Tech Help

Not sure exactly where to post this so figured I would try here first.Ok...I just got a gaming keyboard and mouse...played a few games and noticed that mouse was kinda glitchy...a little jumpy....could use some ideas for settings.I have a ROCCAT ISKU keyboard and ROCCAT XTD mouse....I'm not very tech savy so could use some advice for settings..primarily on mouse,it was tons of options.....Thanks
