The problem that occurs when playing the game on lower end PCs is that the game engine is not able to run at more than 30 FPS, which causes motion blur and slowdowns on the game's animations and other graphics. This results in scenes that seem to only be 30 FPS when played on lower end PCs, where it is actually 60 FPS. This problem is most noticeable in cutscenes as well as in some action sequences and game dialogue. The game's FMV sequences could also potentially suffer from this problem depending on the system's capabilities. The game engine only supports a frame rate of 30 FPS, so there is no way to raise the frame rate to 60 or higher, and it is unknown if the game engine will actually run at 60 FPS and simply cap it at 30. Some players report that the game still runs at 60 FPS when the game engine runs at 60 FPS, while others report that they experience problems such as occasional slowdowns. The engine will not run at 60 FPS even when the frame rate is set at 60, so it seems that the engine itself is not capable of running at 60 FPS, or it is just as likely that the game engine is missing some code that is needed to render at 60 FPS. Some players also report that the game runs at 60 FPS when using the game's resolution setting to 1200x720, which the game engine cannot seem to run at. The game engine is also incapable of rendering at higher than 720p, so that is not a viable option.
It is unknown when the port was originally released or when it was made available to the public. At some point in time, it was made available for purchase on Steam and was later removed due to the game having some issues that were not addressed. Some people report that the game still works properly on Steam, despite having fixed issues reported at Steam Support. It is unknown whether the port was made available on other channels such as GOG.com and/or Direct2Drive.com.
In March 2013, Capcom released a patch for the PlayStation 3 port that removes the 30 FPS cap. This port is included in the Resident Evil 5 digital collector's edition which is only available in the PAL region, but not the US version.
