Okay, I was recently directed to a OS X hint that shows how to use OpenGL profiler to add anti-aliasing settings to programs, this is a nice tip but it's a bit annoying to have to re-do it and always go through OpenGL Profiler.

What I'm wondering therefore is if attaching a custom OpenGL profile to a program can be done using a script or such that will attach it when the program launches, or which you launch instead (ie double-click the script to attach a profile then launch the app)?

I'm relatively inexperienced with all things OpenGL so go easy please

AFAIK, you can't do this yourself, since it's a system-level thing. However, if you have an ATI card, you can use ATI displays to do this for you.

Why don't you just do it programmatically by creating the right OpenGL context?

He's talking about adding FSAA to commercial games that don't expose a setting for it...
