My PC: Intel Quad 2.6GHz 4Gb RAM Nvidia GT 240 Windows 7 64 bits My GameEx doesn't run smooth and I've disable every effect, sound, video... The movement around lines in menus is slow and with lag. What is more: If i launch MAME with it, the game freeze for a moment each 3 o 4 seconds. If I run MAME with the same configuration but without been launched from GameEx, it runs perfect. I think that this PC should run GameEx perfectly, isn't it?
