Hi John, and thank you for your input.
I did get this suggestion from a Magix support chap and tried out the Nvenc templates with limited success. I found that (at last) my GPU was beginning to work, but at only 8% activity. The rest of the work (60% activity) was being done by my CPU.
I tried again after your suggestion with the same result. Then I attempted using the Mainconcept AVC as encode mode, but saw zero activity from my GPU.
I have read posts from other folks who are seeing fantastic render assistance from their GPUs, so I still believe I am missing something very basic. Could I have installed the card incorrectly? Perhaps I need to change something in my Windows 10 settings? Do I need to somehow point my GPU to Vegas…or vica versa?
Another concern I have is that some people are experiencing noise being brought into their renders via the Nvenc templates, particularly in dark areas of their videos. This would be as problem for me. But this is less of a problem than getting this expensive piece of kit to function 100% with Vegas!
Further advice would be GREATLY appreciated.
Cheers,
Bruce
