I've been tinkering a bit with the engine, upgrading some components, and decided to backport the changes to Dead Hand. Changelog follows:
Full Patch Notes
Switched from the venerable DirectSound API to XAudio2,
upping the minimum requirements to Windows 10 as a result(can't do that yet, still have players on Windows 7).Replaced the Lua 5.2 interpreter with LuaJIT, improving performance on low-end CPUs.
Updated RecastNavigation library to the latest version.
Pathfinding improvements.
More robust actor snapping to ground algo.
As usual, fixed a bunch of minor bugs and memory leaks.
Have fun!
