me too. Ive followed tutorials and gotten the mouse to work great and everything works fine, but the problem is that the sensitivity intervals with first person games is far too touchy and I cant figure out a way to make it better. Example: bioshock works great but I have to turn the sensitivity all the way down. turning and looking around is very slow, but it is still hard to aim because gently pushing the thumbstick still moves it too fast to aim accurately. very annoying indeed.
Also on a sidenote, games like oblivion, portal 2, and others have been very weird with the ps3 controller. also bioshock doesnt support it natively either. I found a controller driver out there but it wont install because snow leopard wont nstall the damn .pkg file! so f'ing annoying lol. I may just buy an actual mac/pc controller and only use controllermate for non-first person games.
