There is a growing community of game developers using Nim. But Nim doesn't have a single GC, it has multiple and the default one can be compiled with real-time latency constraints so that you can use to make sure that you don't stop the world for less than 1/200 of a second for example. Plus the GC is per type, you can mix raw pointers for manually managed memory and references for GC-managed objects. The GC can only be triggerred in code paths with references.
