First day and I am seeing a significant CPU usage performance improvement with N15, about 25-30% improvement, I am able to go from 500 to 250 with soundcard asio buffer, I am not running large orchestral templates, just Maschine with 4 tracks running, Falcon with two augmented orch patches, CSS e…

No, unfortunately not. Progressively worse since N13.

I am finding greater stability, with N15, particularly in relation to having multiple projects opened, and with activating and deactivating projects. Also, unloading projects is far quicker and the program is less prone to crashing.

Its gone both ways for me. A few projects are better than they were in Cubase 14 for me (I just switched to Nuendo) and the majority are the same. In general closing seems to be a bit faster though.

ugh - I will monitor this over time, I did not start a new template from scratch, I opened a N14 project and then saved under new name and folder, and noticed the improvement,

Please understand that I absolutely love the updates and features in N15. Steinberg always delivers so many wonderful benefits to the workflow. I just wish they could address performance - a topic that is being addressed in another big thread. Steinberg are aware of the issue and, unfortunately, to…

From my experience, performance is something that is addressed over time. We are only just in with V15, for both DAW’s, and there is a way to go yet, to address performance issues, and with so many CPU’s to support and ever changing OS requirements, staying on a prior verion is an option. For me, …

Core handling in coming updates for Win 11? Cubase

Is Steinberg planning to let Win 11 manage the core handling in future updates of Cubase/Nuendo? It is well-known that Cubase doesn’t do this brilliantly today, and that much can be learned from Reaper, which leaves the core handling to Intel’s Thread Director and the Windows scheduling, instead of - like Cubase - trying to achieve this on its own. To me, this is the one and really only area where I see room for major improvement in Cubase. It would be super useful if Steinberg could let the u…
