So, as you might know, there's an option in the custom block editor called “run without screen refresh” - it makes the block run as fast as possible instead of stopping to update the screen.
Anyway, not many people know what a screen refresh is when they join Scratch, and the name is not self-explanatory. Therefore, I suggest renaming it to “run instantly”
While the name is a bit misleading (it doesn't actually run instantly, try putting a forever loop to see the results), it will likely make more sense to new users than “run without screen refresh” - and “run without screen refresh” is misleading too (Scratch makes projects have a minimum of 2 frames per second.)

Sorry if this is a duplicate, I couldn't find any in the directory.

Have you asked other Scratchers — including newer programmers — which one makes more sense to them? If not, it seems like this is more of a guess than concrete evidence.

When I hear “run instantly,” I think, "Well, yeah, any code I click on will run instantly. It's not like it will take 1 second to say “meow” if I have the following script:"

define block
play sound [meow v]

when green flag clicked
block

Alright then, would “run loops instantly” be better?

it doesn't run instantly - just waits to update the screen until the end. everything still takes 1/30th second.

I believe the current name is fine—Perhaps a “(i)” next to it to open up a note about what it means.
