What is turbo mode?

I know you activate it by pressing shift while clicking the green flag, but what changes does it make to your project?

What is turbo mode?

Hi

In turbo speed, all scripts run at extreme speed. This is very useful for speeding up mathematical projects, however makes features such as graphic effects and clicking on sprites lag quite a bit.

It changes nothing about the project, all it does is make the project run faster.

I think it comes down to screen refresh rate being faster in turbo mode. I'm pretty certain it's that.

It still refreshes the screen 30 times per second the difference is that in turbo mode scratch no longer waits for each screen refresh. So
when green flag clicked
repeat (30)
move (1) steps
end
will move a sprite 30 steps in one second and you will see the sprite move smoothly as scratch waits for each screen refresh on each iteration of the loop and 30 x 1/30 = 1 second.

In Turbo mode scratch won't wait, so the script will run as fast as your computer will go and the sprite will effectively teleport 30 steps. You can achieve the same thing using a custom block and setting the run without screen refresh option, so Turbo mode is not really needed.

10 !
ScratchVaders or Galaga?
Maybe Eliza can help you decide?

Yep, that sounds spot on!

Turbo mode speeds up the project(sometimes making it smoother).
define 
move ((3) * (2)) steps

Everyone repeat after me

As well as speeding up scripts and projects considerably, it can work as a sort of “Debug Mode” to eliminate
glitches and that sort of thing. However it does sometimes create glitches, for example, try @JamesO_O 's platformer “Sir Shield” in turbo mode,
it is really glitchy!

Since this topic hasn't seen a new post from the topic owner in a long time, I'm going to assume that it is dead and close the topic. If it still is alive, the topic owner just needs to use the Report button to ask a mod to reopen it
