I hope they don't use naive reference counting. It would reduce throughput and would not eliminate pauses. A standard incremental or concurrent generational tracing GC would be a better choice. In games you have a lot of knowledge about timing that you can use to help schedule GC: you always know (or should know anyway) how much time there is until the next VBLANK, so you can use that to bound pause times for your major collections.
