I have a AMD Ryzen 5 1600 with a GTX 1070 8GB video card running Xplane 11 at a slow frame rate because I have a full cockpit with 3 external screens.  I have a laptop that I was thinking of using as a master to run the controls and Flight only maybe the pop-out GPS.  Currently on the single computer Ryzen 5 I'm getting about 20fps.  Will this use of a second computer laptop increase my fps appreciably on the AMD 1600 if I use it for external views only?  I'd like your opionion before buying a second copy and ripping apart my cockpit to accommodate this.
