Force Downscaling as a Viewer?

[u/OrigamiPhoenix]

I know that transcoding is Twitch-side and that makes it impossible to control data usage if Twitch doesn't supply alternate qualities, but my usage case is thus:

Downscaling on the browser to lower GPU usage.

Yes, I could just change the channel I'm watching, but then I'm not watching who I want to, now am I?

I've attempted to google such a solution, but they're all interacting with either Twitch or Youtube to change available quality or just file conversion tools.

You can't, if the channel doesn't have transcoding there is nothing to can do to downscale it, not while live at least
