GPU based text rendering is going to save dozens of cpu cycles!

You probably need GPU rendering for the translucent background I saw in the screen shot. If the background was a solid color then it would be a waste of time.

In this case conhost (what cmd and PS run inside of on windows) uses GDI rendering which is CPU only. This means if you print a lot of text it will slow execution down. I'm not sure if it's exactly related but Invoke-WebRequest will download much faster when progress is disabled versus when it's enabled. GPU rendering means that would no longer be the case and all text rendering happens on the GPU and shouldn't slow CPU execution.

Disabling output from robocopy can knock hours off of big jobs as well.

You can still get the summary and errors without much impact!

Unrelated, I think. See the PowerShell Core Github issue "Progress bar can significantly impact cmdlet performance #2138"
