SOLVED Moire effects

I am encountering the following Moire effects on Lime Rock Park 3.05:

I have already tried different graphics settings from Very Low to Ultra to no avail, also two technically different computers of mine show the same results

Lime Rock Park Youtube videos I watched were fine, no Moire at all

Can anyone shed some light on this mess?

Your resolution looks really low, you need some kind of anti aliasing to minimize that effect i think ... or use a higher resolution.
 
As I said, I tested all graphics "resolutions" from Very Low to Ultra, where Ultra has every single setting maxed-out

None of these had discernible impact on the Moire effects
 
To some extent this effect with guardrails is unavoidable, low resolution , low or no aliasing , make it worse. Maybe even anisotropic filtering can get involved.

It looks like you talk about quality and not pure resolution. By resolution we mean the number of pixels your screen displays ...

On a 2k or 4k you should have at least a grid of 1440 pixels in height or more. Your screenshot shows probably only 400 pixels in height.

You're on an Ultrawide, or Multi screen ? Are you in 7600 x 2600 or else ?
 
@DanRZ : Sorry for the confusion. My screen resolution is 1920 x 1080, the screenshot only a relevant part of it

My reply #5 was related to #4, which appeared to refer to the graphics settings

Also, I picked Lime Rock Park, because the effects are most obvious there. On Nordschleife, with similar guardrails, it is less pronounced

Anyway, I had a similar problem with American Truck Simulator. There, I could adjust a parameter called "scaling" (whatever that means) in a configuration file, which significantly, if not completely reduced the Moire effects

I was hoping that something similar is possible in rFactor 2 as well
 
Thanks, i was confused with that screenshot.
If it's on long distances, try to modify the FXAA parameter, it changes the way distant pixel are anti-aliased ... Go 8X, 16X, modern cards can handle that.

I never mentioned graphics settings, just "resolution". Anyway, it's fine.

In the graphics settings, change the "Texture filter" setting to any of the Anisotropic options. The higher the better but also slower.

This is in addition to setting FSAA to something other than off. FXAA is optional.

But for texture filtering issues over large distances, "Texture filter" anisotropic is the solution.

Almost all graphics profiles set anisotropic texture filtering. Is your GPU driver disabling anisotropic filtering?
 
Thanks to both of you, FSAA did it

For people, who run into the same problem:

FSAA can be set to None, MSAA 2x, MSAA 4x, MSAA 8x
where for None to MSAA 4x, the Moire effects go from worst to least, and for MSAA 8x they are gone

In conjunction with Texture Filter x4 anisotropic, I have now a Moire-free, fluid picture:

It's easier to diagnose issues with full screenshots. We can zoom in anyway. I use MSAA x4 and never noticed this issue but maybe it's dependent on other settings. Good that it's fixed, it looks much better.
