    Does GMS2 have HashSet data structure?

    Does GMS2 have support for hash sets? I wanted to use it, but couldn't find any. Then searched the docs and there seems to be any mention of sets in general. Though it is quite a fundamental data structure, so I'm probably missing something.

    Disabling Garbage Collector: What are the risks?

    As we know, we now have the Garbage Collector, the only problem is that it uses 14% of the CPU with only 2 loops (and some other simple layer functions) in an empty project on a Ryzen 5 CPU. When disabled using gc_enable(false), the performance drastically increases, using between 0 and 1% of...
