I don't want to stream in 1440p. I want to record locally in 1440p, and stream at 1180p (or whatever it is after the ratio I apply) as usual (twitch can't handle my 1440p upload).
*1152p after 1.25 res downscale
Oh I see I must have misread something, somewhere. As you say it would probably be worth considering going back to 2 PC setup, less stress on your system and hardware.
