The "Disable Core Isolation" option in the playbook breaks WSL2 and Docker. The error `Wsl/InstallDistro/Service/RegisterDistro/CreateVm/HCS/ERROR_PATH_NOT_FOUND` is a direct result of VBS being disabled, since WSL2 depends on the hypervisor stack. The option was added for performance reasons. While modern CPUs (post-2018 with MBEC support) see a smaller impact than older hardware, benchmarks still show around 5% performance loss in gaming workloads even on recent hardware like the Ryzen 5800X3D and RTX 4090 systems. Chris Titus Tech covers this in several videos and reaches the same conclusion. The tradeoff is not worth it. Disabling Core Isolation breaks WSL2, Docker Desktop, and other hypervisor-dependent tools, while the performance gain varies and is inconsistent across hardware generations. Additionally, modern Windows features and even games are increasingly dependent on these security features being enabled. There are recent games that require these security settings to be active. I know that is unfortunate, and I am not a fan of kernel-level anti-cheat either. Containerization and virtualization features break entirely, in exchange for a performance gain of around 5% depending on hardware. I think we should be more careful about recommending this to new users who run the playbook. Proposal: remove the Core Isolation disable option from the playbook. Users who want it disabled can still do so manually via the Atlas Desktop folder shortcut, or possibly via the toolbox. Relates to #1615. --- **Sources:** - [WSL2 stops working with memory integrity (Core Isolation) turned OFF - microsoft/WSL #8485](https://github.com/microsoft/WSL/issues/8485) - [Windows VBS Setting Slows Games Up to 10%, Even on RTX 4090 - Tom's Hardware (2023)](https://www.tomshardware.com/news/windows-vbs-harms-performance-rtx-4090) - [Benchmarked: Do Windows 11's Security Features Really Hobble Gaming Performance? - Tom's Hardware (2021)](https://www.tomshardware.com/news/windows-11-gaming-benchmarks-performance-vbs-hvci-security) - [Microsoft's VBS/HVCI still hurts Windows 11 performance even on latest versions - Neowin (2024)](https://www.neowin.net/news/microsofts-vbshvci-still-hurts-windows-11-performance-even-on-latest-versions/) - [VBS and HVCI Impact on Gaming Performance - Windows Forum (2024)](https://windowsforum.com/threads/windows-11-security-features-vbs-and-hvci-impact-on-gaming-performance.341039/) - [Win11 WSL2 while Core Isolation disabled - Reddit r/bashonubuntuonwindows](https://www.reddit.com/r/bashonubuntuonwindows/comments/1bps9ts/win11_wsl2_while_core_isolation_disabled/)
