ASIO spikes worse for me in C7.5 than Nuendo 6.

I have done alot of testing to compare Cubase with other daws, FL studio, Presonus S1 and Logic.

Cubase spikes 3 times as much and uses more resources than all the rest, its not even a question if but more why.
My theory is that the syncrosoft protection is wired through every feature thus draining more resources and lagging it all down.

I have the same issue and it is extremely frustrating. Periodic ASIO spikes. Seems to be related to USB devices. Apparently when I unplug my Virus TI synth, things get better, but not completely.
