is this an officially supported system?
If so, you should be able to report to GTAC and see if they can reproduce it.
Production: NX10.0.3.5 MP16/TC11.2
I'd rather be e-steamed than e-diseaseled
this is a built in graphic chip and while a session lasts NX is working fine as supposed.There is no other graphic chip on board so the reason will not be found in the switching between cards.
I suspect the reason in some kind of sleep state that is triggered by the graphics card and then NX reacts in a manner, that it crashes. no other program does that, especially no commercially available one..
