Play and Record at 1440p - Stream at 1080p

[k0ntroversial]

I am currently gaming at 1440p but have the "Output (scaled) canvas" set to 1080p. I'm sick of having 3 output files from each stream as I'm running 2 instances of Source Record (one for gameplay[1440p] and one for my webcam[1080p]) as well as my main OBS output[1080p]. I would rather just have the output directly from OBS be in 1440p rather than 1080p (as it currently stands). My only issue is when I change my Output Scaled Resolution to 1440p and adjust the Output in the Streaming tab to rescale to 1080p, I drop frames as SOON as I hit start streaming.

Is there a way to record 1440p while streaming at 1080p without completely taxing my PC?

I recently watched a YT video of someone that had the below settings, is this possible?

VIDEO TAB

Base Canvas: 2560x1440

Output Scaled Canvas: 1920x1080

OUTPUT-RECORDING TAB

Rescale Output: 2560x1440

PC Specs:
4070TI Super
i5-12600k
32GB RAM

Or should I set both my Base Canvas and Output (Scaled) Canvas to 2560x1440 and then change the Output->Streaming->Rescale output to 1920x1080?
