OBS/DBD - GPU usage vs. Recorded Framerate Playback

I didn't want to post this under Tech Support, since it might not be fully related to DbD, and also visibility, but here's the gist of my issue:

Dead by Daylight, while on Ultra, uses 90-99% of my GPU at all times. Whether it's in the background, its framerate is unlocked, or anything else is running, it just buries it. While trying to record 60 FPS, I ran into issues with the unlocked framerate, so I reset to default in-game and dropped my refresh rate from 144 to 120, and then down to 60, since there were suggestions of OBS not working well on a different divisor.

At 1440p, with a downscaled recording at 1080p, I was smoothly playing and "recording", but playback got butchered with a lot of choppiness. Turns out, DbD eating my GPU was to blame, causing 20-28% loss in frames, even though the recording itself is reading correctly. I thought it was odd, but I used GPU-Z to confirm it, and just changing graphics settings drastically altered GPU usage in ways other games would not.

In the end, I fixed this by dropping to High graphics settings, 60 FPS, and 1080p all just to record. While my GPU was dying at 99% usage for no reason other than ticking an in-game graphics preset, my CPU was laughing at 15-20% usage. :|

PC Specs to understand:
OS: Windows 10 LTSC 2019 (64-bit)
MOBO: MSI Z370 Gaming M5
RAM: 16 gigs Corsair Vengeance LPX DDR4 2666 mhz
OS Drive: Samsung NVMe 970 Evo
Games Drive: Samsung Evo 850 SSD
GPU: EVGA GTX 1070 Ti FTWU (never get EVGA GPUs--coil whine!)
CPU: i7-8700k delidded (cooled via Corsair GTX h100i)

I haven't really delved into serious overclocking, yet, since most of what I'm doing right now won't rake in any benefits. Windows 10 has been, as usual, further stripped of features and bloat with OOSU.

Is this issue unique to Dead by Daylight, or have others managed to record on Ultra to 1080p from a higher resolution (1440p in my case)? I don't mind limiting FPS to 60, but dropping my external resolution to 1080p is very annoying, and I'll probably write a script to swap it if there's no easier way around it.

PS: The x264 codec I've used forever seems to destroy renders on Windows 10 with broken colors and vertical artifacts, so that's a huge aggravation, too.

Edits: Clarity, and forgot something in specs.

    Dbd takes 100% of my GPU at all times regardless of overclocks or graphic settings for some reason. I'm playing on low at a capped 80 fps and it still takes it all up. I can barely open YouTube or even the forums.

    I have no problem running anything else in the background (other programs, YouTube, many windows in Chrome), but my GPU will be unable to record at 60 FPS without tanking my resolutions. Mind you, I have no problem maintaining uncapped FPS (didn't measure if it was stable 144, but it's at least stable at 60+) for 1440p, and even when recording for 1080p 60 FPS while stuff is open in the background.

    Dead by Daylight is just unnecessarily using my GPU. I just rebuilt my PC, so I didn't run into this issue before because I was only at 1080p 60 FPS.
