Vega Pro 23 Rendering not using NVIDIA GPU

I have a new system that includes an AMD Ryzen 9950X, Nvidia RTX 4070 Super, 64G Ram and I can't get better than 8-9 FPS on rendering for YouTube. I manually choose NVENC and I don't see the software using the GPU at all. I used to get 30-40 FPS on a much older system. I also tried rolling back my driver to: Studio Driver 581.57 as recommended in some posts, but no improvement. I used clean install and even used the NVIDIA driver cleanup app before reinstalling. No luck. I should be getting much better performance than this.

It should work- try the h264 template with NVIDIA NVENC and watch it in task manager. It's working here with 581.57 and a RTX 4060 mobile as well as 5070 desktop.

I just tried that and the same thing happens: Almost 80+% CPU usage, no noticeable GPU usage and about 9 FPS. I downloaded Davinci Resolve and got 500 FPS for h.264 1080P. I think I am going to have to look more seriously at that editor. I have been using Vegas Video since the early days with and before Sony. This is really disappointing.

Historically Vegas has been great. This started sometime around the end of last year. Regressing the NVIDIA Drivers did not help.
