Hi, I would just like to know, are AMD's drivers backwards compatible all the way to 1.x?
I know that nVidia says they will always offer the compatibility bit.

According to the last sentence of page 3 of this paper (http://developer.amd.com/gpu_assets/GL3_WhitePaper.pdf), they have no intention of removing Pre-OpenGL 3 features.

Technically, all that says is that they're still going to support GL 2.1. That's different from exposing the compatibility profile.

However, to answer V-man's question, AMD does provides compatibility profiles for OpenGL 3.2 and above.
