Ok. I have a little more information for you guys. Just to recap the situation: When I run using Bilinear, I get 30 Hz. When I run using Trilinear, I get 60Hz.
During my investigation, I noticed that their are actually 2 bilinear modes: LINEAR and LINEAR_MIPMAP_NEAREST. LINEAR does not include any mipmaps, whereas LINEAR_MIPMAP_NEAREST will include mipmaps. As a test, I modified my texture attribute visitor to replace LINEAR by LINEAR_MIPMAP_NEAREST. Now, the performance is similar to using Trilinear. It seems that the graphics card does not like using Bilinear textures without the mipmaps. Does anyone know why?
