Hi,
yesterday I tested the MP in the last beta and I found that on some servers all the engines excessively smoke more than elsewhere.
While taxiing down the runway behind the other aircraft, this has resulted in a drop in framerate on 20 fps which is a disaster.
I started searching and found the file exhaustTrailAir.lua, where its parameters are causing a huge drop in fps.
Actually, just change one value and all of the sudden after the problem.
In the single player game is the framerate almost constant, but due to the control integrity, you cannot use multiplayer.
Please ED improve the behavior of the smoke, thank you very much.
