"Overhead" is a term with many definitions.

Non-conservative GCs use a lot of extra metadata to be able to figure out what's a pointer and what isn't. Conserative GCs leak.

In both cases GCs cut into worse case latency.

Yes, but usually the leak is bounded [0], although I'm not aware they evaluated real-world gaming engines. But I guess frame jitter is the bigger problem there.
