OK, I guess I should start with some background. I have a 7800X3D CPU, RTX 4090 GPU, and 64GB of 6000hz memory. I am using AutoFPS with FPS Cap, FPS set to 35 in AutoFPS, Max Framerate in sim, and Dynamic Settings in sim.

All of my testing is with the Beachcraft Bonanza G36 Mod.

What I am experiencing, in both 2D and VR, is that certain functions, when invoked, cause a stutter, while during normal straight flight I do not have stuttering.

For instance, I take off just fine. Right after takeoff, I hit the control to put up the wheels. That causes a stutter. Then shortly after I hit the control to put up the flaps. That causes a stutter. Opening the toolbar and doing something from there causes a stutter.

Looking at GPU-Z I do not see any resources maxed out.\Can anyone provide any insight that might help me understand why this is happening to me with my system?

Since it happens in both 2D and VR I put it in this part of the forum in hopes that more people will see it and perhaps have some guidance for me.

 

Thanks everyone. Looking forward to getting your responses.

2020 or 2024?

I think this (in bold) may be the problem.

The in-game dynamic mode is known to be dodgy and not many people use it (from what I've read).   Plus, AutoFPS does exactly the same job (but tons better), so it may be that both are conflicting - eg. AutoFPS and the in-game dynamic mode could be setting values at odds with eachother - in real time.

So as a starting point, I'd try completely turning off the in-game dynamic mode, and try running just autoFPS.

You could also try setting the vsync setting in 2024 to "half refresh rate".  This was the single biggest factor that eliminated stutters for me.

Good luck!
