WGAF is the game engine developed by Guild Software which powers their MMORPG Vendetta Online. It runs on Linux, Microsoft Windows and Mac OS X. It has also been known to run on various BSD Descendants. An example screenshot from Vendetta Online can be seen at right.

[edit] Technology

WGAF uses several methods including dynamic level of detail (LOD) to ensure performance across a wide range of systems. It also uses vertex and pixel shaders to generate sophisticated lighting effects. However, one should note that WGAF does not actually support dynamic lighting or shadowing.

WGAF also has unique network code. All data is sent over UDP instead of TCP, allowing for packets to arrive out-of-sequence (which is sanity-checked by the client). Vendetta Online, and therefore WGAF, uses very little bandwidth (literally in the bits per second range), and generally can give users pings in the 40-200ms range, depending on the user's physical location. Players from areas as far as Washington, D.C can get pings of about 65 ms on average, using a DSL connection. (1.5 MB)
