What is Gw2-64.exe?

Guild Wars 2 is a high-fidelity, online multiplayer role-playing game developed by ArenaNet and published by NCSOFT. The game client (Gw2-64.exe) runs the core MMORPG experience: it renders environments, processes actions, manages network communication with the GW2 servers, and coordinates updates and patches from the launcher.

Gw2-64.exe is the main 64-bit game client executable. It runs as a single process with multiple threads handling rendering, input, physics, and network I/O, while updates are managed by the launcher. The client relies on DirectX/Vulkan for graphics output.
