Well, I don't know if it was answered already (or, more likely, if there is even question), but if you want to take screenies with ShadowPlay enabled you can use ReShade + SweetFX.

Perhaps not the most valuble information for you, Serza, but still.

I tried ReShade with ArmA, didn't quite like it too much. Preferred the vanilla touch (not to mention ArmA being already hard enough on your CPU, without the extra load)...
So, nope. I'll stick with ShadowPlay and videos 
Did you ever read the OP of the Lounge thread?
Oh, you and me both, sister.
Well, in this case I am. I'll take pity on you and quote myself:
I did it as a joke, as I often do.
I do have a reputation to maintain.
A funny one, aye? I understand, lethallan.
And who reads OP, anyway? Not me...
Anyone encounter the quiz man behind the wall?

Woah. In Skyhold, I assume? Creepy.
That reminds me I was such a creepy lurker... some 0 post random person knowing all of you and the things you'd done during the first 200-something pages 
Aren't you a nice little slightly creepy Necromancer, huh....
