Noisy textures everywhere!
polycounter lvl 9
It seems that lately, games are using very noisy textures to supplement actual detail. I don't know if this is created by multiplying a noisy occlusion map over everything and tiling it however many times as necessary but I noticed a lot of noise in Last of Us (a game I really enjoyed) and I just finished Assassin's Creed Black Flag (a game I medium enjoyed). Both games seem to "suffer" from this effect and as I try to reverse engineer it, I'm also trying to figure out how to combat it... but I'm hardly a tech artist.
Is it possible to remove the noise as the camera gets further away? Something like an LOD without the noisy occlusion? Just something to add a little more atmospheric perspective so the noise doesn't carry out infinitely. Or perhaps just give the map smooth and noisy areas for a little more inconsistency? But I'm sure that's been tried before.

I compiled several videos of the noise in various materials (foliage, dirt, especially stone) but the last clip shows a stone fort that looks so much better than all the other materials. They clearly have that capability of non-ugly materials... but Assassin's Creed was just plagued with noise. And I don't feel like this is a style exclusive to Assassin's Creed or Last of Us.
BEHOLD THE NOISE.

but yeah, maybe decent mipping would actually help with the overall noisiness. I'd just be careful of putting too much noise in the diffuse maps.
That is correct, heres a .gif I made showcasing this. It goes from a value of 3.0 which is the original value, then 2.0, 1.0 and off (but this also turns off other post processing stuff). https://dl.dropboxusercontent.com/u/9876544/witcher2sharpen.gif
A comparison between 3.0 and off.
