PCSX2 SVN r4387 is released. PCSX2 is an open source PlayStation 2 (PS2) emulator for the Microsoft Windows and Linux operating systems. With the most recent versions, many PS2 games are playable (although speed limitations have made play-to-completion tests for many games impractical), and several games are claimed to have full functionality.

PCSX2 SVN Changelog:
r4385
cmake:
* add new cpp files for GSdx
* Ensure V2 API include files of portaudio
r4386
New feature!
There's a new option in the GS window configuration that allows a "managed Vsync".
This new option will dynamically toggle Vsync based on the current frame rate.
If the game runs at full speed, it turns Vsync on. If it drops below full speed, Vsync is turned off.

This effectively allows Vsync to be enabled in most games while avoiding the huge performance penalty
it usually causes whenever the FPS drop below full speed.

Note that the feature currently only works nicely with GSdx DX10/11 HW rendering.
The other renderers and plugins will either ignore the Vsync switches or they'll show an
annoying black frame on each switch.

A few fixes for some situations I didn't consider.
