Some guys flying in WB created 'frame rate' friendly effects for bombing targets, they also employed 'night friendly effects' when going on night pathfinder raids in the S3. SOme others tweaked the engine fire/smoke effects to the point where it seems like a nice fire that you can BBQ your steaks on

.
Definitely worth to it for tactics defending a field against Tanks, Jabo guys and bomber guys. The smoke will alert you that someone is attacking a field since you too will see smoke in the distance

. And fun to see when you are on the offensive.
The way WB is set up is you have a minute or two of target burning, followed by a few minutes of smoldering smoke....
