It should be suitable - but whether it is depends also on your memory usage. GCs are not black boxes which magically work or not work. They do get bad reputation by people who do heap allocations without thinking about them. They key to good GC performance is about the allocation profile. GO gives you very good control about heap allocation, so it should be possible to arrange the main game loop such that no fresh heap is allocated, which also would mean that the GC does not run. The GO GC runs when, the allocated heap grow to a set multiple (by default 2x) of the heap size after the last GC run. Adjusting this factor to your memory usage should give you pretty good control when the GC runs and when not.
