CPU Performance. Every thread stalls?

Hello,

I have huge issues with performance and I cannot figure out how the profiler (Session Frontend) works.

Every thread just says stalling or sleep. I looked into other questions here and figured out I basically just have to look at the RenderThread and the GameThread.

However when i look into these it STILL looks like they are just stalling. Can someone help me understand this? I will attach my stats file. I tabbed two times to start and end the profiler so you can ignore the spikes. Im looking into my normal performance.

I uploaded my file here

Thanks in advance !
