Hi everybody, posting here in the fabulous AAA forum for some help about a strange graphic "error".
I've been playing IL-2 for years but since last few months I'm experiencing a blueish-violet lighting over any plane as it gets enlightened.. even inside the cockpit!
It happens when switching on nav lights or firing guns/cannons, but also when flying nearby explosions.
Here some screenshots




Does anyone knows what does cause such freaking light?
These are some of my conf.ini settings

Ps: I've got various mods installed in the proper MODS folder.. maybe an incompatibility?
