We have found that for the best performance with MachFive, Symphonic Instrument, Ethno Instrument, and Electric Keys on Windows systems that you should update to the latest drivers for your graphics card. This includes graphics cards by Matrox, ATI, NVIDIA, and more.

Check the website of your graphics card's manufacturer for the latest drivers. Keep in mind that some manufacturers don't have separate updates for every card they make; rather, they provide one update for a whole "family" of cards. So when looking for driver updates, check to see if your card is part of a series or family of cards.
