For some games I emulate, for the most of the time they're a satisfactory 60fps, but after two or so minutes (it is almost a cycle) it starts going down (up to 30fps) with resulting slowness... other than that it also seems to do so when there are a lot of sprites etc. Happens with games such as Aeon Flux and Futurama.
