Are your cores throttling up and down with the load? In Windows you have to go in the Bios and turn off CPU throttling. BAsically the cores slow down when the are not under load to conserve power… this shows as high ASIO load in Cubase. IF you set the cores so they don’t throttle you have maximum core speed available at all times and you shouldn’t see those “logarithmic” load situations. I might be wrong but this is what it looks like to me.
This must be because you have a very high clock rate. Also, take a look at the CPU graph and see which cores are being used – you could probably have a lot more power if Cubase took advantage of all cores (unless four cores somehow works perfectly for Cubase).
It’s easy for Steinberg to say “Just use a CPU with a higher clock rate!”, but that’s not dealing with reality for tons of its users. Let’s say you have a Mac and you need massive processing for other programs like Final Cut Pro, Pro Tools, video graphics applications, etc. – you need the high core-count systems because all of these other programs take advantage of that and Xeons are the only processors you can get for Macs (everyone: please do not start a Hackintosh or Mac vs. PC discussion – this is completely separate from that, and these problems are with any multicore processor on any platform). So if you’re a Cubase user you’re screwed in that case. Since every other DAW many of us have tried here can take huge advantage of multicores/threads and Cubase doesn’t, there’s a very clear fault with the basic engine.[/quote]
