It's not Resolume, and if you checked ALL of your devices inline from your computer to the output screen, then the problem is with either:
A.) Your computer
or
B.) Your output hardware (LED processors, converters, etc.)
But flickering is 99% mismatched framerate issues. so you might try other drivers first (probably not the issue) or other processors and converters to see where the problem is. Start at one end and start removing/replacing parts until the problem goes away, then you'll know what the issue it
If it was a Resolume problem, there would be thousands of people complaining about it (myself included lol)
