I just updated to the latest beta. I was having the same issue in the previous version: pressing the designated screen capture key says that a screenshot was saved, but no file appears in the specified location. Any ideas?
I have had that problem before, I just uninstalled it without saving my settings then reinstalled it again.
Did you check the Information-Dialog if there were any active 3D processes recognized by MSIAB/RTSS? You'll find the dialog by clicking the bold i on the right side near the top. After it opened, scroll down to see this info. If you find some unwanted processes there, keep the dialog open and move it to the left. Open up RTSS by clicking it's tray-icon. Now for every unwanted exe-file: * copy the filename from the info-dialog to the clippboard * In the RTSS windows click the big + (down left) * paste the filename * hit Enter and don't care about the path * set detection level to "None" After that restart MSI-AB once If there are no more active 3D processes in the info you'll be able to record and screencapture the desktop or your game you'll going to play.
