Mouse Lag
This video is for a lagging mouse during game play; Also, do not forget to go back in the program, ICUE, and go to default when you are not in the game anymore... I had two buttons set up as CTRL and SHIFT (toggled). Anything I selected or typed, used these keys. What a mess... or just make sure these are turned off when exiting your program!!! Otherwise, everything you type and click will be CTRL and SHIFT. Not good.
