Maybe… I don’t see anything in the release notes that suggests a change in this area, but check out this Windows 10 Task Manager CPU performance screen:
While my current project shouldn’t be super heavy in that it only has 7 frozen tracks, one track that isn’t froze (and has a couple of plugins in it), plus 7 group tracks (including the Stereo Out), all with plugins in them (including Ozone 10 on the Stereo Out, and several of the group tracks having IK’s Fame Studio Reverb, which isn’t super lightweight), it is running at 96 kHz on my i7 5820k system, and I’m pretty sure it was having a tough time keeping up when I left it last night.
The reason I paste the CPU performance screen, though, is to point out the relatively uniform levels of all 12 of the logical processors. While I might well be forgetting how this project was running at the end of yesterday, its running better than I was thinking it would, and the question on 13.0.40 feeling snappier here, triggered me to check out this screen. Most typically when I’ve looked it in the past, the first CPU has shown significantly higher levels than all the others. For example, check out the similar screens I posted in this thread early in Cubase 13’s life:
Even in the case with the workaround of creating a gratuitous HALion track with the focus that at the time was making things spread out a bit more evenly, the first CPU still had a significantly higher level than any of the others. This time, though none of the twelve are significantly higher than the others.
It’s way too early for me to answer definitively that 13.0.40 is feeling snappier, but this much more even CPU load picture is at least encouraging if it isn’t just a fluke in starting today’s session.
