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:
