There does not seem to be problems with optimization as it is with Unity. But there are widespread issues with game freezing on launch or crashing during the beginning of the game. It appears to be some issue with uplay handling controllers (as it apparently was with Black Flag too). There are fixes for that, but it does not help everyone (myself included). Its amazing something like that could go through testing and hasn’t been dealth with.
Never had those kinds of issues and I'm rolling with my 360 controller right now. Not sure if having the recent Nvidia driver update meant something significant in reducing issues though
I looked online to see if there was anything egregious going on with the PC version and didn't see many serious complaints so I picked this up. Seems like a decent port in line with what Far Cry 3 was. It's running at a steady 60 for me with occasional drops to 55 or so and I have it maxed out except for AA at 1440p. Running this on an i7/980
These are Steam screenshots so you're going to have to ignore the compression but the game has a crisp look and is pretty much a slightly better looking Far Cry 3 which isn't too bad because FC3 looked pretty awesome on PC too.
Feel free to share your own impressions of the PC version. I hear that there are some bugs in the game but I'm not far enough in yet to notice anything too crazy
