I get a big FPS hit during the aircraft engine start up sequence.  It appears to be the smoke.  My FPS goes from over 100 FPS down to 4 FPS and then after engine start it goes back up!!!  Anyone know how to reduce or get rid of the smoke animation?  I love how it looks but I would like to stop the huge FPS hit.

TIA

If anyone else is interested, I have created a small mod file to reduce the amount of smoke during engine startup in WAW and reducing the FPS hit that occurs.  Here is the link:

https://www.mediafire.com/download/y4w555czfdkj65o/#WAW_Startup_Smoke_Fix.7z
edit: new link in reply #8.

Just unzip this to your jsgmemods folder and then activate...

Note: This is just a modified version of the built in 4.12 effects as referenced above by vpmedia.  I did not create the files (I do not know who did), I just modified them.
