I am using the version 3 of MIT-Scratch to create a simple game. It's running smooth in the (smaller) editor view, but it hast quite significant lag (only a few fps) in the full screen mode, on the same machine. It's an older DELL machine.

Why is there such a large difference between view modes and what can I do about it?

Note: The game is very simple, just a backdrop and 2 animated sprites (no costume changes).

Note2: I tried both png and svg variants of the sprites and backdrop, but the performance does not significantly change, plus the difference is still clearly noticeable.

Note3: The overall performance differs a bit between browsers (Firefox / Chrome) and OS's (Windows 7 / Ubuntu), but the difference between edit/fullscreen is still significant.

Note4: On newer machines with more computing power (like my dev pc) this is not noticeable.

This seems to be a problem with your computer's hardware, or the memory is being over-used. On my computer, there is no difference.

To try to circumvent this, try the following:

  • Close all other tabs/windows
  • Free up hard drive space

Try https://turbowarp.org/. It compiles scratch as Javascript to make it run up to 10 times faster. Put in the project link and run. Note that it only works for shared projects.
