I play the maps as they were made. Maybe because I find it too bothersome to go find the beatmap's folder and delete everything there.
When something lags me, I just wait for my computer to get "better" (restarting often helps), or just play something else. Storyboards generally don't affect me though; whenever I get lag spikes, I get them globally, and I can get through any skin pretty much fine (except of course if it's an horribly horrible skin, but I don't recall any, probably because I don't play as much anime as everyone else).
