I distintivly remember my first time agaisnt Neo Ridley in Fusion, and everytime i hit him with a full charge shot game stuttered like hell.
Diffusion missiles too.
Ok it ran at 60 fps 99.95% of the time then lol.
My biggest pet peeve is people who think 30fps is a problem.
Nobody's telling other people to not buy the game, so I don't see why anyone else would care.
