I have i7-12700K/RTX 4070STi and VMWare 17.6.3 on Win11 24H2 in CPL0 mode. Since I had an issue with Vulkan/DX12 + Win10 VM, I disabled it and now everything is smooth as it was on v15. I tried the same trick for old bare-metal converted VM with Win7 SP1 (VMTools 12.5.1) and Aero was completly unusable. 

Why the same trick doesn't apply for legacy OS?

.vmx:

mks.enableDX12Presentation = "FALSE"
mks.dx11.allowUnsupportedDevices = "TRUE"
mks.enableVulkanRenderer = "FALSE"
mks.enableDX12Renderer = "FALSE"

PS Is there extensive documentation explaining config I added, mks.enableDX12Presentation vs mks.enableDX12Renderer for example ?
