I am trying to dynamically figure out if a requested texture format will be honored or translated into something else. I attempted this with proxy targets, but that does not seem to work. I simply get back whatever I put in. My backup plan is to generate a table for each of our know cards. I am currently referencing this site:
http://download.nvidia.com/developer/OpenGL_Texture_Formats/nv_ogl_texture_formats.pdf
This is the type of data I am looking for. However, it does not have my graphics family referenced in this document (GeForce 7600).
So, does anybody know where I can find info for the GeForce 7600 (supported formats)?
Does anybody have a dynamic way of determining explicit format support?
