I would think that except other 3D games don't or seem to not exhibit the same behavior, I've only noticed it with games running on 3DFX hardware. Speed Up, Tekken Tag and Die Hard Arcade all keep running the way they used to. I know Windows Update can't actually affect MAME but perhaps it affected something in Windows that the 3DFX driver depends on? I don't really know what else would cause these fluctuations since I've mostly turned off all unnecessary background services and it worked fine before
Here's a screenshot during one of it's 'fluctuations' which happens every other second or so, no other processes are running from what I can tell and I can run it unthrottled just fine without having it dip all over the place.
