I think it's the real one, not sure. Tbh i've givin up on farcry now. Might try again in a few months
Well if you're not running a 64-bit OS, then you can't really use the 64-bit patch. The 32-bit is unofficial, and has both "32" and "64" in teh original filename. I would THINK that the true 64-bit patch installer would stall if one tried to install it one a 32bit OS.
Or jsut ditch that patch. Other than a bit of extra terrain in teh first couple levels, all it does is add bump-mapping to rocks and a couple other surfaces. You can get much teh same effect by installing the K9-Vision or other large texture pack.
Maybe check out the USisoft Far Cry forums, theyr'e quite helpful and sitll used frequently..
On another note, did you use teh FOV fix at http://www.widescreengamingforum.com/node/ ??
