True. This is why any serious game running on a VM with GC would avoid any kind of per-frame memory allocation and use arena allocators instead.
The whole premise of a GC to save you from thinking about memory allocation is moot if it comes to real-time sensitive tasks, there it makes things harder instead of easier. A reference counting system is much better IMO, even though you may be able to get higher absolute throughput with GC, at least the small overhead you incur is stable and predictable.
