Wing Vortex


Recently, I realized I have not seen any wing vortices in a long time in FSX. I may have inadvertantly changed something I shouldn’t have. Can anyone tell me what may have happened and how to turn the wing vortices back on. I have looked through the FSX.CFG file but can’t see anything that looks like it may be the setting.

Any help you can give me would be greatly apprecieated since I really miss seeing them.
