I gotcha. Is there another workaround you might suggest that wouldn't involve calling the engine with any arguments? The exe-calling-exe trick tends to break down with publishers' wrappers. For example, we tried this with our WildTangent build of Wonderful, but they told us that their wrapper went haywire. (Same with Reflexive. Eventually, we upgraded Wonderful to A7, bypassed the need for an exe, and things worked perfectly -- http://www.reflexive.com/TheWonderfulEndoftheWorld.html?related=12.)

Thanks for any suggestions -- I think the ability to turn antialiasing on would make our upcoming game more attractive to players.
