Match Engine is Laggy

Same for me, I've got software monitoring the frame rate which sticks as a solid 60FPS and my CPU is at 15% load and GPU at 22% load at 4K yet still stuttering a lot. It's no better at 1440p either with even lower CPU and GPU loads which suggests it's a game issue. 

Hello, when I do a match 3 d it stutters at the level of sound and image ... it's unpleasant

Could we get a little bit more info, please, if you'd be able to take a video of the issue it would be really beneficial.

And does this happen on every highlight speed, or just certain ones?
