Game graphics crash but not launcher

[AKA_Tenn]

Every 20 minutes to an hour or so, only in british aircraft (spit/hurri), my game freezes, but i can still press escape, and quit normally with the normal GUI... so i don't get crashdump files so how to i report this, or is anyone else having that issue...

also one time i was flying the E4 and my prop pitch, even in manual, stopped working, then alluva sudden my graphics all glitched out like this

in that resolution too, when i normally play it looks like this


I use a EVGA GTX570HD 2GB I7-2600k@4.5GHz G.Skill Ripjaws 8GB

currently using the 2.85.38 videocard drivers.
