I pushed F12 a few times in our last DayZ mission, trying to take some screenshots but when I check my Steam account no screenshots are shown. Anybody know what I'm doing wrong?

Check the Steam screenshot folder in your computer. Here is my file path.

C:\Program Files (x86)\Steam\userdata\60164562\760\remote\221100\screenshots

Does your audio make flash power-up sound when you press F12 ?

Mine does not start functioning until I press the button twice.

I looked for that folder and couldn't find it. I was always under the impression that screenshots were saved on the cloud somewhere. I didn't hear any sounds when i pushed F12 but I'll try pushing it twice next time. Thanks for the reply.

Go to:
C:\Program Files (x86)\Steam\userdata
The number used for the next folder is likely different than mine. I think the number is associated with your individual Steam Account.

I looked within the DayZ game and did not find the key binding to screen shot. It appears the default Steam key binding is "F12"
