Flyingiron Spitfire Effects

Still i got no backfire and smoke when start up of engines.
No flames at all.
I use Windows 11 and last MSFS update.
Anyone else?
Thanks

I believe the effects broke in SU9 i’m afraid, the devs are aware of it.

I have the flames but no smoke nor backfiring. The flames reppear consistantly when I do a deadcut on the magnetos

Ok Guys thanks for the info.
