Fixed P3Dv4.1 Shimmering even with MSAA in use

Recommended Posts

In my eyes,  this was a break through.  Myself,  like many others,  are forced to use MSAA with PMDG dynamic lights to get dramatically better performance.  This indeed does the trick but you will sacrifice the dreaded distant shimmers.  I'm using ORBX vector, base etc. with their night lighting and while it looks fantastic,  those distant shimmers just bummed me out.  So,  I went ahead and started experimenting with NVidia inspector and was able to cure my problem.  

So here we go,  my in SIM settings have FXAA off with MSAA set to 4 while using Dynamic lighting set to "on".

Inside inspector,  I have the following....

Antialiasing - Mode = Enhance the application setting

Antialiasing - Setting = 4xS [Combined: 1x2 SS + 2x MS (D3D only)]

Antialiasing - Transparency Supersampling = 4x Sparse Grid Supersampling

Thats it.  These settings helped me out without sacrificing frames and performance.  Try and Fly!

Thank you, Tony. I will try this.

Question: Do you or anyone knows a way to reduce that strong white or metallic shine on airplanes?  I use PTA, and though it adds better colors, it also makes the a/c 'white' colors shine way too bright. Not sure if this is HDR related, or maybe there's an NI settings to reduce ?

I assume you're referring to the Bloom setting, which can be moderated by either the HDR lighting settings within P3D or via PTA; NI has little to do with it in my experience.

Thank you for the info, sorry this is most likely a very basic/newbie question (I should know better), but is it a one time setting while you run NV Inspector (once I hit apply)? Do I need to run NVI all the time to benefit from these settings? 

Thank you!

John.

Once you hit apply it will remain. It will only change, (if) you make any changes and  click apply again.

What video card & what drivers. Thanks.

SGSS destroys frames more than SSAA does.  It does a good job but in heavy clouds you will notice a large performance hit.

This never worked in P3D, since v2 was it? What changed now, because we are still on DX11?

In the end, it's SGSS that's doing the job, not 4xS (which isn't working).

Have you tried this with the Grey and Rainy weather theme?

Yes,   No issues.   Of course,  im using a 1080Ti with Unlimited Frames w/ Vsync and using 30Hz monitor refresh rate which also gives me a smooth ride.

It’s only the SGSS that helps with the shimmering. It has always been like that. 

And it will cost you a lot of fps with many clouds , multiple cloud layers . Add rain and you will not be happy....

We've got VR and that bridge in St Louis though 🤗

Well.... that's always a nice ace to have up your sleeve.  :)

But as said above I think you will see the same results if you just leave:
Antialiasing - Mode =
Antialiasing - Setting =
both to Application Controlled.

Unfortunately, I can concur that this is the exact issue that I encounter when attempting to use 4 X SGSS to eliminate shimmering. 

This being the case, are there any other adjustments that can be made to reduce shimmering whilst at the same time, not taking a substantial FPS hit in heavy cloud - which is something that we have a lot of here in the UK !

I have flown for a while with these settings, and have been quite happy with it:

Antialiasing Mode - Enhance the application setting

Antialiasing Setting - Application controlled

Antialiasing - Transparency Supersampling - 4x Supersampling

These are though with P3Dv3. Some slight shimmering sometimes stlll but nothing so bad, and the the FPS are quite satisfying (most of the time)
