Should you use Nvidia inspector

Sounds odd, make sure to recreate the profile, that's normally the cause of strange results.

In FSX we can switch the filtering off completely and see the very obvious banding in the sky, but there's always a degree of filtering in P3D, so it could be you have some other issue.

I stopped using NI after P3Dv2.3 and haven't really missed it.

I had all sorts of issues with stuttering when I first installed P3D

 

I ended up resetting the NI profile back to defaults as well as the Nvidia Control Panel.

 

All I have now is Vsync to Adaptive in CP and 2 X SGSS in NI. Nothing else is adjusted. I thought I could use the settings from FSX DX10 but it wasn't the case.

 

I found with P3D less tweaking definitely seems to be more

Hi Steve

 

I applied your NI settings last night.  A vast improvement visually all over.  In fact, its the best I've seen P3D on my system since i got V2.  However, my frame rates have tanked somewhat.  I have my limit set at 30.  When parked at OMDB last night, in the VC i was getting between 15-25 fps and my Track IR was very laggy indeed.   External view however, not so bad at all.   I'll test some more this evening and maybe turn down some of the settings in NI.   But nonetheless, I'm glad I've returned P3D to something somewhat resembling my FSX setup.

 

Now I'm thinking of  upgrading to 2.5 as I'm still on 2,4.  There seems to be alot of positive response about overall smoothness in 2,5.

Erich, have you tested using unlimited frames ?

Hi Julian 

 

I haven't tried running with unlimited fps yet.  Hopefully that improves things somewhat.

 

I also installed EZDOK last night which I was very happy about, but couldn't imagine that it would be the cause of laggy TIR

Also trying to find the sweet spot...but I'm not satisfied with the image quality of the suggested settings.

 

I have a very satisfactory result using the following:

 

------------------------------------

Prepar3D:

 

FXAA: On

MSAA: 4x

Texture Filtering: 4x

Texture Resolution: High 2048 x 2048

Vsync: On

Triple Buffering: On

Frame rate: Unlimited 

 

Nvidia Control Panel:

 

DSR: 2x, Smoothness: 20%

Maximum pre-rendered frames: 3

Multi-display/mixed-GPU acceleration: Single display performance mode

Texture filtering quality: High quality

Triple buffering: On

Vsync: Adaptive

 

Nvidia Inspector:

 

Default - no settings

 

Prepar3D.cfg

 

Default - no tweaks

 

------------------------------------

 

 

These are not any "scientifically driven" kind of settings, but a trial and error attempt trying to find a smooth result.

Maybe it would be good to try using a frame rate limit inside P3D.

 

 

Try it and report back if you like...If we ever find that graphic's nirvana..we'll all be happy.

 

I am in a position that I am not sure if smoothness is more important than graphics. When you see what you can get with these settings in terms of image clarity, you think that you "saw the light" and anything else with some shimmers degrades the whole experience.

Thanks.  The Nvidia Control panel settings you mention...are those your settings under the 'Global' profile or a specific P3D.exe profile

Its the 'Global' profile...if you like you can test setting them on the specific P3D.exe instead (I'm not home right now to test).

For my setup of 1920x1080, I found no advantage setting DSR 2x or higher, vs, simply setting NI SGSS matching my internal  P3D MSAA setting. My current setting of MSAA 4x internal and 4xSGSS in NI renders the best visual to performance cost ratio.

the best I've seen P3D on my system since i got V2.  However, my frame rates have tanked somewhat

That's the catch!  :excl: :mellow:

 

Running the fixed fps in P3D (and FSX) is not a simple frame rate limit, like the setting in NI or an external limiter. Fixed fps in-sim invokes D3D look ahead frames. Look ahead frames, or pre-rendering, adds an initial cost to the maximum frame rate. This is often mistaken for a bug, so although we may see 60fps with Unlimited setting, we find we can only lock at 30 to 40 - because of the cost of look ahead pre-rendering. We can set the look ahead frames to 1 in CP or NI to reduce it (default 3), but is still not exactly the same as Unlimited. With pre-rendering some other work is done in our favour, so that the GPU can apply new detail in a smoother fashion. We should be able to get a smoother overall result by setting the in-sim fixed fps setting, (and matching that with NI fps limit if the setting allows), but we lose out on high fps. :excl: :mellow:

I have only set performance to max (instead of adaptive) in the NI and thats it. No other tweaks at all. (is aero a tweak B) ?)

 

I will do a video in the NGX like the one in the 777 in KLAX. I was just amazed again last night in both KLAX and MMMX 

 

This is really a dream come true .These last weeks have been the best in simulation inviroment

I seems that there is just as much hacking and fumbling about with P3D as there was with FSX to achieve a certain result - with no guaranteed result at all.     Appreciative of all advice though.  I'd be at a loss otherwise.
