Guys,

I think v6 is quite optimized because even with a default install and pushing the pushy sliders full right I have more or less acceptable performance, but simmers have this optimization stress that keeps making them wonder how to get even smoother rides, so, as I had previously had v5 installed and followed some well known optimization receipts I tried the same with v6 but... :

1) When I disable FPS limiting ( Unlimited ) and set VSync to OFF in the P3dv6 Graphics options, and set Adaptive VSync and/ or FPS limits using NCP, in the sim using SHIFT-Z to monitor FPS I see it varying wildly, sometimes way above 30 fps (my monitor is 60 KHz) ?

2) If I enable VSync AND limit FPS to 30 in the P3dv6 Graphics  options, the FPS do look a lot more stable, and never above 30, but I read that setting it this way taxes the CPU and not the GPU.... Well, I don't notice my CPU running hotter, so I wonder if P3dv6 is already optimized to hand to the GPU what it can better take care of, but I'm not sure about it, so, should I still disable VSync in sim, and set FPS to Unlimited, and then set Adaptive VSync in NCP and or limit the FPS there?  But why do I still see, when I do this, the SHIFT-Z-reported FPS varying sometimes well above 30 fps ???

3) I only use "TAA" in P3dv6, and set no AA in NCP, and I think TAA des a very good job, but regarding AF (Anisotropic Filtering) and based on v5 recommendations, does it still make sense to disable it in sim (appears as Trilinear when I set it full left) and use AF in NCP instead ?

4) I've also seen users recommending to disable VSync in sim and NCP, and use the in-sim FPS limiter only. For my machine and monitor (60Hz) I would limit in P3dv6 Graphics the FPS to 30. Would this be a better option ?

Thanks for any hints... I'm kind of lost regarding this aspects of setting it in the sim loading the CPU and not the GPU, and I really can't understand why when I set VSync and FPS limits in NCP (Adaptive 1/2 VSync) the displayed FPS values in the P3dv6 sessions sometimes show numbers well above 30?

I haven't yet installed v6 so can't help on the specifics, but have you posted in the LM P3D forum? Initial responses will inevitably come from the one or two permanent residents of that forum and are not always helpful, but others usually follow with practical advice. LM do occasionally show an interest in their forum, but this has regrettably become quite rare. However it does appear from the successive patches that bugs are being noted and corrected.

Unlimited in sim, vsync on, locked externally at 30 (my monitor is set to 30hz) works for V5 and V6 for me.

Before using NCP (Nvidia Control Panel) settings, make sure to go to NCP "Manage 3D Settings" first and in "Global Settings" tab choose the "Restore" button to factory default the settings, and then in "Program Settings" tab choose the Prepar3D.exe profile and again choose to Restore the defaults to that as well.

Now, only use NCP for making settings that are unavailable in Prepar3D.

If a setting is available in Prepar3D use that primarily, and for settings not found in Prepar3D but are found in NCP use the Prepar3D.exe profile in "Manage 3D Settings" "Program Settings" to set those.
