Tweaks for Windows 8

Hello:
I just came from using windows xp to buying a new laptop with windows 8, I7 Intel, with 8 gb of ram, and discrete graphics card.
I would like to ask if there is any tweaks to the computer that I can use to better my latency....there is scratchy audio and the best I can get is 12ms latency using an Audio 2 DJ soundcard.
With my old computer (P4 and XP) I never had any problems, Im disappointed right now! Thanks for all the help!
