I’m not sure how recently you installed windows fresh or if it’s an option and install nothing but msfs. I recently found my constant stutters on my 7800x3d were caused by the first thing I install after windows 11 which was MSI afterburner. When set to monitor things like GPU power, it somehow causes stutters every time it polls the gpu. I had set it to poll every 100ms so you can imagine what a stutter every 100ms looks like not good.

I checked on that, it was set to 1000ms (default) for me. Also shutting down Afterburner has brought no change on the CPU load.

For me at the moment, the only option that seemed to draw a lot of CPU Power (MainThread Time) was ironically any option for Motion reprojection exept disabling it completely…

With fairly high settings I am now sitting at around 25-30ms MainThread time (mostly yellow) and GPU aroud 25 which is ok for me. I still wonder if I’m doing something wrong here. But at least I get around 35-36 fps in VR with this in my test scenario but with dips to mit 20ies depending on the direction I look at…

If I find time, I will test a fresh Windows Installation but I lost so many hours experimenting with all the tools and settings, I find it hard to motivatie myself to do it…
