Formula Pro and Spa

Hi all, I have an issue with new formula pro racing in Spa, all official content. I get frozen screen playing offline when I am close to the start/finish line, I've tested the car in othe track and it works perfectly, other car this track and perfect too, no idea about how to solve. My specs i7 10700 - gtx 1080 - Rift cv1

 

Nothing?

 

Do you know if there is a peak of CPU or GPU?
fpsVR is very useful for that

 

Thanks for the answer @lagg watching afterburner there is a peak in cpu8 or similar number, without IA drivers and turning down circuit detail from high to medium seems to fix the issue, but I think my pc would be powerful enough to deal with this, I have 90fps as a rock the whole lap, there must be some kind of conflict there.
I expected some help from Studio397...

 

It's possible that at this moment some circuit objects are loaded.
Have you tried to reduce the circuit detail one point?

 

Yes, I told in the last comment
