Well, I thought I knew what I was doing :-)
I've used various applications to make screen videos, but none seem to work with GW2. Or, rather, I'm doing something wrong. Here's what happens with 4 different screen video applications I've tried:
1. Start video app. and begin recording.
2. Start game.
3. After recording notice that all the app recorded was my desktop.
I did, however, get good recordings when I opened GW2 at less that full screen. Then sound and video worked fine.
Have I answered my own question? :-) Or is there a way to play full screen and still make video?
One other thing: I use Razor Game Booster. When I try to use its video feature GW2 crashes, although it makes fine screenshots with no problems.
Thanks for any help, ideas, and advice!
