Culpa Innata

What works

Everything in the game works normally up to the first trip through the Metro in the storyline. No DLL override or use of Winetricks is required to install or play the game.

What does not

Fatal crash at the part of the storyline where you make your first trip through the Metro and access the game's internal PA. This prevents me from continuing the game past that point as there is no storyline way around it. EDIT: (found a workaround, detailed in later test results) There are some problems with pixel shaders which may cause a blank or monotone display. This is detailed in the HowTo.

Additional Comments

There are random in-game PA related lockups, mainly at the Inventory screen. These are present on all platforms, not just Wine. I did not require any DLL overrides or any use of Winetricks or similar methods to install or use this program. It is my recommendation to not use any such methods as they may interfere with debugging other problems.

If you have problems with a black, monotone or blank display of the game, without any lockup or crash, this is due to problems with the pixel shader implementation of Wine and the requirements of Culpa Innata. These problems do not occur for everyone.

If they do occur for you, the way I fixed it was to configure Wine with Pixel Shaders enabled, but with no support.

To do this using GUI follow these steps:

1: Open Wine Config, and select Add Application. Nagivate to your Culpa Innata install directory and select Game.exe (Culpa Innata's main executable), then press Open to add it.

2: With Game.exe highlighted in the Application list, go to the Graphics tab. This will ensure that these settings only affect Game.exe.

3: In the Direct3D section, change the "Vertex Shader Support:" selection to "None", but leave "Allow Pixel Shaders (if supported by hardware)" checked.


Please let me know if this procedure does not solve this problem for you, so that I can debug it further.
