Cheers Gregster! I forgot to add bioshock infinite, which is one I tested a bit more. I too found stutter with that, and it does feel like it's when you go into a new area. This was one of the first games I noticed that this only happened with SLI though. Have you tried bioshock on one card only? You should fine its smooth as silk.
Also, please do try out the xbox 360 controller with a few games. Slow panning round in BF4 is where it's showing a real judder problem.
It's only teething troubles really. I've had this monitor a week tomorrow, and these minor niggles aside, it continues to impress me. Titanfall at 120hz with gsync is amazing as just one example.
So I have tried BF4 on an empty server and used a 360 pad to pan round and no stutter or jerks at all. I have frames capped at 135 and running full ultra at 1440P and honestly can't see any faults. I have a solid yellow line and where I am frame capped, the green line is up and down. Maybe some more testing needed but you sure it isn't server/ping/internet problems you are seeing?
