like continuously calculating trajectory? continuously tracking a target using vision algorithms? running 6-8 PID loops at 50Hz? get the point?

it was the 16-bit PICC I think and the vision code was so slow as to be almost unusable - and the camera did some of the work back then

be amazed, have you seen all the other crap running on that processor? but I basically agree, it should be enough.
