This extension optimizes server performance. This allows the game to be run on any remotely modern cpu (2 ghz sandy bridge cpu is now enough to host 32 slot server).

The performance gains are even greater when using high snapshot rate SourceTV (As the extension negates most of its impact on frame time)
Memory usage when using SourceTV is also reduced

Games other than TF2 and CS:S (But not CS:GO and some others) are partially supported.

Some of those convars are TF2 only
