Change the OS IDchange for the desired frame-rate. The higher the value, the faster the project will update the movement of all the clones and sprites using @CloneID, but the lower your computer's FPS will be.
I had to change things around a bit so it works exactly the way you've intended it to be. Once a clone is created, the @cloneID that was assigned to it and the OS totalID is permanent, so the clone can't be removed later in the project, only hidden, shown, or reused. Sprites or clones that don't move at all and are not being updated in any form won't affect the FPS counter or cause lag. The FPS counter in the bottom-left of the screen spikes into the thousands and above when the app icons are not being updated anymore.
