Hi, thanks for your feedback!
Will make changes and update the objectives UI, as well as the ESC part.
Tested the game on two different devices, and both of them work well without having huge FPS drops issue.
May I know what is your PC specs, and on which area of the map you face the FPS drop issue? Or the FPS drop just happened randomly?

Device 2 (Laptop):
