Hi,
I have been seeing bad stutters with the A300. I have a 7800x3d, 4080 super, and 32 GB DDR5.
The stutters are really noticeable when I am panning the camera or change instrument views. They also seem to occur even when I turn my graphics settings down. For example, I was seeing them with my TLOD set to 10, and DLSS set to Ultra Performance.
I grabbed a screenshot with the developer mode fps display showing. This was with a render resolution of 1280x720.
I was flying over Newfoundland, Canada at the time, outside of any major cities. Air traffic, road traffic, and airport traffic were all turned off. I also removed my navigraph plugins from the community folder.
