Gives the vehicle trails more of a sense of dust particles lofted into the air and settling back out. As speed increases, they can get quite long, but framerates seem unharmed due to the reduced number of particles.
This is the first of a series of mods I would like to make for the particle effects, making them more solid and persistent, which I think is both more realistic and makes the world seem more properly-scaled, and is also just plain cool.
To install, simply drop into your DCS World folder. Backups are included.
I slightly decreased the number of particles in each effect, so there shouldn't be any real performance hit, but if you have any suggestions, ideas, complaints, etc. please see the thread I mentioned above. And of course feel free to modify them yourself, as well.
Update 4/15/13: Toned it down just a little bit. Made them fade out more gradually and last only 75% as long. Looked kind of silly to kick up that much dust on grass.
Update 4/17/13: Reduced sensitivity to wind and moved spawn point for wheeled vehicles - Was causing only front wheels to appear to kick up dust when going perpendicular to very high winds.
