Hi everyone. Been trying to fix this for 2 weeks now. Did an upgrade on my tower PC computer and now all of my Cubase demos are glitching, sporadically glitchy. I’ve turned the buffer rate WAY up, but that’s a band-aid for a broken arm as it makes recording problematic.
Anybody out there who can help get rid of these glitches? Thank you.
Hi and welcome to the forum!
Can you give us more details about your system?
OS, CPU, RAM, graphic card, audiointerface … the usual suspects.
If you use an NVIDIA graphic card make sure to install the Studio Driver and not the Suite. This has caused all sorts of issues in the past. Also make sure to update your audiointerface’s driver and firmware, please.
What @Reco29 said, and what was the upgrade?
I “demos” may have a different meaning to different people. Do you mean Projects?
Here you are Reco29- thank you.
Windows 11, 12th Gen Intel (R) Core™ i9-12900KF, 32 GB RAM, NVIDIA Quadro NVS 295, Focusrite Scarlett 18i20 2nd gen
The upgrade was made by my local computer guy so I have no idea if when installed he installed the Studio Driver and not the suite. Any idea if that can be found somewhere within my computer specs?
Thanks for your help and ideas for getting rid of these glitches.
Yes, projects.
So your " local computer guy" did the upgrade. What did he upgrade?
Was Cubase working fine before the upgrade?
Also, the NVIDIA Quadro NVS 295 is positively antediluvian (2009?), the Intel graphics will probably perform better. (I’m with Win 10, so I don’t know how to change this in Win 11. In the Display/Graphics settings, somewhere.)
Absolutly - this will most likely be the culprit!
I’m afraid your graphic card will not be enough to support Cubase 12 on a Windows 11 system. Have a look at the specs - it doesn’t even support Windows 11 or DirectX 12:
Please, follow @Googly_Smythe 's advice and try the onboard graphic card instead 
Here’s a step by step tutorial in case you want to give it a try with your current graphic card and the NVIDIA Studio driver:
I certainly appreciate the feedback, but the gentleman I am working with had me backup my Cubase files then uninstalled and then reinstalled Cubase. The glitches only slightly diminished.
He is suggesting that the next move be to uninstall the NVIDIA driver then physically remove the GPU. Have not done that just yet.
Thoughts to that anyone? Thank you.
Please, read the advice that has already been given to you above…
Uninstalling and reinstalling Cubase would not have made it on my priority list 
Please, try these two things, the order doesn’t matter:
-completely disable the NVIDIA graphic card in your system settings and enable the Intel onboard graphic unit > any change?
-follow the instruction above to remove the old NVIDIA driver and install the NVDIA Studio driver > any change?
In case none of these steps help a new graphic card would most probably be the next move.
Good luck!
Unfortunately, it looks like the i9-12900KF doesn’t have integrated graphics at all.
Drew22: If using the Nvidia Studio driver doesn’t help, then you’re going to need to try an entirely different graphics card all together. Any decent budget GPU will do, and if you were sticking with that Quadro because it’s fanless, you’ll be happy to know you don’t have to worry much about idle GPU fan noise these days. Unless you’re gaming or running GPU hungry software, it should be virtually silent.
Hi Midee. Thankyou for the reply. Not being an engineer at all, I’m not sure what you mean when you say “Unfortunately, it looks like the i9-12900KF doesn’t have integrated graphics at all.” COuld you elaborate please?
Also, I have yet to try the above recommendations as I have been inundated with work. Do you have any other suggestions to eliminate the glitches besides the recent recommendations? Thank you.
Hello anyone and everyone,
I’ve spent hours trying numerous ways to solve the problems by :
"-completely disable the NVIDIA graphic card in your system settings and enable the Intel onboard graphic unit > any change?
-follow the instruction above to remove the old NVIDIA driver and install the NVDIA Studio driver > any change?"
HOWEVER, the steps to get there are not seamlessly smooth at all as there are a number of different “options” to potentially solve the problem on the way TO potentially solving it.
I’m now on my full 2nd month of dealing with this. Is there ANYONE out there willing to help one on one, (Zoom, FaceTime, etc)?
Thanks
Drew
My computer guy just installed a ASUS Dual NVIDIA GeForce RTX 3050 6GB OC Edition Gaming Graphics Card - PCIe 4.0, 6GB GDDR6 Memory, HDMI 2.1, DisplayPort 1.4a, 2-Slot Design, Axial-tech Fan Design, 0dB Technology, Steel Bracket.
THE GLITCHES REMAIN.
ANYBODY have any solutions?
Hi @Drew22 ,
an updated graphic card was definetly a good investment!
How did you uninstall the NVIDIA driver suite and how did you install the NVIDIA Studio driver afterwards? Can you provide details, please?
Also, can you download and run LatencyMon in idle mode, please? Maybe there’s something wrong someplace else so we should have a look at other things, too.
The suggestions regarding the uninstall/reinstall were great but it was not a clear path and afterwards I could hear nothing, do I uninstalled what I might have done.
Will look into LatencyMon. Thank you as always, Reco29!
