Cubase meter shows ~100% Average load continously, and 50-60 RT load when playing back
10 (20) Cores seem to be working b/w ~20-40% each in task manager
I made another weird observation: freezing one single track (Omnisphere 2.5) in this project does the opposite of easing the resources. The project becomes unplayable (only dropouts, i.e. will not even playback something, meters only flicker). Maybe any hints on this?
I originally thought I was not experiencing any issues after upgrading to 10 Pro when I turned hyper-threading back on my 10core CPU, but something changed since then. I think a Windows 10 update may have broke something. If I do not disable hyper-threading, I get random pops and spikes. I don’t have time to fiddle around with it, so I just am leaving HT off for now.
Not used versions of Cubase 9-9.5. Tried to return to Cubase 10 Pro. I observe, like many here, the problem with random jumps of RealTime Peak, which after 40-50% of ASIO Average loads give clicks and spikes. The system is fully optimized, the latest drivers for all equipment are installed. The situation is slightly improved by disabling hyper-threading support in the BIOS. But does not solve the problem as a whole.
My system: Windows 10x64 Pro v1809, MB ASUS P8Z77-V, Intel Core i7 3770K 3.5Ghz, 16Gb RAM, ASUS Dual-GTX1060, Cubase Pro 10, RME Babyface, AKAI MPK261
I would not like to give similar examples, but I do not observe a similar problem in other DAWs. I also use the latest versions of Studio One 4, Reaper, Reason 10, Cakewalk BandLab. Therefore, I can say with confidence that the matter is in Cubase. In terms of performance and optimization, unfortunately at the moment it is inferior to them all. I look forward to future updates and solutions to these problems. Otherwise, figuratively speaking, why do you need a Ferrari, if it does not go! Good and good luck to the development team, I know that it is not easy for you now.
In my experience, getting real-time peaks is also related to having the GUIs of some effects open, in particular spectrum analyzers (Voxengo SPAN is specially prone to causing high real-time loads). This improves a lot if you disable hyper-threading, as it seems to give more time to the graphics environment.
Yes, I knew that. Doing this effectively brings ASIO Guard into active mode, so it improves the performance as the system then plays at the additional latency dictated by ASIO Guard. Anyway, in my particular system, this still is not enough to avoid getting real-time peaks if Hyper-Threading is active and SPAN GUI is also showing. However, replacing SPAN with TDR Nova (only for the spectrum analyzer part in full screen mode) really does the trick. It seems that Nova is less demanding on the CPU when displaying its analyzer.
im confused is it better to have asio guard enabled or disabled?reason why im asking is im getting advice not too use it because it causes audio glitches but some say its better performance if i do use it.
also how do i tell if i have hype threding enabled or disabled?i never got a reply before from steinberg when i asked.
heres my system info–
intel core i7-5820k-3.30ghz
does system virtual memory paging help ?ive just checked and my computer is set at 2048mb total paging for all drives and thats way below the recommended 4978mb size.i was wondering if this could affect cubase performance.
also will setting my computer to adjust for best performance be much better?i had it set too let windows choose whats best for my computer before.one thing ive noticed is the graphics are less clear when set to best performance…any help
FLS (Local Fiber Storage). The next Windows Functional Upgrade will allow for about 4000 slots instead of a maximum of 128 slots.
Each plugin occupies at least one slot, but there are plugins that occupy more than four slots.
The problem of Windows 10 MMCSS (Multimedia Library).
The library has been moved from user mode to kernel mode as of Windows 10. This now limits the maximum number of virtual processors. The library is currently stable under Windows 10 Version 1809 only if the CPU has a maximum of about 14 logical processors or no more than 32 threads are occupied by MMCSS.
The second problem is not solved by the new and better FLS.
Although there should be a registration patch from Steinberg, but unfortunately the solution is only available on request and not publicly.
What Cubase 10 I do not know exactly, apparently, the program now ensures that a maximum of 32 threads are opened by MMCSS. https://helpcenter.steinberg.de/hc/en-us/articles/115000535804-Windows-10-audio-dropouts-on-multi-core-CPU-setups
In my opinion, this is at the expense of performance. As long as Microsoft does not increase the maximum number of threads runs Cubase 10 with the handbrake on. (Is anyone of a different opinion?) That would mean that the performance of a 20-core CPU from Cubase when using the MMCSS only as a CPU running with 14 logical cores.
Thanks for your POV – after more research, I agree, the MMCSS issue of Cubase on Win 10 does not appear as though it will be helped by the upcoming FLS improvements of Win 10, which will mainly just benefit plugin count. But I am curious if Steinberg thinks otherwise.
As for performance improvements with the new MMCSS approach with Cubase 10, in my experience there IS a performance improvement on a 10-core (20-thread) CPU with Cubase 10 over Cubase 9.5, but more importantly the dropout/engine behavior seems improved as well. Unless I missed a bunch of posts, it seems this thread has plenty of examples of people with improvements, so I think whatever Steinberg did with MMCSS management has helped more than hurt, although there are certainly people facing issues that need to be tracked down and solved. Overall, I think it’s a step in the right direction, but I’m sure further improvements are needed.
My understanding is that the old registry tweaks, etc., are no longer needed… at least in my case they’re not needed anymore, but perhaps Fabio can enlighten us on the latest info? He mentioned various switches to control spawning prefetch threads in different ways, etc… wondering if there has been any further intel on further improvements?
Hello, I thought I’d add my recent experience with a new build. I went from a 6 core intel 64 gigs ram @ 4.5 Ghz setup to a TR 2950x 16 core 128 gig ram @ 4.0 Ghz. On a very demanding large project on the old PC with about 55 gigs of samples loaded the machine was pushed to its limits and would tip the average load meter in Cubase Pro 10 into the red a number of times where all cores/threads would be maxed out close to 100% Cpu load during playing back when viewed via the resource monitor in Windows. So I finished my new build and got it up and running and the same project was around 32 % Cpu load used in windows resource monitor but high in the average load meter in Cubase, but not tipping into the red indicator any more. It wasn’t exactly what I’d hoped for but certainly better. So I then using the Amd Ryzen Master software disabled 4 cores for a test, intern going from 16 cores down to 12 and Cubase now sits around the half way point most of the playback time over about 10 minutes which certainly achieved far better performance in Cubase 10 and more so what I’d been hoping for when I upgraded. Granted I want to take advantage of the 16 cores and not 12 but for now it’s positive results so I’m intending on doing a few more tests to try and park only 2 cores via the bios as Ryzen master needed it evenly distributed so 1 per die.
I just bought a new system with a AMD Classico Ryzen 1920X [12x 3,50GHz] processor and Windows 10.
Can I fully take advantage of the 12 cores, or are there limitations?
Is there something in that context which I have to take care about when installing Cubase on windows 1o?
Pops and cracklings lots of real time peaks after loaded 6 synth!
I7 7820x 16gb ddr4.
Turned off C-State and Speedstep. Same result.
Cubase 8.5 run soooooo smooth.
But this version is horrible.
Not working for me so far.
