Buzzkill himself has been kind enough to tell me much the same thing on the Booster forums. Increased FPS is likely to alter the calculations the bots make. I'm going to try for a target FPS of a stable 100 (at the moment it can and does run up to 250FPS) and see how that works. I have also increased some of the bot levels simply to make them react faster.
I'll let you know how it goes.
