Hi Rob,
thanks for your reply. As i was intenionally thinking more about Picture Quality, this does make a lot sense to me, as i was one of those who had Troubles in the past with crashes, due to Graphics Drivers.
I know meanwhile how to force a Program to use one card over another, i was just curious if i can see somewhere in the presets which one PI uses, but you gave the answer to this anyway.
Thank you.
CS Frank
