It doesn't say that in the slides. It says that they use C++ *and* 
script code. The slides are also talking about Gears of War, too, not 
just Unreal.

Which just repeats what I said, "I assume by this he means that for C++ 
the developers end up writing their own garbage collector inside the 
program."

Check the slides again. It has to run at 30-60 frames per second. This 
is "soft" real-time.

Interestingly enough, under Musings he says, "Memory model: Garbage 
collection should be the only option". Real-time garbage collection that 
actually works well in a game setting would be the ideal.
