[gclist] Games in C++ with GC? (why malloc/free instead of GC?)
Tue, 18 Feb 2003 09:42:47 +0100
Further to this disscussion about the use of GC:
Games, espcially 3D games, are often written in C++, using DirectX (or OpenGL).
Is there any experience in using GC ()conservative or not) in such applications?
Being a sort of real time program, I can imagine GC latencies is a potential problem ...
