ok,well i dont think it was all the mouse .while in game im getting motion sick, cant focus during/afterwards and just having some problems playing in general. i did refresh to 75 hertz but i dont fully understand why or if i CAN on this monitor but it didnt work anyway.

this flat screen is about 5 years old so i could use another and ive seen some good deals out there.can any one tell me what to look for when shopping for a good one ? im gonna go barf now ,hopefully i can work this out.
