Catchy title always does it …
I would like to push the max out the encoding capabilities of the GTX 10xx series.
When I use these parameters, the GPU is at only 35pct, so there is headroom to push it more and probably to improve quality.
What can I improve ?
(by the way, it is live encoding that I need)
