I have had a similar issue with performance and FPS instability.

I’ve experienced performance issues and FPS drops. Using MSI Afterburner, I noticed that during the drops and instability, the CPU usage would spike to 100%. The CPU usage was very random, it could be at 20% and then suddenly jump to 80% or 95% in an instant.
I managed to mitigate the issue by switching the API from DX11 to Vulkan. Now, the maximum CPU usage is around 30-40%, and the FPS drops are less frequent. I’m not sure if the issue is because DX11 overloads the CPU or if Vulkan disables some process, but in my case, DX11 turned out to be the problem, preventing me from playing properly.
