I have a three screen cabinet with a heavy hitter PC running Windows 10 64 bit, including a GTX 1070. I am running VP 10.4 and only using VPX tables. My playfield is a Samsung 4k monitor. When I am not using exclusive fullscreen mode, I get stutter in several of those tables. When I changed to exclusive full screen mode, the stutter went away completely. I should add that anyone who thinks there isn't a difference between 1080p versus 4k in VP, they're dead wrong. These new tables in 4k are a thing of beauty. Thx.
