PC [BUG] Unusually high CPU usage and temps (Fixed with a workaround)

I just started checking out the latest 1.5.4 update on Steam and noticed unusually high cpu temps (60°-70°) when playing SDV with a Ryzen 5800X and I thought to myself, SDV can't be this demanding. What I observed and things I tried to fix this:
  • One thread is pegged at 100%.
  • In-game v-sync on and off => no changes
  • v-sync setting from the nvidia control panel on and off => no changes
  • Setting my monitor to 60Hz and 120Hz => no changes

Then I monitored my fps with RTSS (https://www.guru3d.com/files-details/rtss-rivatuner-statistics-server-download.html) and saw that it hovered around 61 FPS. I then limited my FPS to 60 through RTSS and it seems to have solved this issue. CPU temps are down to ~35°C, the game felt a lot smoother the thread isn't pegged at 100% anymore.

Maybe the way SDV attempts to limit the FPS is broken or something?

My specs:
  • Using a Switch Pro controller
  • Windows 10 Pro latest updates
  • GTX 1070 (Driver version 457.09)
  • Ryzen 7 5800X
  • 4x8GB 3600MHz CL14 G.Skill TridentZ RAM
  • ASUS ROG PG278Q 144Hz 1440p monitor (set to 120Hz)

I can confirm these same findings.

- Windows 10 Enterprise latest updates
- GTX 1650 (mobile) Nvidia drivers 471.41
- AMD Ryzen 5 4600H (6/12 mobile cpu)
- 16GB Memory (2x8GB DDR4)
- 3 Monitors (only one of the is running SV), MSI G27C5 (Set to 120Hz) (the other two are set to 60hz, but they're side monitors, not the main one).
