GPU Utilization Drops

[fullheartedgamer]

After attempting to determine frame rate loss and unnecessary lagging, I have been able to identify that a large portion of issues are being related to the physics engine running through the GPU and the utilization of said GPU will become choked if the perceived framerate exceeds what the engine is calculating in comparison to the GPU. 

 

This could be part of the engine to ensure that the engine physics can't run away with GPU utilization and cause damage or overheating on the cards. 

 

Full utilization can happen in the game with smaller vessels and when out of Kerbin, but why would the utilization drop when needing more resources due to the number of part, physics calculations, etc. 

Is this something that is being looked into or are we expected to see this resolve with the future patches and updates? 

Currently running these specs:

AMD Ryzen 9 5900X 12-Core Processor               3.70 GHz

EVGA 3080ti 12GB

64 GB DDR4 3200 MHz Ram

Please let me know if there are any tips or if there is any other information required.

Forgot to add Full utilization is possible, just opposite of when it should.

Physics doesn't run on the GPU.  What you're likely seeing is the GPU sitting around with nothing to do because the CPU is taking too long for the larger more complex vessels.
