The -mt switch controls only if the final upload of the completed game frame to your video card is threaded off (rather than MAME waiting for the video card to complete it). If you're using a half-decent PCI Express AMD or Nvidia card, this likely does nothing except cause a couple of MAMETesters bugs and there's no performance benefit to having it on.
What the -mt switch does not control is if individual drivers are allowed to marshal additional CPU cores for their own purposes. So, for example, NFL Blitz will cheerfully use your other cores even with -nomt.
