NIS 2012 ...general lag?

Hi guys, sorry I dont post much here but yesterday I installed nis2012 but felt a "general lag" or "slowness" on my system..hmm...hard to say...also thought cpu usage may have been a lil high..anyway....just felt something wasnt as smooth as nis2011....i went back to nis2011 for now...maybe i just need to give 2012 a longer try

 

anything i can check or provide to help fix that...would love to use nis2012... anyone else notice a lil slowness or a higher system requirement?

 

my specs... amd quad 2.3ghz , 6gb ram, windows7 64 bit.

 

thanks
