using internal and external graphic cards - P3D v3 freezes

[Ric33]

I tried to use
internal GC (HD 4600) with one monitor (add-ons etc...)
and
external GC (Nvidia GTX770) with second monitor (dedicated to Simulator when flying)

I would say everything works including FSX-SE.

BUT after start, P3Dv3 freezes on scenario window and crashes after some while.

I did uninstall and after new install, P3D runs but once and only for 2-3 mn.

Is there anything to be done to improve it?

I had a similar problem until I decided just to use my GeForce card for all my monitors (4 of them).

The workaround at the time was to boot with the internal monitor switched off. Then with P3d setup to load to it's startup window, you load P3d, then at it's scenario screen, you turn on the second monitor. Windows refreshes everything with the extra display now enabled. Then select your scenario and continue.

So thanks for tip.
finally I have switched off the internal Intel and installed one more PCIe : Nvidia basic Geforce 210.

Now it works perfectly using FSX-SE and P3D v3 as well.

Simulator on GTX770 and add-ons on Geforce 210.
FPX on P3d : 35-40 fps
