But yeah, I checked OBS it's already set to NVENC and I had a feeling that downscaling/upscaling did in fact cost more resources to have to process that stuff.

EDIT: Checked their Inspector tool and it said "Excellent" streaming quality and it said that my last stream was between 4,500 and 5,900 kbps. Willing to guess that the 3.5Mbit thing is outdated info. But thanks for confirming that up/downscaling does indeed require more work than just doing native resolution.
3.5Mbit might be stale.

Encoding Profile: Main (preferred) or Baseline
Mode: Strict CBR
Keyframe Interval: 2 seconds
Framerates: 25/30 or 50/60 frames per second
Recommended bitrate range - 3-6 megabits per second
The vital part there is CBR. Onboard encoders tend to do CBR better than VBR, but will default to VBR with the assumption you're transcoding video on disk.

Enable Advanced Encoder Settings : when checked, new
options for Encoder available:
◦ Enforce streaming service bitrate limits : if checked,
default maximum bitrate for selected streaming service
should be applied instead of value specified on this tab.
Some blogs on this say that Twitch will shutdown streams that are at 6Mbits.

So I don't know, I guess it depends if you have a partner/paid account.
