| ASPHYXIA does not use this particular circle algorithm, ours is in assembly language, but this one should be fast enough for most. If it isn't, give us the stuff you are using it for and we'll give you ours. | ASPHYXIA does not use this particular circle algorithm, ours is in assembly language, but this one should be fast enough for most.
