OCZ is introducing a new piece of hardware aimed at gamers, a mouse they are calling the Dominatrix. While sometimes I question the naming convention that hardware vendors use, OCZ's new mouse certainly looks nice on paper with an awful lot of customization. The mouse features dpi settings of up to 2000, which can be controlled individually for each axis all the way down to 400.
It supports a high poll rate, helpful for those who want ultra-sensitive control, and has adjustable weight as well. Like many high-end mice, it also supports software profiles to configure it for different applications at different times. You can read more about the OCZ Dominatrix in the press release.
Just as important as having a system fast enough for smooth play is important to gamers, so is having input devices that are snappy and responsive. The mouse is the one most often targeted for improvement, as a lot of stock mice won't have the tracking capabilities people want for games.
