For years i’ve always ended up running into issues in Cubase where once I get to the mix stage I can’t play the project without lots of freezing of tracks, and even with my basic template which has my core plugins loaded, (almost all being effects, as I only really uses hardware synths), I couldn’t play below 512 buffer without crackles. Enabling constrain delay compensation always helped when I needed to play at low buffer settings, and I could see it disabled about a dozen what must be heavier latency inducing plugins which was fine, as I could just re enable them when I was mixing, but still, it was annoying, and the issues when I was trying to mix were often a real pain, often even leading to crashes if I tried to push my system too hard.
I’ve tried tweaking my system to improve performance many a time but nothing has made much difference. My usual is:
- RME UCX @ 48khz with MMCSS for ASIO enabled
- i7 4790K OC’d @ 4.4Ghz with the usual recommended tweaks for music production like disabling speed stepping etc
- Cubase settings: Multi-processing on, Normal ASIO guard on, Stenberg Power Scheme on
- Windows tweaks like optimising processing for background services
I had accepted this issue for years and just got by assuming I must just be happening to my use of demanding plugins, but today after I had crackles on my default template at all buffer sizes I went and did some more tweaking to my usual above.
The first was enable Audio Priority in Cubase (I think i’ve tried that before though and it made no difference), and the second was changing my graphics card setting via its control panel tray icon from Graphics Profile - balanced, to Optimize Performance. (I use an aging gaming card, AMD R290)
I then double checked my BIOS settings and everything was the same as usual for my modestly OC’d CPU and with the usual audio performance tweaks in place like disabled speed stepping, but when I rebooted and started up Cubase with my template I couldn’t believe the difference!
The performance meter with nothing playing had dropped 50% and I was able to play at 96 buffer no problem whatsoever.
The key thing that I had never tried before was changing my graphics card to optimise for performance, and possibly boost on Audio Priority.
Anyway, I hope this helps someone else out.
