Dx11, noise in details in 3d models

Is there a way to fix this shimmer (like on building’s wall)?

It’s smooths on it’s own on close up,

but I need models to be smaller and there is no way to simplify them.

If the details are geometry it might be a problem with z-fighting(, which I’d fix by increasing the distance between the geometry, changing the depth bias or decreasing the distance between the NEAR and FAR values of the camera.

If it’s a texture, I’d increase the mipmap level.

changing near and far of the camera really helped! Thanks a lot! ♡
