All games use mailbox/triple buffering. Except when you enable sync to host refresh, in which case FIFO/double buffering is used. This means vsync enabled will ever tear, but at the same time, never drop to 30fps on a missed frame due to frame rate differences. To have the "best of both worlds", you should enable vsync and sync to host refresh. Previously, this resulted in additional input lag, since the host vsync would drive the EE frame timing. Now, this behaviour is disabled by default, unless you enable "Use Host VSync Timing". |

PCSX2
PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. Its purpose is to emulate the PS2's hardware, using a combination of MIPS CPU Interpreters, Recompilers and a Virtual Machine which manages hardware states and PS2 system memory. This allows you to play PS2 games on your PC, with many additional features and benefits.
Project Details
PCSX2 has been in development for more than 20 years. Past versions could only run a few public domain game demos, but newer versions can run most games at full speed, including popular titles such as Final Fantasy X and Devil May Cry 3. Visit the PCSX2 compatibility list to check the latest compatibility status of games (with more than 2500 titles tested).
Installers and binaries for both stable and nightly builds are available from our website.
System Requirements
PCSX2 supports Windows, Linux, and Mac platforms. Our setup documentation page contains additional details on software and hardware requirements.
Please note that a BIOS dump from a legitimately-owned PS2 console is required to use the emulator. For more information, visit this page.
Contributing / Building
PCSX2 supports translation into other languages using Crowdin.
