You should be able to limit analysis for this type of detection to only the input leading up to a kill/hit and ignoring everything else. The majority of the time players are not shooting could be used to do the analysis with plenty of time to boot midway in a round let alone a full game.
Also simple analysis of only the input streams as you stated really doesn't have to do with the phys rate of the game server and should be alot cheaper computationally. It can be offloaded to another process even if it was found to be too impactful to run alongside the game server directly. Something all those extra cores might be good for.
