The appearance of stutter (and how much/how severe it is) has long since been proven to be a factor of where you fly, when, other aircraft involved and quite frankly other things which seem to remain unknown at this point.
No one has ever proven that, in a proper test, the stutters can be effectively controlled. They can be reduced by settings in some cases, such as listed above: other planes involved, terrain, and so on. But it is still absolutely a matter of fact that they cannot be eliminated. When you see videos posted that appear to show there are no stutters, it's simply because they are not encountering the conditions which would otherwise cause said stutters. Without doubt, the exact same system/configuration will show stutters if subjected to the right test.
No amount of altering settings or configuration will change this. No amount of money spent on hardware can change this. No amount of testing has changed this.
As Major McGee explained above, there are limitations in this sim which cause the stutters that are often mentioned, and no one's ever been able to change that. Most will agree that doing so is not possible. This is known all the way back to CFS3, where it was established many years ago that repeatable testing was absolutely essential in any effort to improve performance (stutter was an issue then just as now, this is also well documented).
Many people advocate just accepting the limitation and enjoying the game as is. Absolutely nothing wrong with that, if that's your choice. Nor is there anything wrong with calling it as it is. Those who choose to accept it have every right to do so. Those who understand the limitation and call it what it is also have every right to do so.
