Like many players, I suffer a major frame rate hit near large airfields and large bomber formations when the ack is firing. It would be nice to have the ability to have a slider in the graphics options to reduce the number of tracers drawn on screen. It would work best if the slider adjusted the tracer percentage reduction not by the range of the guns to you (like trees), but by adjusting the density of tracers visible evenly across all sources in normal draw range. IE: If I'm flying over a field with a fleet off shore 5 miles away and my slider is set to 25%, both the base and fleet ack would show 25% of the normal tracers at the same time.
