In your post and screenshots, I only see you talking about trickplays. Trickplays will only get worked on one at a time to ensure that system resources aren't completely consumed by a non-essential task. On Nvidia systems, it will only use the GPU for decoding and the CPU for encoding trickplays. We do not yet support NVENC for encoding trickplays. So there won't be a lot of GPU utilization when you only have trickplay generation going on besides the decoder, which appears to be maxed out.

As for actual video playback transcoding, ffmpeg will always use 100% of NVENC and transcode as fast as possible. And it can already handle multiple users at the same time, up to the software limitation set by Nvidia. Which is 8. But there are ways to remove the limit.
