This BIOS Setting is Ruining Your PC – SVM Virtualization On vs Off
Okay, so you want more FPS in your games and the latest and greatest CPUs just aren’t cutting it while I got great news for you because a new setting in Windows 11 appears to be absolutely destroying performance and that setting is virtualization. Now as a disclaimer, I don’t necessarily recommend disabling it officially as it can put you at greater risk security wise, but doing so did net me some massive performance gains. Now one way of disabling it is to turn off core isolation in Windows, but for maximum effect I found its best to disable SVM on AMD systems in the BIOS or virtualization on Intel systems in their BIOS. And from what I’m hearing, AMD might actually benefit more than Intel. I can’t necessarily confirm that, but even on an Intel 14700K system I’ll be testing today, I found some pretty significant differences, which by the way, here are the rest of the system specs, but in any case, let me show you just how drastic it can be across nine different games.

  1. this old thing still coming back? i thought this was supposed to be new… im keeping virtualisation on thanks. i dont want a virus able to install so deep in windows kernel it cant be removed or gets access to the bios.

  2. Tech-tubers should include benchmarks for these settings on upcoming cpu's from now on (along with the usual benchmarks).

    It might be interesting to see what AMD and Intel can do to lower the performance-impact on future generations.

  3. As a rule, CPU bound games are seeing gains with this setting turned off. So, if you're not seeing any changes in Black Myth it's because that one heavily GPU bound even with a 4090.

  4. NO, If you use virtualbox, bluestack and any other emulators that require VT you will cripple your performance, its a NON issue on WIndows 10, the real issue its WIndows 11 running like crap full bugs, and now with even more AI spywares recall enable even when you dont have a NPU.

  5. You know that by deliberately testing at 720P you would produce results that nobody who plays games will every see. Again, no games are "going to feel a whole lot less choppy on a 4070 super as nobody bought that graphic card to play at 720p. The last mistake you made is saying "You will likely see a more substantial improvement than buying and entire new platform" but you deliberately never showed us the variance in FPS at 1080P, 1440P & 4K that people actually play games at, so what is the variance at these resolutions? Its not like it would have been a lot more effort to change that resolution and run the benchmark again. Sorry but you lose my respect for being deliberately deceptive for clicks.

  6. Virtualisation doesn't have any bounds with core isolation. It's a 2 different features with different specialization.
    Core isolation DOES have performance issues.
    Virtualisation DOES NOT have SIGNIFICANT performance issues like you're talking about. 1-2% loss? Maybe, but not more than this. Don't be a liar pls.

  7. Why would you disable SVM/VT-x entirely instead of just core isolation… or even test with those off vs. no core isolation…… now nothing can use virtualization. This channel is going to give me a conniption as a sysadmin lol

  8. thanks for this turned mine off and all Stutters went fully away in Black Myth Wukong on High with a RX 7600 (8GB) and a 3700X with 32gb's CL18 3600MT/s Ram so glad to have it off

    edit: didn't matter what settings I used high, medium, low etc all had massive stutters especially for specific cutscenes wish I could have got these results for my first playthrough but on second now and enjoying it after the change.
