cubase and Yamaha 01v96i

For anyone considering using this combination check out some latency figures as at the moment i am using win7 64 on a i5 PC with cubase 32 bit and the latency is twice that of my old M Audio 18/14 firewire interface, and even at 96 samples cubase is reporting a latency of 15, done a session last week with a drummer using this who complained about the delay in his cans, I have never had this problem with the old 18/14 so will replumb my system to use this until i can sort out the problem, if anyone has any ideas please reply
