Issues unresolved

No background music

Often after the game starts, the background music does not play.[5][6]
Keep restarting the game until the music starts playing[7]

Issues fixed

Stuttering/Tearing with Vsync On or Off

Ingame FPS Cap workaround and CPU load fix
This is caused by 2 issues - a uneven 59fps fps cap and excessive CPU load when using Vsync
To fix the uneven cap. Set the refresh rate to 50hz in game instead (use CRU in case no such option is available in game for you) and use the Vsync as below:
  • For Nvidia cards: use Nvidia's Adaptive Vsync in the Nvidia Control Panel. This minimizes Vsync drops to 25fps
  • For newer AMD cards: turn on Radeon Chill as an FPS limiter set to 50/50 (min/max) and also turn on the "Enhanced sync" feature (don't forget to turn Vsync off in-game for AMD's enhanced sync to work).
  • The alternative, if the other 2 are not possible for you, use the normal in-game Vsync on.
When using VSync, excessive single core use is also evident (typically 99%) with any Quad Core CPU and above. Removing the first core of your CPU availability manually using the Task Manager affinity or alternatively using utility Process Lasso to automatically remove CPU 0 access from the AC2 executable resolves this.

The affinity fix also fixes the same issue with ACB, ACR and AC3 when using VSync.

Making affinity changes permanent (setting affinity in task manager only lasts until you exit the game):
  1. Edit your preferred shortcut for launching the game (desktop and/or start menu)
  2. In the target field, set the following (just put the default contents in double quotes and prepend cmd.exe /C ...):
  • For a 4/4 (core/thread) CPU cmd.exe /C start "" /affinity e "<path-to-game>\AssassinsCreedIIGame.exe"
  • For a 4/8 and 8/8 (core/thread) CPU cmd.exe /C start "" /affinity fe "<path-to-game>\AssassinsCreedIIGame.exe"
  • For a 6/6 (core/thread) CPU cmd.exe /C start "" /affinity 3e "<path-to-game>\AssassinsCreedIIGame.exe"
  • For a 6/12 (core/thread) CPU cmd.exe /C start "" /affinity 7fe "<path-to-game>\AssassinsCreedIIGame.exe"
  • For a 8/16 (core/thread) CPU and higher cmd.exe /C start "" /affinity fffe "<path-to-game>\AssassinsCreedIIGame.exe"
Verify correct affinity by launching the game and checking affinity in task manager (see beginning)
To be used in Steam launch options, to launch the game directly from Steam, it must be a little different:
  • Ex. for a 8/16 (core/thread) CPU and higher C:\Windows\System32\cmd.exe /C start "" /affinity FFFE "<path-to-game>\AssassinsCreedIIGame.exe" %command%

Nvidia Control Panel Fix[citation needed]
This issue is cause by the Nvidia Control Panel forcing graphical settings on.
  1. Enter Nvidia Control Panel.
  2. Select "Adjust image settings with preview".
  3. Select "Let the 3D application decide".

Game freeze when given hidden blade

Press "2" to select the weapon to continue the cut-scene[citation needed]
Default mapped keys do not work as they should.

Error "A Ubisoft service is unavailable at the moment"

Download and install the UPlay client[citation needed]

Program hangs and screen flashes repeatedly on launch

Set monitor resolution to 1280x720 on launch and change resolution in-game[citation needed]
