P3D3 - some basic nVidia advice?

Recommended Posts

Hi, sorry if this has been covered elsewhere but I've just bought P3D3, and before I run it, I'm just looking for some basic advice regarding AA/AF, etc settings for nVidia, with P3D3.

 

1. Should I use N.Inspector (works great for FSX), or stick with the standard Nvidia Control Panel?

 

2. Should I "override" P3D3 settings on the control panel, or use the application settings?

 

3. Any recommended settings for AA/AF/Vsync ?  I have a a GTX670 2GB, and I use TrackIR so need Vsync working.

 

Many thanks in advance,

For what I have used of P3D V3 so far, I haven't found a need yet to tweak any settings outside of the core program.  I'm not sure though if nVidia Inspector reads P3D V3 yet (I could and can be wrong on this).  If you want to take a cautious approach, a wise man once said that in order to get your sim running at peak performance as well as achieving stability, only apply one tweak at a time and each time, run the sim.  Use a complex aircraft each time so you can stress the sim and measure performance and stability.  By doing so, you effectively create a limit that you know you don't want to go over.  With all of the recent comments and reviews of P3D V3, it functions a lot better than it's previous version so you may find that you can bump up your settings a little more than before, but again use caution as everyone has a different computer and setup.

Thanks Jim.   Would you advise setting the nVidia Control Panel to use the application (P3D3) settings for AA/AF, or is it still prudent to override them, as per FSX ?

Probably the best thing to do is change your settings within P3D V3 first and see how the performance fairs.  Don't put too much stock in FPS as you really want to achieve a smooth flight.  Again, with P3D V3, they have changed the way scenery is loaded, which helps a lot with VAS and FPS.  I have my sim set at 30fps and I get very smooth flights that are stable.  As for my graphics settings in P3D V3, they are in the 'high' range, but I don't have all of the sliders maxed.  That can be overkill. :)

If you need SGSSAA, unless you have a 4k monitor and high pixeldensity, the use of NI is an absolute must! - still in P3D v3.

 

And no no no no.... it doesn't destroy anything! not in P3D, not in your PC not in your Mon, it doesn't even darken the sun ;-))... nothing... and- you can easily switch it back (but you know that from fsx...).

 

All you need is apply 4*SGSSAA by NI - nothing else needed in NI.

 

In P3D set 4*MSAA to match.

Good post from the OP and its exactly what I'm after as well. I haven't had much time to completely throw myself into V3 yet - I'm hoping to have a whole weekend to do that this week.

 

I'm still stuck at the default airport on the runway in Virginia, trying to get controllers to work properly and playing around with graphics settings. Having taxiied around the airport, I can't say that my performance is amazing, it's a bit stuttery with settings at about 75% of max. I haven't yet applied an AM and I'm not sure if I have optimal graphics settings myself. I have some graphics anomalies, for example if I look at the sun, I see a pink transparent square shape infront of the sun - not sure what that's about. ( AF set at 16x). I have a 970STX Stix 4GB card and my machine isn't a slouch. AA isn't bad, but it's not great. I've not set anything in Nvidia Control Panel as I don't have it installed.

 

If anyone with pleasing graphics can suggest, or post screenshots of their settings that would be appreciated.

Needs: that is a loaded word.  There is a long-standing tradition in the flight sim community based on "for and against" tweaks.  Many new people come here and pour over the countless posts from people using the word 'need' and the new people automatically think they need to use the same thing, then later on they come back saying their sim is broken.  Again, I cannot stress enough that when it comes to adjusting your settings inside and outside of a simulator, that you take it step by step.  Patience wins every time.

 

Now, I am not saying that any other advice you get is wrong, but be aware that everyone's system is different and their, dare I say, 'needs' are different.  You have to assess what you really want out of your sim.  If you want eye candy, tweak away. If you want performance and stability, take it slow, find necessary adjustments and test, test, test.  I admit I learned the hard way in the past by automatically applying tweaks in my cfg file and then subsequently, opening NI and making changes there without assessing the current state of my sim.  Complex aircraft, scenery and other add-ons are game changers.  Just when you think everything is just the way you want it and then you install other add-ons, you may or may not find that all the work you did needs to be revised.

