Divide By Zero - a blog by Kamran Ayub

I recently acquired Assassin's Creed via Steam and I had a chance to test it out (using my friend's account). When I booted it up and turned on all the settings high and lowered the resolution, I got OK performance. It was playable but not as I'd like it. So I decided to try and use my SLi configuration that I paid over $300 for to try and increase my frames.

I have a 7900GS SLi system and Assassin's Creed for PC doesn't support SLi out of the box, but you can manually add a profile for it.

To do so:

1. Open nVidia Control Panel
2. Go to Manage 3D Settings
3. Click 'Add'
4. If you're using Steam, you need to browse to [Your SteamApps Folder]\common\assassins creed\
5. Depending on what DX version you're using, add the appropriate exe (mine is AssassinsCreed_Dx9.exe).
6. Scroll down to SLi Performance Mode.
7. Select 'Force alternate frame rendering 2'

I've tried 1 and 2, and 2 gives me a good extra 15-20 frames bringing it from barely playable to definitely playable (19 to above 30) in the temple intro. I have all settings High, Multisampling 1st level, and 1024x768. It brought the Animus screen from 30 to over 50.

To be fair though, I still can hardly play the game when in a city. Yuck.

I hope this helps someone get more performance!
