Back during the Intel Architecture Day event in December, Intel confirmed that finally with Icelake "Gen 11" graphics there is Adaptive-Sync support after talking about it for several years. While they didn't explicitly mention Linux support, they've been largely spot on for years with supporting new display features on Linux and this should be the case as well with Adaptive-Sync and their next-generation graphics.

While disabling Windows Defender or other anti-virus programs may partially help offset the performance losses imposed by running Windows Subsystem for Linux, a.k.a. "Bash for Windows" or Ubuntu and other distributions running natively atop Windows 10 and now Windows Server 2019, it's not the root cause of the I/O performance bottleneck and is not a recommended course of action.

When setting various debug options for the RadeonSI Gallium3D driver -- like enabling its NIR back-end among many other options -- that has traditionally been done through the R600_DEBUG= environment variable. But that variable name makes little sense these days since RadeonSI doesn't even support the now-vintage R600 GPUs. Thankfully, AMD_DEBUG= is now a supported alternative.
