Virtualization Based Security (VBS) has a big impact on frame rates
VBS is enabled by default in Windows 10.

Remember back when Windows 11 launched and there was a concern about how the default of enabling Virtualization Based Security (VBS) and HyperVisor-Enforced Code Integrity (HVCI) might impact performance? There was a lot of noise made, benchmarks were run… and then we all moved on. Flash forward to 2023, and I recently discovered that sometime in the past few months, the PC I use for the GPU benchmarks hierarchy received an update that turned VBS back on.

Windows 10 also has this setting and it may also be enabled by default now..

Windows VBS: The Bottom Line

So, should you leave VBS on or turn it off? It’s not quite that clear cut of a question and answer. The actual security benefits, particularly for a home desktop that doesn’t go anywhere, are probably minimal. And if you’re serious about squeezing every last bit of performance out of your hardware — via improved cooling, overclocking, and buying more expensive hardware — losing 5% just to some obscure “security benefits” probably isn’t worth doing, so disable VBS…

Yeah, well it’s not enabled on my machine and it doesn’t look like it will be!

That’s one long list of drivers that I’m not going to play with since the machine is running just fine.

FYI: I used the PowerToys Text extractor to grab that list and then just edited it. Sure saves a lot of time and typing errors!

Don’t know why it shows up twice but it does. I may try to fix this one

I’m going to assume my Test Dell Win 10 Pro circa 2013 has just as many problems as my daily driver!

Per MS:

Turning on the Memory integrity setting would block these incompatible drivers from loading. Because blocking these drivers might cause unwanted or unexpected behaviors, the Memory integrity setting is turned off to allow these drivers to load.

If you want to restore the Memory integrity setting, you can try to resolve a driver incompatibility by seeing if an updated and compatible driver is available through Windows Update or from the driver manufacturer. Microsoft does not recommend that you delete drivers to attempt to restore this setting.
