Far Cry 2's performance is amazing! The "Dunia" engine is a work of art. It can be maxed out using a single enthusiast-level GPU.
The performance running on the machine was fine, it was the game content that sucked.
What I did not like about Farcry2 was the malaria and having to basically put the game progress on hold until you acquired more pills, the weapons jamming at the worst possible moment, and repeatedly missions ending up being on the far side of the map and sometimes the reward just as far to get back to. The size of the playing field really wasn't that big if you compare it to the original FarCry, but after you go back and forth across it about 30 times, it at least seems huge.
I played through the game a couple of times and then figured out how to really make it interesting, just go into one of the neutral territory towns, and blow someone away and then see if you can last until all the bad guys are dead.
That's like walking up to a hornets nest and kicking it, try it.
