As i see here (LINK) there are three types of patch.

Gog version is 32bit, right? So to have last version i need to setup 64bit patch, right?

Do i need to instal 64bit content pack after 64bit patch?

Found this on readme:

This Enhanced Content Patch requires the FarCry AMD64 Update patch to be installed.

1. Install the original 32 bit version of FarCry
2. Install the AMD64 Update Patch
3. Install the AMD64 Enhanced Content Patch

But i see that 64bit is 1.32 version while gog 32bit is 1.4, won't this be a problem?

The 64-bit version isn't the latest version of the game, so what you've said is correct. You can choose the latest version (1.4) or you can use the 64-bit version and not have the latest version. A little unfortunate, yes, but that's how it is. From GOG's point of view, though, not everyone has a 64-bit OS so selling the 32-bit version makes sense, and it is also fully patched.

There are alternatives though. FCAM enables some of the 64-bit features within the 32-bit game. Depends on whether you like the features FCAM brings or whether you want a vanilla experience.

Is there any good side by side compare of features that are avalable in 64 bit version?
