Hi. I'm not 'new' to opengl nor programming but I've only recently started work on independent projects outside of messing around in textbooks with fixed pipeline and programmable pipeline projects, glsl, etc. Basically the basics are basic to me ;)
However, I've only started experimenting with the texture filter modes. On a heightmap terrain I had the mag filter as GL_LINEAR and the min filter set as the same, and my app was crushingly slow. Now I set the min filter as GL_NEAREST_MIPMAP_LINEAR and the performance shot through the roof!
I was under the false assumption that using mipmaps would slow things down somewhat. So what gives?
