2-Way SLI AA?

[chaikovski2002]

Im not sure how this works, but I have 2 way SLI atm, and what is the best way to go about AA in CP settings under game profiles? When running SLI supported game should i have 8xAA in CP or SLI 8XAA in CP? Is there a big difference in terms of visual quality? Is there a big performance hit with SLI AA versus regular AA?

I ran SLI for almost a year and never saw an "SLI AA" option but I've read a lot of talk about it.

My personal rule of thumb is to not use control panel AA options. I figure if a game is designed to have AA, it will have the option in game. It's not like developers don't know about it, so if it's not there, it's likely on purpose. One time I had to use a control panel option to Force Off V-sync in Fallout 3 because disabling it in the options doesn't actually work. I've also forced on a few options in Dead Space to fix issues I were having. Otherwise, I use in-game options only.

I just ran a few games and 8xAA in a regular SLI mode still offers superior performance by quite a stretch, about ~30-40 fps difference b/w 8xAA and SLI 8XAA, so it seems best make use of the 8xAA mode under normal SLI operation.

If you're talking about running 8xAA with SLI off vs. 8xAA with SLI on, well the latter will be faster since you're using two cards to do the work. What specific graphics cards are you using btw?
