I've tried various browsers and MC always stutters using browsers especially. I assume processor is taking away from MC. I tried increasing MC priority to high but doesnt seem to solve the issue.
Anything I can do to prevent stuttering?

Web browsers in MC are an external component (e.g. Edge via WebView2 which is the current default on Windows). Perhaps something like an antivirus app or some other app is doing something to cause issues with it?

It happens specifically when I launch web browsers and open tabs

What processor, sample rates, number of channels, and are you using any dsp?

[Awesome Donkey]

Oh, you mean it happens when using an actual web browser, not when using the embedded browser in MC itself. I've seen this happen on Windows on a lower performing system when Windows Defender's memory integrity feature was enabled. This uses virtualization technology which can interfere with audio playback in MC and cause stutter issues on lower powered systems for example. You can try increasing the buffer for the audio output used and see if that makes a difference, but the case I experienced years ago I ended up having to disable memory integrity in Windows Defender's settings in order to resolve it.

If memory integrity isn't enabled, then it kinda sounds like spikes in DPC latency. In that case try using an app like LatencyMon and see if DPC latency spikes are happening. Like whoareyou mentioned it's probably a good idea to list system specs.

It's i7 so not low end ... regarding latency, honestly I'm not that techie and wouldn't know what to look for or do about it in LatencyMon

LatencyMon will tell you if DPC latency spikes are happening and what a basic culprit of it may be. Something's definitely happening on your system though, as it shouldn't happen with a system with that much RAM and a newer CPU like that. It's hard to say what exactly is causing it, I would put my money on a driver or something causing DPC latency spikes or memory integrity being enabled and causing issues but I could be wrong with those guesses.

Thanks for your help ... I installed LatencyMon ... initially it said for me to check contol panel for CPU throttling cause of a audio issue. I had it on "balanced", so I changed it to high performance and it definitely improved, however still a slight issue but definitely less than before. It mentioned something about bios but not sure if I want to mess with that ... would bios setting on any CPU throttling be any different that that in Control panel Power settings?

Strangely I got this screenshot after making power "high performance"

Antivirus?

Or something else running in the background.
