Game lags when exported, doesn't lag in IDE builds

[Gamerev147]

With my game, when I test in in Game Maker Studio, there is no problem at all. The game runs at a solid 60 FPS no spikes or anything. I even ran it in developer mode, and saw no aspect of the game taking up the CPU like crazy.

When I export the game, however, I lag like crazy! I get around 20 FPS average. Why is this the case?
Here are some things I've done to reduce the lag as much as I could:

• Created texture groups for my tiles
• Made all sounds lower quality
• Removed any unnecessary objects in all rooms
• Added graphics options to turn off blood and particles
• Checked other websites and the manual on this problem

Nothing seems to fix the lag I am receiving with my exported game. Please help ASAP!

Are you using vsync? If so, go to global game setting -> windows -> graphics and check Alternate synchronization method.That helped in my game.
Otherwise cant really help without seeing your project.

you could do a lot of smaller maps and clip them together with transitions.

How could I achieve this?

Sounds the same as this: https://forum.yoyogames.com/index.php?threads/game-works-worse-when-standalone-exe.1729/

(which was solved by changing the Sleep Margin setting, which is related to vsync)
