It&#x27;s possible software is the problem here. I have certainly never seen a way to get acceptable quality out of NVENC in common consumer game streaming software like OBS, and I&#x27;ve tried at length including adjusting profiles and tuning settings. It doesn&#x27;t help that NVENC&#x27;s documentation is atrocious.<p>NVENC also mishandles color spaces considerably (full vs limited range), which is a big handicap to begin with.<p>SSIM and PSNR aren&#x27;t really the question here either, the issue is totally perceptual. I do not doubt that on a speed basis NVENC is competitive or outperforms, the question is simply whether you can deliver something watchable that hits under the user&#x27;s upstream cap. If you look at average twitch streams of even mundane video games, many of them are borderline unwatchable - this is a pervasive problem :-) Kicking butt on image-wide SSIM and PSNR won&#x27;t be much use if all the text in a story-driven game is unreadable due to artifacts.
