I recently bought FPSe and tried it with my PS3 controller. The controller works very well with it since the Playstation has kept all their controllers the same design (as opposed to using the PS3 controller with the N64 emulator). I've only tried 2 games so far, Final Fantasy 6 and 7, and FF7 lags a LOT and eventually freezes. I imagine it will work well with less graphic intensive games.
