It wasn't clear to me if that was something they needed to update, or if it's still valid - ReactiveCircus/android-emulator-runner#419

Relevant discussion on https://issuetracker.google.com/issues/287312019

What's confusing me is that the reply to this comment (yours?) from that issue says to use swiftshader_indirect, but the docs seem to indicate that host will perform the best if hardware acceleration is available.

swiftshader_indirect: Use a Quick Boot-compatible variant of SwiftShader to render graphics using software acceleration. This option is a good alternative to host mode if your computer can't use hardware acceleration.

Maybe worth a reply on that issue?
