Can someone confirm whether or not that ATI allows the use of NON power of 2 texture sizes? There web site does return any results when searched.
Or perhaps the driver resizes first?

Texture sizes must be POW2 - however, if you use gluBuild2dMipMaps then they will be rescaled to POW2 anyway.
NVIDIA cards can use the GL_NV_texture_rectangle extension.

Don’t know if ATI has something equivalent… Some ATI people (or perhaps Humus ?) may be able to answer that.

I was told for a fact that ATI supports non power of 2 textures. I’m sure it’s nonesense, but there you go!

They DO support Non Pow 2 textures, but only in D3D. I was told that there would be an extension to solve this, however I haven’t heard anything since (this was quite awhile ago).
