Fixed P3Dv4.1 Shimmering even with MSAA in use

Recommended Posts

I find that a p3d 8xSSAA gives me impressive visuals with almost no shimmer, but at certain payware airports it causes fps problems with my gtx 970. I'm sticking with 4xSSAA for now since visuals & performance are very good.

As for nvidia Inspector, it doesn't work for me as it did in FSX. I have the same issue I had with XPlane with HFR enabled.

I'd be interested to know if upgrading my GTX 970 to a 1080 would help improve performance with 8xSSAA enabled assuming all my other P3D settings remain the same?

Good luck with 8xSSAA using something like the PMDG 737-800 which forces you to use DL if you want to see where you are going at night....most cards will crumble.

8xSSAA at what resolution and refresh rate?  You might be able to make that work at 1080p and 30Hz, but even a pair of overclocked 1080Ti GPUs won't pull that off at 4K.

Here's what I'm using:

  • FXAA - Off
  • 4xMSAA
  • Anisotropic 8x
  • 2560x1440 Resolution

As far as the advice in this post:

  • Antialiasing mode - Enhance Application setting
  • Antialiasing - Transparency Supersampling = 4x Sparse Grid Supersampling

I tried and removed the:

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

This was giving me some strange lighting effects in the VC.

All this was tried on my maximum environment: Orbx NCa, Flightbeam KSFO using the FSL A320X Airbus with fog and cumulus clouds.

I haven't been tweaking much, as I'm really happy with things in P3D, but I saw this post and thought I'd try them. I was seeing some texture flashing when looking towards the terminal.

 

I think the conventional wisdom with these settings in DX9/10 is that the MSAA and the SGSS multipliers must match...so 4xS was never a good match for 4xSGSS, but rather 8xS (2x2 SS + 4x MS).

That said, I am not confident that the 4xS/8xS settings have any effect in DX11.  Could be that the 4xS in the OP's config is a placebo, with the real effect coming from the SGSS.

Thanks for the input. I forgot to mention, 1080p and 30Hz. I don't have a 4k monitor. I'm waiting for volta.

I can't make NVI AA settings work, I've tried several combinations already. I have a 4k screen powered by a 1080TI FTW3 overclocked and it's just not sufficient even on 4xMSAA (set inside P3D v4.2), it will easily hit 100% load especially with some cloud layers.

During the FSX times I remember to have to set a special flag or something for it to work, now I'm stuck with the same kind of problem within P3D. Is there something necessary to change?

Thanks.

I am running a 4K TV @ 4096x2160 and still had some annoying shimmering, especially the power tower pylon textures in Orbx PNW.

I was finally able to fix most of it by using 8XMSAA in Prepar3d and with  Inspector using Anti-alias mode  set to "enhanced"and Anti-alias - Transparent super-sampling set to "8X Supersampling". 

I also have Texture filtering - Quality set to "High Quality" and Power management mode set to "Prefer Maximum performance". 

This worked for me in both v3 and v4 of Prepar3d.

This cleared up about 98% of the shimming and no performance hit like SGSS.

What card are you using??

Looks like it works in my case too - 1080 GTX also with latest drivers.

8xMSAA in P3Dv4.2 + Enhance + 8x transparency supersampling in NI = much less shimmering.

Thanks for advice!

New P3Dv4 user here - I was having issues with scenery shimmer and jagged lines on the aircraft external model. The settings posted above cleared the external model jagged lines and cleared around 90% of shimmer. Considering AA seems to be an issue with P3Dv4 I'm very happy with the results.

I'm using 2 x supersampling so not be destroyed in cloud.

Are you running this with dynamic lighting on? Have you tried these settings at night with dynamic lights visible? I'm skeptical this setting *actually* works without tanking your FPS.

Takes about 10 FPS off of mine (GTX 1080), though it does seem to balance out SOME distant shimmering but leaves jagged textures on my aircraft fuselage.  I suppose it's a balance of half jagged edges, half shimmering.  DL on.

10 FPS out of how much? 8x MSAA alone for me (1080TI FTW3) is hard enough depending on the aircraft and mainly on the clouds setup, so I end up using 4x MSAA. I think shimmering bothers me even more than aliasing.

Thank you my friend!

Those settings completely solved every shimmering issue here!! 🙂

There should have been an initial caveat to this thread along the lines of "If you have a 1080ti gpu here is a fix for shimmering".  I would love to get rid of the very excessive shimmering in P3D compared with FSX but at 1400 Australian dollars for a 1080ti my 980ti bought just 14 months ago is going to have to do me for some time to come!

Likewise with 4k TVs/Monitors.( Mine is still 1080p).

What settings? It's an old post, things evolved massively to me, nowadays I can use 8xMSAA without noticeable performance loss and the image quality is much better. There's mostly no aliasing and no irritating shimmering like before. My screen is 4k but it doesn't help really, like some might suppose, because it's huge, it's a 55 incher.

Ha, okay sorry Wanthur, I accidentally quoted you instead of FlightSimDim

So once more thank you indeed, this time to you FlightSimDim 😉
