Regardless of Microsoft’s claims that “should you’re a gamer, Home windows 11 (opens in new tab) was made for you” you have to to be careful for future prebuilt PCs with the brand new OS manufacturing unit put in. That is as a result of the Huge M is enabling extra security measures in PCs by default, and one specifically can severely tank gaming efficiency.
In our testing, that may add as much as as a lot as a 28% drop in common body charges. And also you thought the TPM 2.0 restrictions had been a ache…
That kind of body price delta is like dropping down a complete tier of graphics card and, in as of late the place GPUs are so onerous to come back by, Microsoft gimping the efficiency of the chip in your newbuild machine would certainly be onerous for avid gamers to abdomen.
The difficulty is Virtualization-Primarily based Safety (VBS), a setting launched into Home windows 10 which makes use of {hardware} and software program virtualisation to reinforce the safety of your system. It principally creates an remoted subsystem that helps forestall malware from screwing your PC.
Microsoft explains (opens in new tab) it as follows: “VBS makes use of {hardware} virtualization options to create and isolate a safe area of reminiscence from the traditional working system. Home windows can use this ‘digital safe mode’ to host quite a few safety options, offering them with enormously elevated safety from vulnerabilities within the working system, and stopping the usage of malicious exploits which try and defeat protections.”
It is a characteristic primarily supposed for enterprise prospects to have the ability to lock down the company PCs they drop into their workplaces and ensure they do not get compromised.
And should you’re upgrading from Home windows 10 to Home windows 11 then you do not have to fret about VBS being enabled, until you had been already working an enterprise model of the older OS, that’s. The difficulty comes should you’re receiving a machine which has had an OEM construct of Home windows 11 put in on it.
In a put up from late August, the one which reintroduced the PC Well being Test app for Home windows 11 Insiders, Microsoft once more talks up the improved security measures of the brand new OS.
I count on you already know concerning the necessities for the Trusted Platform Module (TPM 2.0) (opens in new tab), however this put up additionally talks about VBS, and the corporate’s want match the Division of Protection and its calls for for Virtualization-Primarily based Safety enabled as normal.
“Whereas we aren’t requiring VBS when upgrading to Home windows 11,” explains the put up (opens in new tab), “we imagine the safety advantages it provides are so vital that we wished the minimal system necessities to make sure that each PC working Home windows 11 can meet the identical safety the DoD depends on.
“In partnership with our OEM and silicon companions, we will likely be enabling VBS and HVCI on most new PCs over this subsequent yr. And we’ll proceed to hunt alternatives to increase VBS throughout extra methods over time.”

We have examined a number of video games on the present launch construct of Home windows 11, with VBS off and VBS enabled (although not really working) and the influence is apparent.
Far Cry New Daybreak is the outlier right here, which barely shrugs at VBS, with only a 5% discount in body price. However Horizon Zero Daybreak drops by some 25%, Metro Exodus by 24%, and Shadow of the Tomb Raider by 28%. Apparently, the 3DMark Time Spy rating solely dropped by 10%.
Why is that attention-grabbing? As a result of it was really UL who introduced this challenge to our consideration. When it up to date us about Home windows 11 assist being baked into its full benchmarking suite of merchandise, it made notice about this performance-damaging safety characteristic. And that is after I began benchmarking.
“In our testing with pre-release builds of Home windows 11,” UL tells us, “a characteristic referred to as Virtualization-based Safety (VBS) causes efficiency to drop. VBS is enabled by default after a clear set up of Home windows 11, however not when upgrading from Home windows 10. This implies the identical system can get totally different benchmark scores relying on how Home windows 11 was put in and whether or not VBS is enabled or not.
“We plan so as to add VBS detection to our benchmarks in a future replace that will help you evaluate scores pretty.”
The enablement of VBS is not having an influence on the precise velocity of the {hardware} within the system, nonetheless. We have dug into what’s taking place over a number of benchmark runs of Metro Exodus and the CPU or graphics card aren’t slowing down. The common frequency of the GPU and CPU really barely modifications.
What we now have seen, nonetheless, is that the facility draw has dropped for each processor and graphics card. However the cause for the efficiency drop is unquestionably coming from some other place.
The factor to notice, although, is that VBS just isn’t enabled by default for all clear installs of Home windows 11. I downloaded the newest ISO model of the OS in an effort to test VBS out on our check rig, however needed to do some registry enhancing, and BIOS tweaking, in an effort to really allow it. So, it is nothing to be involved about should you’re simply grabbing a Home windows 11 obtain for a recent set up your self.
However Home windows 11 PCs, constructed by the largest OEMs, equivalent to Dell, HP, and Lenovo, are wanting prone to include VBS as normal. What we’re not clear about, nonetheless, is whether or not these firms’ gaming manufacturers may also have VBS enabled. Or whether or not system builders will likely be exempt and may proceed to ship gaming PCs with out VBS.
My intuition says that gaming-focused manufacturers ought to have the ability to circumvent any Microsoft request to have VBS on by default, however these are attention-grabbing instances… You possibly can rapidly test whether or not it’s on or off your self by hitting the ‘Win’ key and typing ‘MSInfo32’, then down on the backside of the system report it is going to present whether or not VBS is enabled.
Although it’d take some registry work to disable should you do uncover it lurking there.
We have reached out to Microsoft and sure OEMs for clarification about Home windows 11 and VBS, and can replace if we hear something concrete from them. However one factor’s for certain, this safety characteristic just isn’t making me really feel safe concerning the gaming efficiency of tomorrow’s PCs.
