: My experience running Marathon 1 on OS X on an upgraded beige G3 has been
: mixed... The performance is usually good, but it tends to drop down to the
: single digits in some situations, which I have yet to exactly pin down.
: Two things that usually bog it down are large numbers of active monsters,
: large numbers of projectiles being fired, and monsters being awake but
: unable to move (even a single monster in this position causes a
: significant drop). Sometimes, the timing gets messed up, and the game runs
: slower, not as in framerate, but events happens slower. It is possible to
: switch out of the game to other applications (which was already possible
: under OS 9, but X makes it so much smoother), but you must use shift-5 to
: be able to get back into the game. Marathon Infinity inherits all of these
: points except the major slowdowns. Aleph One has some OpenGL issues in
: Classic, and I don't believe the Carbon version has ever fully worked for
: me.
Is OS X even supported for your computer? I thought the Beige's were out.
But anyway, what version are you runing? Chances are if you haven't upgraded to OS X.1 yet you should wait until you have done so. It will probably run much better on X.1, I'll know for sure on Monday.
