While 2014 CppCon talk "C++ in Huge AAA Games" focused on reality for a lot of games developed at Ubisoft Montreal, this talk with focus on what was done to ship Rainbow Six Siege at 60 frames per second. Delivering a game with 5 versus 5 multi-player with heavy procedural environment destruction at 60 FPS was a constant challenge. From memory usage to lock-free solutions, a lot of developed C++ solutions are reusable outside of games. Some interesting analysis tools were also developed to find issues, and their concepts could be reused by any C++ developer caring about performance.

Good to see Ubisoft engineer contributes to better of things in the c++ standard especially std::function, I also watched Carl Cook mentions about it will allocated on heap if size is not small enough. From my research (64 bit, PC linux), such threshold size is pretty small, if you exceed 16 bytes (size equals to member function pointer), then it will allocate on heap.

On GCC/Linux, I got Segmentation Fault just by sizing an array above 100, 000. What's the maximum size for an array, afterall?
