I have a razer blackwidow x chroma and a razer deathadder chroma, but I don't think that's the problem. I can see this kind of arrows when I right click on the floor, but the soldiers start to move 3 seconds later.
It's very simple, I chose a unit and if I want to move it for example to get wood, I right click and it takes 5 or 6 secs to start moving to the tree. I can record a video if you want
