Should you use Nvidia inspector

Recommended Posts

Hey all, 

 

Been reading around quite abit and it seems that there is a mix vote. Some saying to use Nvidea inspector and others saying its best to not.

 

Whats everyones opinions? And settings ?

Using Just P3D out of the box Jack. Not one tweak. Getting great performance. Have removed Nvidia Insp the same time I deleted FSX.

Of course, it depends on your system. I am only running a GTX 580 1.5 GB Vram, and I get very little shimmering, and no OOM's with the NGX and T7.

 

I have most of the eye candy enabled, so very pleased. Just test without NI and see what happens.

Good question.  When it comes to this issue, there are only a handful of people actually  know what they are talking about, but for the most part it does seem fairly hit and miss.  The neat recipe which existed for FSX graphics' nirvana' doesn't seem to apply here.  I've chosen not to use NI, and although my graphics are not bad, they are certainly a far cry from what I was used to with FSX.  I'm kind of at a loss myself because I honestly don't know enough about what the different graphics settings are supposed to do

 

I look forward to a P3D specifc profile backed by Nvidia

I have to agree with that. It took a wee while to get the sliders in the correct position till I was happy, all the time avoiding applying any tweaks, or turning to NVI to make those fine adjustments.

I was also concerned about using my current video card, as it is getting on a bit, 3 years is old in the computer world. But, I have been pleasantly surprised, in fact gob smacked to be honest, I have never known it to be so smooth. Not even a micro stutter.

The only thing I have turned off is HDR, and Terrain shadows. Cloud shadows on, using ASN.Below is a fsuipc log of my last flight from FSDT to TJSJ

 

I had 1.3 GB VAS remaining on arrival at TJSJ in the NGX,  quiet amazing when you consider no tweaking on a 3 year old system.

It's not "hit and miss" at all. The confusion arises because P3D is DX11 and that is more like FSX DX10 than FSX DX9. Using NI like we did with FSX DX9 does not work, because DX10 and DX11 graphics are produced in a slightly different way internally than DX9 graphics. The old NI FSX DX9 settings won't work, but there is just as neat a recipe for P3D (and FSX DX10) as there is for FSX DX9, and just the same, you'll need to use NI for the best visual settings. Currently there are some issues with supersampling in P3D/NVidia, for the best results read more about using NI for DX9, DX10, and DX11 here

Thanks for the link Steve. Will look into that.

Hey Julian.

It covers settings that are generally repeatable across all modern PC systems with nvidia cards.

Regards Steve.

I started a similar topic a couple of weeks back thinking I might gain more Performance but it was suggested to me to use PD3 out of the box no tweaks. Im happy with my choice.

 

In saying that, some folks swear by it. You gotta know your stuff if your gonna tweak.

Some aspects of DX10 and DX11 graphics actually require the use of NI to set up the GPU, to improve the visual quality of some objects. If we have an aircraft loaded that looks poorly anti-aliased, or some instruments that look extra pixel-y, then we need to use SGSSAA as described in the link, set with NI. Improvements in visual quality essentially mean decreases in performance, and that's all part of finding a personally satisfactory setup.

Not many options for P3D Erich, so not a big deal really. All the best, Steve.

One question from me....

 

I have noticed, what I can only describe as colour 'banding'.  When i look at the blue sky - or whatever colour the sky is, I notice distinct and hard banding of the shades of that colour (dark blue to light blue).  There was a setting within NI for FSX which which would eliminate this and make the shades of colour more diffuse and soft with no distinction of a 'border' as such.   It is also very evident at night.  Last night I noticed it when I had the 777 parked at OMDB under the floodlights.  The light scattering on the white fuselage had distinct bands of soft orange light and the NAV lights projected a somewhat hard edged light on the apron instead of a more scattered/diffuse light.

 

Is there any setting which I could use to eliminate this?  I hope I've expressed myself well enough for you to know what I'm on about.

Yes that's due to a lack of texture filtering, set Anisotropic in P3D x4,x8,x16.

I believe my Anisotropic is already set at x16.  I will try the NI settings you posted earlier and see if that makes any difference.

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
