Ok, I am using WindowFX 6 on Windows 10 Pro.
I have two Nvidia GTX 650 graphics cards attached, each with 3 monitors.
First 650 runs 3 monitors at 1920x1080. Second 650 runs 3 monitors at 1600x900.
Wobbly Windows runs jerky. Motion is rough.
If I disable the 3 monitors on the second card, all is fine, motion is smooth.
Up to date NVidia drivers, 16 GB DDR3 ram, and a 6 core AMD Phenom CPU.
Any ideas? Neil?
