There are another graphic problems:
* when I fly Spitfire, I can't see shot traces when I use machine guns. There aren't any problems with other planes
* in PILOT / PLANE menu, 3d model of my pilot and plane disappears after short time, then my PC crashes...

Could anyone help?

Nobody has tracers in Spit Mk.IIa. It is a bug.

The crash is very strange. What is the crash exactly? Does the screen go black? Do you have any specific error messages showing? Blue screen of death?
