-for-virtual-choir--125511/#ca781149
Ok, so embedding multiple videos into one screen, like the Brady Bunch intro
