What is your view on the "Memory Integrity" switch?

Now that "Memory Integrity" under "Core Isolation" is turned on by default in Win11, I had to turn it off in order to be able to carry on using my Roland Quad Capture (UA55) audio device. Win 11 flagged the driver as not suitable.

What is your view on the "Memory Integrity" switch? I never had this turned on on any of my Windows 10 machines, ever.
How about performance impact etc?

Only really of use for business and critical systems, the average home user probably doesn't need it to be on. I clean installed Windows 11 Pro with no 3rd party drivers and it was not on by default. I can turn it on however.
In a business environment drivers are only allowed to be installed under strict policies usually so this setting is easier to manage, home users tend not to be so fussy and enthusiasts probably wouldn't want to take the performance hit.
Depending on your use case and hardware the setting could cause drastic slowdown, best to conduct some benchmarks with it on and off to see if it is worth it for you.
