Just wondering (really no offense) how come the controls for AA etc. are activated on the launcher?
It was added to the launcher when it the game code was in development, however the game code never got enough testing to be allowed into SVN. I had it coded in for testing as part of my Xt builds back in early 2007 but it just didn't work 100% in my tests, there wasn't enough tester feedback on those features, and I had largely stopped coding on Xt before the code testing was done.
As for what worked (or didn't) in that old code... the SDL code should have been working fine for Linux and OS X, however on my test system (arguably not very good) it often failed to use AA, but the fail-over code worked fine at least; and the Windows code was generally good I believe, but it in tests would almost always cause a BSOD when the game was run a second time (again, likely a problem with the test system than the code). All of the code is still alive in the Xt branch in SVN though, it's just not build-able and no one has ever gone through to port any of the fixes and improvements from my Xt code to the general code base.
