This week moguri commited in Trunk revision 37521 a patch in BGE to add Anisotropic Filter. It´s a great improvement for us :evilgrin:
To use this take a look in Preferences/System
Committing patch #25676 Anisotropic filtering in viewport and BGE by me.
This patch adds anisotropic filtering of textures in the viewport and the BGE. The quality of the filtering is adjustable in the user preferences under System. For more information on anisotropic filtering:
One current limitation of this setup (having the option a user preference) is it makes runtimes more troublesome. Runtimes don’t have user preferences set, so for now the blender player defaults to 2x AF. Options will be added later to change this value (probably a command line option).
Thanks Moguri! :evilgrin:
