It’s a question of whether we tell the driver to do it (via an OpenGL call) or you do (via a control panel). Either way the driver is doing the FSAA and AA.

The driver can take short cuts in the way it does FSAA or AA, often based on a series of heuristics from OpenGL API calls (e.g. guessing what we want) or from special control panel settings. So if it’s faster, it’s probably lower quality, but that may not matter…the fps may be more important.

So…I’d say if the driver setting looks good to you and is faster, use it!

I guess it gives the same results?

Also, I read that forcing AA or AF via video card drivers rather than activating it inside an application can give better performance. Don’t know if it’s true though.

Thanks a lot for this much needed option. 16x is indeed overkill when even 2x can give very satisfying results on a modest hardware.
