Patrice,
My suggestion is as follows.
I'm hoping to get the Radeon usage code working today. When done, I'll send you the sources and we can release this build as ObjReader v2.5 Stable. We will be keeping it available for users even when working towards ObjReaderFBO w/ post-processing and other capabilities and we will be using it as a reference for our own progress.
When ObjReaderFBO is ready as v3.0, we will still be offering v2.5 for users with simpler hardware and undemanding needs of viewing .OBJ models in a decent viewer. At the same rime, my own goal is to keep on introducing more and more editorial features like lighting, cameras, simple animations, pre-/post-processing effects, etc. Possibly adding an own binary file format to keep these candies in the model file itself as .MAX, .LWS, .C4D files do, and also to make file sizes significantly smaller and faster to load etc. etc. etc........
I will also send you my Fraps installer. It's free to use and it works in 64 bits like a charm. It's still a 32-bit binary itself but it installs a 64-bit detour on the 64-bit OpenGL and/or DirectX drivers to be able to work with both bitnesses simultaneously.
