What works

Playing the game, saving, loading, changing most graphics settings.

What does not

Alt-tabbing results in a crash when you try to return to the game.

SMAA results in an immediate crash (seh exception) and you have to wipe graphics settings in order to successfully relaunch the game.

Soft Shadows result in occasional corruption, so just don't use them.


I installed the game through steam, which in turn installed a version of Uplay which couldn't connect to the Uplay server, hence you couldn't activate the game and couldn't start playing. To workaround this, change windows version to Windows XP, download Uplay from Ubisoft's website, install it, log in, close it, then relaunch steam, launch the game and it's going to find the *working* uplay. Uplay in itself has lots of issues which are described here.

What was not tested

Finishing the game, though it doesn't seem to be a problem, cause once you get into the game things work.

Hardware tested


  • GPU: Nvidia
  • Driver: proprietary

Additional Comments

Works well, but in my opinion not being able to alt-tab is preventing it from reaching gold. (The alt-tab issue might be an optimus thing, but still). I used an up2date system with: i7-7700HQ processor 1070M GPU Running bumblebee I run the game with maximum settings on 3k resolution. Changing settings doesn't result in noticeable performance difference. Performance is OK.
