2. Enable "Enhance pointer precision"
Set bar to slowest speed that is fast enough for you as faster speeds skip pixels (move your mouse very slowly to see this.)
3. "Start", "Settings", "Control Panel", "Mouse", "Activities" tab
Set "Double-Click Speed" fast as possible in accordance to your natural double-click speed. (Sometimes two single clicks will be misinterpreted as a double-click because your double-click speed is set too slow. For example, highlight a file by clicking on it, and then start to rename it by clicking on it again. If this setting is too slow, it will open the accidentally.)
I downloaded from logitec site. I don't think I explained well. No matter how fast or slow, when I click a tab, cpu increases for FX - mouse pointer lags. Is there a way to increase cpu priority for mouse pointer?
