I run Nvidia graphics on both my machines, oldish cards. Be good to keep this thread alive with which ones work well. I'm about to upgrade to C8 currently testing on elements. Wasn't overly happy with performance and issues with my Virus TI have returned. Even when I reverted back. Graphics seem likely as this was the only thing that stayed updated when I reverted.

Unfortunately I don't know who Laurie is but reverting the NVidia Quadro 600 driver to 337.88 did the trick for me too so a massive Thank You Sir!

So I stumbled upon this post and wanted to see if anyone had any issues with Nvidia 650 Ti? Every now and then Ill go rock solid performance to massive spikes on the CPU performance meter in Cubase, resulting in pops. I looked at my cpu monitor and during these spikes my cpu never went above 70% usage. From looking at this thread it seems like Nvidia causes some issues with Steinburg products.

I know this is an older thread but I wanted to briefly give my recent experience with the combination of an Nvidia graphics card and Cubase 8.

For the last 5 years, I've been running an extremely stable AMD Athlon FX 6-core system with an Asus motherboard and a Radeon 6670 video card. It has served me well but certain plugins were impossible to run at low latencies, like Diva in great or divine mode. And it was showing its age with large projects as well.

So I decided to upgrade and I bought a brand new Asus Z97 Pro motherboard and an i7 CPU. I also bought a Nvidia GT730 video card. I always buy fanless cards since the computer is in the studio with me and I need it to be whisper quiet.

Long story short; I was getting random dropouts in Cubase, even with projects consisting of only one track, no matter the latency setting. I tried using different drivers for my firewire card (a TI-based SIIG card that received high marks from other DAW users), turning off Hyper-Threading, uninstalling and re-installing various drivers, changing the power scheme so everything was running 100%, running DLC and other test programs to trace the fault, etc. It was a multi-day ordeal, trying to understand why this new system, which is much more powerful than my old one, was experiencing dropouts when it was using only a fraction of it's processing power.

I ran across this thread about issues with Nvidia and took the suggestion to roll back the driver. That did not help either. But what I did notice is that if I minimized Cubase, so I couldn't see any part of it on the desktop but it was still running, with audio coming from the speakers... I had NO dropouts. It was only when Cubase was on screen, when the graphics were being rendered and displayed, that the dropouts occurred.

So I uninstalled all the drivers for the GT730 and physically removed the card from my system. I hooked my screens to the onboard Intel graphics and... no dropouts. Only when I started opening Chrome windows and playing around on the internet did I start to get interruptions in the audio.

I then installed my old Radeon 6670 card, loaded the drivers, and I'm again experiencing no dropouts, not even when surfing the web, running FB, downloading and uploading files (at the same time), and chatting on IM. This is at 96kHz/24bit with the lowest latency my audio interfaces support (64s).

I don't know why but it appears that Cubase 8 has issues with Nvidia. I would recommend using Radeon cards or if you don't need a lot of GPU power for games and such, just using the graphics on your motherboard.

Wow, news and nobody told me... just been in touch with nVidia:

"Hello Andrew,
There is a new selection under Program Settings that is listed in the NVIDIA Control Panel under Manage 3D settings.

They should select "Steinberg Cubase" for their Program Settings.

They need to install the latest driver in order to see this new profile.

Click on the link below for Windows 7 64 driver version 355.85:
http://www.nvidia.com/download/driverRe ... 1371/en-us
"

Hope this helps you, I will try myself...

What really, Nvidia have a Steinberg Cubase setting in their control panel?

EDIT: Yes I see that list now. Didn't even know it was there. I've not upgrade yet so Steinberg isn't in that list.

I'd previously only looked at this screen default, the global settings tab, never clicking the program settings tab. I guess if I was a gamer I'd of known about this window. Huge list of settings for different games.

Yes weird I know.
The latest driver seems fine so far but I haven't used it in old freezing sessions yet.

Please Steinberg, I make a living using cubase 7.5 and its hard to charge people for a professional environment when your software drops out from time to time. Please fix!!!

Using the FREEZE button ( * ) on processor heavy tracks really took a load of of my projects.... That helped immensely.

If you havent used the Freeze function yet try it out...On Heavy Midi Instrument tracks or the rack module itself as well as plug in heavy audio tracks ( Once you are content with that track of course) You can always go back and turn freeze off too if you need to tweek etc.... BIG HELPER !

I have posted a new thread as I don't use NVidia drivers but have this problem.

I have same issue on Nuendo 4 win 7 and win 10. It works fine untill I insert some waves 9 plugins. If I disable all ins and outs and just keep one stereo out spikes disappear.

hello people,

I had this problem and drove me crazy but it happened to be the network card.

After removing the card everything perfect.
Hope it helps!

Hey guys, I know im a little late hah, but i've figured out my own little fix for this. Figuring out that this was related to my Nvidia drivers, instead of downgrading or uninstalling my drivers like alot of people did, I thought it would be alot easier to just disable any use of my Nvidia Card within cubase so that it would only use my CPU. What I did was,

1. Go to Nvidia Control Panel
2. Go to "Manage 3D Settings" Then "Program Settings".
3.If you dont already have cubase there, click on "add" and select cubase from the menu.
4. Scroll down in the options until you find "CUDA - GPUs"
5. Choose "use these GPUs" and untick everything there.

This officially disables any use of your Nvidia GPUs within Cubase, and it completely got rid of any CPU spikes for me. Hope this helps ;)

Note that Cubase 9.5 handles graphics differently, so some of the proposed fixes posted in this thread may have become unnecessary over time.
