Excessive CPU and GPU stress. Code optimization done incorrectly?

Hey I’m jumping on this topic, I didn’t play MSFS2020, I am playing 2024 with a VR headset, I keep having a crash during the game (last 2 times I had it were on the same mission at the same moment (short final RW36 in Trento, italian alps, I checked on MSI afterburner and I had a huge spike to 100% usage during the crash (but it seems it was 3-4 seconds after it froze) at 2 specific cores (especially core number 3).
If I understand correctly, it’s either because the GPU isn’t my bottleneck (and I’m not sure I understand how to fix this), or there is a specific crash on this approach, but I was also having other issues (which seem more GPU related if it isn’t the game that is just not VR ready for non-NASA PC (I have a 3080ti and an i5-13500))
