Question Nvidia Profile Inspector/Control Panel Q: Does D3D/Direct X support Forced AA options? Or only OpenGL?


May 30, 2016

Looking for explanation/clarification. I've tried searching but most stuff is from 2004/5 and I don't know if things (drivers, architectures, etc.) have changed since then. Also, sli aa google searches are giving vague results.

I've got SLI AA 8x enabled in the nvidia control panel and see its indicators like so:

However I don't see this indicator in any games I play, nor any performance impact. When I see anything it's just the usual Green Bar, or nothing. Which makes me think it isn't using the SLI 8x AA mode I've chosen but whatever the game engine says or nothing at all. I've tried "regular" (non SLI) antialiasing at 4x and 4x supersampling. Doesn't seem to take?

Ignoring the SLI for a moment, curious what does the "Override application setting" actually do? How can we know if it is working? Are there scenarios where it doesn't work? What do I have to do in nvidia Control Panel or Profile Inspector to actually get the Anti-aliasing settings I've chosen? Does the game's settings for things like Ansiotropic, Ambient Occlusion, and AA always take precedence despite what's being advertised? Do I have to change some settings or disable things in the game vs. the Control Panel or NPI?

Any input would be great, thanks!
