Cubase 10, Buffer Size and Real Time Performance Issue Ryzen Threadripper 1950X

[Sh4d0wStrider]

Hey guys so I have a bit of a problem with my latency and buffer size and real time performance.
Not sure if this section of the forums is the correct place to post it but if its not please advise me where to re-post it.

Firstly my hardware is a Windows 10 64 bit, up to date, latest drivers on everything double checked em.
Cubase 10
CPU - Ryzen Theradripper 1950X overclocked to 4.0 Ghz
Ram - 32 Gigs 3000 mhz
4 SSD's - WIndows is on SSD1, Cubase on SSD2, Samples on SSD3, VST instrument installations on SSD4
My audio interface is a Presonus 1810c and it has three inputs pluged in 2 x Guitars and 1 Mic, which are not constantly enabled in Cubase for inputs.

My problem is that with a buffer size of 1024 I can at most have 24 vst instruments give or take with 8 EQ effects total before I start hearing clipz and hiccups. I make mostly orchestral, trailer music and I think that 24 instances is a little bit too low for this big of a buffer size.
I ran latency mon for 20 mintes and it showed no problems and perfect results. I tried disabling certain devices, functions but had no results including Wifi, Ethernet connection, plugged in devices, etc. but nothing helped. I want to get to at least 512 buffer size with 30 vst instruments without hiccups and I know it is possible but I have no idea where to look and what to fix anymore. So I hope to get some assistance.
Please do tell me if you need me to post more information or test results etc.
My CPU has never gone beyound 10-15% usage during play nor when I play and try to record something through MIDI or the inputs.

Doesn't surprise me, to be honest. Getting performance with loads of cores against getting single core performances is surely always a bad thing in regards of real-time application.

I wouldn't touch AMD hardware with a ten foot pole.

I've always been a bit that way myself, as far as CPU's go it's Intel or nothing as far as I'm concerned, and Graphics cards always NVIDIA, just my personal opinion of course. Way back in my gaming days people would go for AMD because of cost, always ended in trouble and much lower performance, things mat be different now, although I doubt it.

All the best to the OP, hope it gets sorted.

Are these sample playback instruments or emulations? Each of those cores will do a great job with an emulation but sample playback end up being about memory controllers and such like. I am not sure that is AMD's strong point.

Also did the audio interface ever do low latency? I can get similar track counts at 254 on an ancient Intel but with a RME card. I wonder if the card mighr be your issue.

I switched from Intel to AMD due to pricing and issues with my last i7 8700k, it was a real nightmare with it so I plainly returned the whole system after 2 weeks of nothing but problems with it and replaced it with the threadripper.

I have been thinking of getting and RME with each passing year and the investment seems like a good idea, but I am unsure of yet whether to go for their USB ones or their PCI ones. I use mainly Kontakt Instances with different orchestral vst in em (Cinesample, Metropolis, etc.) I have 3-4 tracks for my guitars which I directly record only with a Guitar Rig 5 on each one and a single Ezdrummer instance.

I used to have a UR22 MK II but it started having problems with latency and I upgrade to the Presonus Studio 1810c. The latency issues started appearing in the past 2-3 months so I am more of thinking the reason is either a Windows Update or a Cubase Update. I did not even need to use Asio Guard before for very high track count but now its impossible without it. And using real-time playing has become impossible after I do my initial piano mock up.

Sorry, but that is just a stupid and biased comment.
It is your loss only to be honest, but don't claim it as facts here. The new Ryzens are great for DAWs. My DAW is a "living" proof of that. I used to stay away from AMD but only because their CPU's wasn't good enough. With the new line of Ryzens, AMD is the leader.

You apparently havent got any first hand information about latest Ryzens performance. Or you know little about building a good computer? Have you ever tested a Ryzen 9 3950 for DAW usage yourself?!

My Ryzen 3950 can load more heavy projects with VST's than Intels overpriced and overclocked 9900KS. I have done benchmarks so I can back it up.

A friend of mine is running AMD Threadripper 2950 for DAW usage for years without any issues.
Threadrippers are different than Ryzens in some ways.

Can you share your specifications and your friends? Maybe my issue is with a driver or the audio interface, although I presume Cubase or Windows is the bigger mastermind.

Hey guys so I have a bit of a problem with my latency and buffer size and real time performance.

I bet you're using the Balanced WIN 10 Power plan setting.

WIN 10 Power plan: always use High Performance Plan (doesn’t lower your CPU’s speed!!!) if you use Cubase or another DAW, don't use Balanced Plan.

No, it isn't. It's a comment based on long time experience with AMD hardware. If it works for you, fine, it never really worked for me.

It's also well known that AMD aren't known for their excellent single core performance (especially the CPU in question sucks at it, and that's obviously why the OP overclocked it). Most AMD CPU's provide mutli core performance, but lack on single core performance. If you want to deny that, then I can't help you, because, then you deny facts. And, the authority, and urgency of your reactions tells me that you're the typical AMD apologist. The latter is my personal opinion, also formed by experience.

Back to topic.

I have always used customized power plans in Windows 10 which have everything set to High Performance and all sleep, hybernate and economy funcions turned off.

I agree that Threadripper indeed lacks in single core performance and I am not arguing regarding that. I am arguing regarding the issue that came up with time and how to resolve it. If the CPU was handling 50-60 VST previously on a 512 or 1024 buffer without ASIO Guard and suddently it starts chuckling with 24 VST at a 2048 buffer with ASIO Guard then I doubt the problem lies solely in the CPU and between Intel and AMD.

The most important thing that Minimum Processor State always should be 100% if you're using a DAW.

@Sh4d0wStrider: To be fair, I'm not sure what the problem is here either. I just can echo what I read about AMD processors, also in regards of high performance audio or gaming, and speak from my own experience with AMD.

Hope you get this resolved.

I have, I have always done habit wise, so I do not think the problem is in power settings. Double checked all of those.

Mmmhh ... seems your personal opinion is very special: click me!
