Game running extreme slow over time

[Reid_Dead]

I have a project that I am using as a learning experience, it was running well on gamemaker 1.4, I am redoing it on gms2.3 +, not converting, redoing it. Replacing functions that are no longer supported.
However, the game flows well in the menus and at the beginning of the first stage, from then on to each interaction the game is getting slower and slower to the point of being unplayable.

I checked the instances destroy events, number of instances and etc

Running debugger, the game has no memory leak


Game is using ~55Mb of ram on menus, fps is high



Beginning of the first stage, the memory and fps stay the same
The numbers on output is delta_time


less than 30 seconds later the game is unplayable

The "same game" running on the same PC on game maker 1.4 is running smoothly.

Someone has any idea of what's going on?

Sorry for my bad english, is not my first language.

Try running the game in debug mode, then using the "Profiler" - it should tell you what uses the most CPU power, and then you can investigate it more closely. (Start profiling when the game starts to lag and then keep it running for a while to collect as much relevant data as possible.)

Turn on show_debug_overlay() also and keep an eye on the numbers.
