If you look around configuration REDEngine configuration files in PC version of Witcher 3, there is file with what for me looks like tuning parameters of Boehm-like conservative tracing GC, it is probably the only file in there that even includes comments about what the parameters mean and partially how they were determined. My overall impression from the various configuration files is that the whole world streaming/demand-paging mechanism is somehow interwoven with or even partially driven by the GC (so the GC is not meant for some small-ish scripting heap)
