Are you not using an x86 emulator or something? Forget to install or enable your CPU virtualization extensions?
Because the emulator ain't sluggish, and if it is you'd get that same sluggishness with WSA since it's largely the same underlying tech. It's still using a virtual machine and emulation, it's not like a simulator.
i am using an x86 emulator - booting it up takes about twice as long though compared to WSA. Also being able to dynamically resize the Window as need was nice to test different sizes directly within WSA instead of having multiple emulators running
Everything? It's a Hyper-V virtual machine hence how it can run Android's Linux kernel & HALs. It's not doing ARM emulation as well, but it's still an emulator at heart.
