What you need to do, if you have a graphics card that has a configuration program (ATI cards have Catalyst Control Center, NVidia cards have something similar), you need to open it up, find "Anisotropic Filtering" and set it to at least 4x, preferably 8x, or 16x if you think your performance won't suffer.
Why?
Well, here's before 8x Anisotropic Filtering (Remember, you can open the pictures to see them bigger):
And here's after:
Doesn't that ground texture look fantastic now? It's no longer blurry just 4 feet from the camera, and it even looks better close to the camera. What Anisotropic Filtering does is it basically renders the textures in a different way so that they look better when the camera is at different angles.
Here are some more examples of before and after anisotropic filtering:
Check out the windows. The ground in the park works, too.
And the water, too. It looks better.
And in this one, the ground texture is better again- but check out the dining tables. Even they look better now.
It also very subtly makes beards a bit more detailed (very, very subtly, though). Same with freckles.
