I used to have 2x 1080p monitors running off a 970 through HDMI and DP.
I since replaced one of those monitors with a 21:9 2560x1080p.
So now I have one ultrawide and one 16:9 running off of a single 970 through HDMI and DP.
With this new setup, I have regular occurences of micro-stutter on the ultrawide if both screens are running at 60Hz - it lasts for about 2/3 seconds and it is really annoying.
If I run the ultrawide at 59Hz, the microstutter becomes a lot less apparent, but gameplay still is not smooth 100% of the time. Note that with an FPS counter running, the FPS does not drop during these instances of microstutter.
Again, this issue was not present when both monitors were 16:9 @ 1080p.
The Ultrawide is currently running at 80Hz, the other 1080p at 60Hz. Microstutter remains but is not anywhere near as bad as it was.
Does anyone have any idea how to solve this? Please do tell me if the explanation is not clear enough.
