Most games use AnisotropicFiltering = 4/8/16. It sharpens your textures under different Angle View.
Anisotropy makes a performance draw back about 10-40 fps, but the result looks much better.</p></div>

<div class="paragraph"><p>JME has DEFAULT AnisotropicFiltering = 0. So, if you make a game for Windows/Linux/Mac.. you need to set the Anisotropic Filtering more than 0.</p></div>
