I also tried lowering the resolution. The lag reduced significantly, but mouse movement still causes lag.
Yes, I've experienced noticeable improvement by lowering resolution. However, moving the mouse to even deploy MCV makes me afraid of the lag I'd experience if I was attempting to operate a full-sized base.
What I find to be the most-odd is the scrolling of the mouse seems to be the only unaffected object in the lag. Unit movement, building/training queues, and resource/money updates (like when you first start level and starting money is added) all run slowly during mouse movement. However, you can freely move the mouse around the screen with ease.
