Long shot attempt to help you from a non IT expert. I also recently had a severe stuttering issue. Any chance you have malwarebytes running in the background? If so, turning it off for me immediately solved the stuttering. Maybe other security softwares have similar effects on msfs but some Im trying now have worked much better with the simulator. Best of luck solving this.
A couple screenshots of fps with and without malwarebytes:
Main and RDR thread usage indicates IO and CPU bottlenecks. Turn off Online Functionality, test again. Turn off ALL AI activity in Traffic. Test again. Also, if you are using a third party performance monitor the sim has to pass the frame to the 3rd party application before it gets to the screen. Turn off 3rd party system monitors.
Does sound like your CPU bottlenecked so not sure any setting change is going to make a difference.
Only thing that will fix it is a CPU upgrade.
Though I will say does seem to be an issue with performance when editing in the sdk where performance degrades over time seen it drop to 10 fps few times, I don’t have the issue when running sim in normal flight.
Just to check are you running it on dx11 or dx12?
similar to what was said above just make sure there are no unnecessary programs running at the same time that are using up CPU resources.
I recently upgraded to 3080ti + 1000w PSU but its paired with an i9-9900k which is 8 core seems like a good combo in games tried it on so far.
This is really interesting! I did my own legwork to select parts for my Flight Sim build based solely on hardware reviews and speculation prior to the game’s release, but it turns out, according to this calculator, that I nailed it:
Now, I still had a lot of trial-and-error science to do when it came to optimizing settings and figuring out which sliders do what (see the link to the thread I posted just above), but I feel like my experience has been better than most.
