I suggest you try in nVidia Inspector;

 

1. Turn on Vertical Sync Smooth AFR Behavior to 'on'.

1. Go from a Frame Pre-Render of 3, to the max...8

 

 

The first setting was first exposed officially to the end user in the 313.95 driver, although NI has exposed it before. Under Vertical Sync, it is listed in the nVidia. Control Panel as "On (smooth)". It is designed to reduce micro stutters and according to nVidia, it is only for SLI. Here's the quote from the Geforce forums:

 

"When SLI is active and natural frame rates of games are below the refresh rate of your monitor, traditional vsync forces frame rates to quickly oscillate between the refresh rate and half the refresh rate (for example, between 60Hz and 30Hz). This variation is often perceived as stutter. Smooth Vsync improves this by locking into the sustainable frame rate of your game and only increasing the frame rate if the game performance moves sustainably above the refresh rate of your monitor. This does lower the average framerate of your game, but the experience in many cases is far better."

 

The second setting is only used if Vsync is off. With Vsync on, double or triple buffering is used.

 

But you never know with video driver settings.

Hmmmm.... I simply got a single stutter which happened about every 30 seconds since using prerendered frames of 8. I've now corrected it by returning to my previous setting of 3.

Sorry to read that, Rockliffe.  After reading your comment, I set my limit back to the standard 3...and fired up FSX.  I got right back to micro-stutter and the occasional long stutter as scenery updated.

 

I shut down FSX, went into nVidia Inspector, ran the setting back up to 8 pre-rendered frames, and started FSX.

 

Smooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooth.   I once again had that visual that your plane is actually floating upon the air currents, with that very slight up or down upon those currents.  If a system has any kind of micro, or macro frame stutter, you will never enjoy this visual reality.  I guess it all (as always) depends on the user's system spec's, what driver suite edition they are using, etc.  I will say that I have had the best performance so far with the latest nVidia driver suite. Even under moderate cloud base served up by OPUS, I stay around my locked down 30 FPS.  This is with Scenery Complexity and Auto-Gen set to my (never to move again....) Very Dense setting level. All, in all, I am finally after years of tweaking, and what-not, at a very stable and most excellent visual rendering.  I can complete hours of uninterrupted and visually stunning (aka realistic for the real world detail) flights, as I have for this week, since discovering the magic recipe for success....  Good flying, Rockliffe, no matter what the settings are to get you there.... !
