What is the best Cell size for Phathifinding?

Hello! I'm developing a game, and my pathfinding is almost unusable and I don't use obstacles, what value can I set to make the game have more FPS and less CPU usage?

If you don't have obstacles, you don't need pathfinding. You can try tween, moveto, or bullet instead.

If you do need pathfinding for some reason, then more information about your game would be needed to help troubleshoot.

For starters, use as large a cell size as you can that still works. And make sure you're not finding a path every tick, it should only be done once until needed again.
