I just ran DxO PureRaw2 against an RW2 file and got no more than a black frame with red, green, blue, and red lines and boxes. I don’t understand what happened.
Are your GPU drivers and other system drivers up-to-date?
As far as I know they are. I’ll have to check. I recently upgraded my GPU and this wasn’t happening after the upgrade. It just started in the past couple of days.
