Hello, so I think, that problem with CTD is solved( http://forum.avsim.n...-after-takeoff/ ). It seems, that CTD caused IVAP, I tried to fly with external mode of IVAP and everything was OK, but IVAP crashed, fortunately only IVAP not FSX. But I have another problem, most of the time when I minimize FSX or I hide/unhide IVAP, the graphics is not rendered correctly - here are the screens http://imageshack.us/photo/my-images/845/2011824111820709.jpg/http://imageshack.us/photo/my-images/685/2011824111846907.jpg/http://imageshack.us/photo/my-images/13/201182411194394.jpg/ sometimes, when I repeatedly several times minimize and maximize FS, problem is away, but sometimes there remains only black screen, and I hear only sounds of aircraft. Any idea how to solve this problem? Thank you for your replies.

you got any fps limiter ?

No. I have this problem since I own the NGX.

No.

It sounds like the display refresh problem. Oh crap sorry I replied to a different post. there is a same issue under video cards section. Sorry sorry. Someone will help you out.

That´s ok :)But have you got any idea, how to solve it?

These are artifacts I suppose ?

I do not know, but maybe they are. But I have this problem only with NGX.
