Steve , I did not try an AM yet because I am awaiting your opinion ... 

Without AM , but with addons via Proces Lasso it is already running very smooth. However these addons are still grouped  across my 5820 cpu like it has an AM of 340..

v4 is much smoother anyway because it's not shuffling memory around and doing so much I/O as v3. Continue using Proc Lasso as you do, AM 340 is the same with v4 as with v3.

Now I understand. I limit my frame rate in-sim to 30. I know from testing that the new card is capable of much higher frame rates in non-complex areas. I assume that with P3D Vsync I would normally get 60 FPM unless the graphics workload gets too high, in which case it would throttle back in 1/2 multiples of 60 - to 30 or 15 etc.

Seems to work fine as I currently have it. I think I will leave Vsync off for the time being.

VSync=On goes with the fps lock slider set to Unlimited and the renderer relents at around the frequency of the monitor, it will not steer toward lower frequency sub-multiples, it will continue unlimited. The fps lock is not a limit because the renderer continues making the next frame, or the next buffered frame, as soon as the last is finished, it never relents. Setting Triple Buffer=On when using VSync=On with Unlimited the renderer relents after the third buffer.

I think this is what I am doing after we last talked and led to 100% smooth performance.  What I am doing is FSP slider to UNLIMITED and monitor set to 30mHz refresh.   Now if frames can't be maintained at >= 30 it gets very choppy, worse than all other configurations I've tried over the year.  But again, if 30 is maintained then it's 100% fluid panning, flying everything.   My GTX Titan is feeling it's age so I have to monitor GPU utilization and if it starts approaching 100% I have to stop the sim and dial back some of the controls in the Lighting group which greatly impact my GPU, typically shadow distance sliders, shadow quality.  Seems someone could make a utility that does that in realtime per user preferences configured in a dialogue, ie does what I do when I stop and adjust.  It could work because I notice the screen doesn't need to be redrawn when changes are made to members of the Lighting group.
