For applied tech Press Space! The FPS (lag level) variable tells you how many HZ Scratch requires to update the movements of all the clones. Beware, the lag gets stronger every 10 or so seconds. Scratch will start delagging after 27 seconds, so don’t expect to get higher after awhile unless you installed Scratch extensions or have a powerful computer.
Only powerful computers can get very high lag levels. If you get the world high, tell me what device you are on and you will get a shout out. Current Highest: 198789390 by @Isaac-123_2014 on an iMac w/ M3 chip
