Ok, here's some info.
The symptom is: a window w/ 3d animation runs fine on the lower row. When displayed on the top row, it has a subtle "jerk" that occurs every ~1 second or so. When the window spans both the top and bottom row, the program reports the same FPS but there is some significant jerkiness to the animation.
Motherboard: ASUS Sabertooth P67.
Proc: Core i7-2600 3.4Ghz, 4 core
Ram: 16GB
Graphics: Two VisionTek 7750s
OS: Windows 8.1 x64
This is a dual 5x1 setup where each card controls one row of 5 1920x1080 60Hz displays. Top card controls top row, bottom card controls bottom row.
Using Eyefinity to configure two SLS (5x1).
Catalyst 14.12.
AMD Driver version 14.501.1003.0
One additional detail is that the top row of screens are physically flipped 180, and I have configured the 180 filp in the Catalyst Control Center.
