Killer Instinct 2 and MAME32 aren't getting along

[potskies]

I've been playing KI2 (v1.4) with MAME32 for a few months with no problems at all, but a few weeks ago it started to stutter every few minutes and now its lagging hard... constantly. And it also seems as though the graphics have suffered a bit. Although, that might just be because its going so slow I have a lot more time to look at each frame.
I love this game so very much and wish to continue my quest for the insanely hard to input 72 hit ultras (damn keyboard and being all reversed).
Any help would be appreciated to the utmost.

And by the by, none of the other versions are any better.

You don't say what version number of mame you are using. If its a relatively new version then try using the refreshspeed option as it sounds like a synch issue. Basically if mame is running the game at a different refresh rate to the games native refresh every now and again the video and sound go out of synch with each other causing mame to lag as it throttles the video to bring it back into line with the sound, this is a particular problem on fixed refresh displays like LCD screens. (did the problem start after changing your monitor?)
