Hello Everyone Razer Community!

I recently bought a Razer Core to connect to my Razer Stealh.  I also connected an external monitor to the Razer Core.  I bought God of War via Steam.  Here is the problem, when running the game via the Stealth with the Core on, I encounter no issues.  The game is smooth and graphics are awesome.  However, when I move the window into the external monitor that it is connected to the Core, the game slows down tremendously and it is barely playable.  Any ideas?  Is my Core setting incorrect?   Your help is greatly appreciated!

Thank you!
