Valve's GameNetworkingSockets 1.3 Released With Better Performance
GameNetworkingSockets 1.3 was released on Sunday as the newest feature release. Notable with GameNetworkingSockets 1.3 is better performance thanks to a new fine-grained locking strategy to reduce locking contention. GameNetworkingSockets previously suffered from major locking contention issues that hampered its scalability especially across multiple threads. This long-standing issue with GameNetworkingSockets should now be addressed.
GameNetworkingSockets 1.3 also adds an ISteamNetworkingMessages interface, header files are compatible with the Steamworks SDK headers, and various bug fixes and other minor improvements.
