Optimization issue or cooked CPU?

Hey, first post here and sucks it has to be a somewhat negative one. I recently got back into beamng after automation released a beta for their superchargers update, and have been messing around quite a bit using my vehicles. One of the first things I noticed around 6 or so months ago was a dramatic decrease in performance. I used to average 90fps on high graphics but became lucky to get 40. I upgraded from 16gb to 32gb @3200mhz ram thinking it was memory, which actually gave me around 110-120 avg fps.. for about 2 days. Its back to doing the old stuff again, and whenever I am driving at speed, the game will randomly go into slow motion- without fps drops- and resume at normal speed rapidly even on gridmap.

Heres current specs:
CPU- I7-12700h 14C/20P @ 2.7ghz
GPU- RTX 3070
Ram- 31.7GB @3200mhz

Heres the phys benchmark:

157 Mbeams with 14 max

Just trying to figure out what I got to do to increase my performance in game, right now it feels terribly slow for what I have, and it wasn't always like this. Thanks

 

Might be overheating, check your CPU and GPU temperatures

 

What's with the fatal Lua error in the top right? Some malicious mod?

If it's fine in safe mode (from launcher menu), then it might be that.

is this with Vulkan or Dx11 (default)?
