Is there any faster methods for improving texture quality on oblique angles than using anisotropic texture filter?
In my previous question i asked if it takes more memory than normal mip mapped textures, but apparently it doesnt, so i am hoping this could be optimized.
So is there any way to optimize the rendering speed ?
No. The alternatives such as supersampling are significantly slower. Your best bet on OpenGL is using the anisotropic filter.
