Anti-Aliasing stopped working all of a sudden

[Biosolids37]

Hi, for no apparent reason, my Dolphin stopped applying AA. Is there any way to make it work again ?
I've tryed forcing it in the amd control panel but no luck. Im using latest build, and my video card is an ATI 7950 3gb.

Edit: Apparently it only happens with this one game: Haunted mansion. Weird.
Edit2: The AA seem to work if i open the graphics option tab while the game is launched. But i'd rather have it work on first launch.

There might be an internal gameini setting overriding AA to avoid issues.

Judging from the symptoms, that's almost definitely the case. When you open the graphics config mid-game, it switches the options to those currently selected in the config--so it might work, but clearly AA has been disabled for a reason, so you're probably out of luck. When in doubt, you should also check the wiki page.

The only thing in the GameINI is Real XFB, apparently for the videos. That would affect a lot more than just antialiasing.

Honestly I'm against turning on RealXFB in the INI for issues like this. It cripples a lot of functionality without telling the user what is going on so they can correct it. But meh, Linktothepast does all the work.
