Interesting video. I often wondered if there was any performance gain from turning off BitLocker, but not disabling VBS. On a Surface Pro 9 & 10 I can see the merits of having BitLocker enabled, as you can readily upgrade the SSD via a service door under the kick stand. From the demonstrated performance gains, I would be inclined to leave them both enabled.

Nice I have mini os installed and it's even better than this but this is great if you don't to go through that

Thanks for the video. I was interested which impact this will have on the Surface for gaming. The mentioned "bcdedit /set hypervisorlaunchtype off" completely disables the hypervisor without the need to change all that options before.

Bitlocker is just the GUI of the security controller on SSD & NVME. Since encryption and decryption are handled in hardware by the controller, you shouldn't see much of a difference in game performance even if DirectStorage is active. Based on Ancient Gameplay's recent video, the biggest contributor to slowdown is Core Isolation. Switching that off in Windows Defender gives a huge performance boost for most programs and games. I'm not sure how VBS work to comment. But I run a Hypervisor for my main PC and ROG X13 Flow 2022 to allow another instance of Windows to run into my current Windows and even on my ROG X13, everything runs well.

Addition to my comment (which is not visible, maybe because of a link posted): In general Bitlocker can use hardware encryption. The automatically activated version does not and slows down the drive a lot.

@@cvzone yes I know all about storage encryption in the past. Used TrueCrypt on a laptop running Core Duo and HDD due to work requirements. When I upgraded to SSD, I made sure it supported Self-encryption (SED). My experience with Bitlocker was the same, if SED is in the controller, Bitlocker turns on instantly. No need to encrypt or decrypt and no progress bar. I suppose the SSD/NVME that slowed down has controller that don't support self-encryption. I thought that it's a standard features for ALL SSD/NVME controllers these days. It also seem like with Windows 11, Device Encryption is the hardware SED and Bitlocker is now software based. Think I've forgotten about this for Win11.
