PBR - Do we need SGSS (NVI) again?

Recommended Posts

Posted (edited)

I've realized that PMDGs 747 a/c with new PBR textures show antialiasing issues with horizontal lines. According to some posts in the new PMDG forum it seems that SparseGridSuperSampling (Nvidia Inspector) does help indeed. I have now 4xSGSS set in NVI and PBR textures look much better now. Not sure if this also applies to PBR at airport scenery.

For sure SGSS in NVI will help. But it will also greatly hamper performance in cloudy conditions when using any weather cloud addon such as ActiveSky and/or REX Sky Force. At least my 1080Ti does not like 4xSGSS in such situations...

I must admit that I noticed some kind of "shimmering" effect to the PBR textures on my Quality Wings 787-8 when I rotated the spot view around the plane last night, but I did not think too much about it at the time. I will need to make a closer inspection to see if this is an issue or not. For the record, this was with dynamic lighting and dynamic reflections disabled. My P3D settings are 4xSSAA and 16x AF (and FXAA disabled).

Somebody in the QW forums mentioned that after he went through all textures of a repaint with the dxtBMP tool, ticking the checkbox "add mipmaps when saving" and saving the textures as DXT5 .dds completely resolved the jaggies with PBR.

I did not yet have time to check if this really works. If yes, it would be a "workaround" that should work equally good also for the affected PMDG repaints and I would wonder, why none of the devs found this workaround themselves....

I have the same issue with the jaggies with the new PBR and couldn’t get them to go away no matter what sim AA setting. Read a post by PMDG that it’s a p3d issue and is going to be corrected in 4.5.

Hello. I am still getting jaggies with the BA CIVX livery having updated P3D to 4.5.

Don't know how to roll back until LM sort it out.

Some developers allow you to disable PBR. Unfortunately, PMDG do not.

Personally even with the AA issues with PBR, it looks so much better than non-PBR that I'm willing to deal with some aliasing for now.