Thanks guys, some great pointers.

 

I also found this stellar thread, which culminated in Gareth's post here:- 

 

http://www.avsim.com/topic/459884-optimum-nvidia-cp-settings-p3d-24/?p=3157552

 

I've tried these settings off the bat, and getting fantastic results (early days!)

Look at post #37, from Rob.  Also consider that this post was done in January of this year...older version of P3D.

 

You never mentioned what you have or will install for aircraft, scenery, traffic, weather.  All of that can make a difference.

Hi Jim, Yes appreciate that thread is from Jan of this year - but the essential advice I picked up from it was to set all values in Nvidia Inspector to "application controlled" except the Supersampling Transparency, which I set to 2 x Sparse Grid.   I then set Rob's recommended settings in P3Dv3, and although the thread was relating to P3D 2.5, my P3Dv3 is looking and performing fantastically.

 

for add-ons at present I'm just using Orbx FTX Global, OpenLC NA Canada, OpenLC EU, FTX England and FTX Pacific North West (all with dedicated V3 installers).    For aircraft, at present I'm just using a couple of pretty simple GA aircraft from Alabeo (read PA38 and Sportcruiser) - all working great.

 

Next step will be to buy the A2A Cherokee for P3Dv3 (I have the FSX version), in order to be able to use the F1 GTN750 for P3D that I purchased last evening.

 

Thanks for the help folks.  Loving P3Dv3.

For basic decent AA we still need the Transparency Sparse Grid Supersampling setting in NI.

 

Set P3D to 4xMSAA, then make a default profile with NVidia Control Panel (CP) by selecting the P3D profile and press Restore and Apply buttons. Now create a new profile by making any change you like in the CP window, say set 4xTSSAA, Apply. Close the CP.

 

Take care to start with a fresh profile especially after driver updates.

 

Run NVidia inspector (NI). Choose the P3D profile, Leave all AA settings at default apart from: Set "Antialiasing - Transparency Supersampling" = "4x Sparse Grid Supersampling" matching the 4xMSAA set in P3D. Set "Antialiasing - Mode" = "Override any application setting". In my tests here override is the faster and smoother performance by maybe as much as 5%.

Great, thanks SteveW, I'll ensure that the SGSS and MSAA both match up, at 4x, and I'll give "override" a twirl.   Cheers.

You're welcome! Only the transparency sparse grid settings make any difference in the AA section and must be set to the MSAA setting as you say. Use the sim setting to change the Aniso mode higher values improve the look of reflective and wet surfaces into the distance with higher values. Other than that, that's all we can do to improve AA.

Hey Rich! Thanks for helping me out last week!

 

Those checking out P3D AA are best advised to try just MSAA with the default NVidia profile created as I demonstrated above, before adding the sparse grid setting. This is supersampling and costly in terms of render time because it's like rendering twice as big an image to produce the antialiasing. Also with big res screens may not need SGSSAA.

This is exactly what I stumbled into about a week ago. Locked at 30 fps, I have found results wonderfully enjoyable. Average frames are 29.9

Your little section on what and how to set made a world of difference on my system. Finally the AA in P3Dv3 is closing in on FSX.

Thanks Steve, it works like a charm!

 

The only problem I have with MSAA in P3D3 is with bad weather/snow. With default ASN options, flying over Greenland (so nothing really happening outside), I'm experiencing frame rates in the twenties with snow and overcast, unless I turn MSAA off. This is with or without the changes in NI (with the changes it gets slightly better, in fact).

 

I have a good system, GPU is a 970, processor i7 4790, and usually fly with frame rates above 60 inside the plane and well above 100 outside.

 

I was using PrecipitFX (default snow is awful...). It gets better without it, but not much: still around 30.

 

Everything else is default P3D3 (clouds, etc.). Cloud coverage at medium, but I can crank it up without loosing much. The real "game changer" is turning MSAA off: FPS goes from around 25 to above 70 again!

 

Am I missing something?
