sorry, it’s a bit out of my deeper knowledge.
if you try searching like this unreal make materials look good from far at DuckDuckGo
i found this
How to stop Textures from looking bad from afar? - #2 by ClockworkOcean
i was going to suggest is to handle the change in the material, based on distance. which is what is said in that link.
for example your material seems to have bump mapping or wpo in it. i would lerp the wpo so it’s basically disabled at certain distance. so that the material is flat.
this makes sense since your problem is very akin to lod (not mesh lod but material lod)
you can also play around with ddx/ddy (search for prismaticadev if you wanna know what is it).
ddx/y will help you fix the issue with view angle.
you can try changing your AA method (though i’d say save that as last resort, since it’s players will really want to choose their favorite AA methad).
also ensure it’s not an issue with the resolution percentage (which lowers (and it’s good that it lowers) when you lower the performance profile).
