The issue is actually that "Anisotropic Filtering" is bugged with patch 1.9, which means that any texture at a skewed angle, and even at a slight distance will be blurred.
I've both heard it, and seen it. (And I do know how it looks when it's OFF.)
I confirm the above, it was mentioned in the known issues of Patch 1.9, if running on DX9. Tested it yesterday, compared screenshots and yes, it's true: no anisotropic filtering, you have to force it via the GPU drivers.
