How to Fix Assassins Creed Revelations (crashes, freezes, lag, no sound, etc)

Assassins Creed: Revelations Game FixesAssassin’s Creed: Revelations (ACR) is now out! This series…is far too fun to be healthy. Really — you can lose hours upon hours of your time far too easily. You can start playing at 6PM, to find out later than it’s already 6AM! This game isn’t available for Steam / Steamworks yet (there was a delay unfortunately), but it is available on Windows XP / Windows 7 / vista (PC), Xbox 360, and PlayStation 3 (PS3) consoles. This troubleshooting guide will pertain to the computer (PC) version mostly though. Note that if you are a Mac user, then you will have to wait awhile before the game is released on Macintosh. There is no set release date for that yet, but Ubi is pretty good at releasing titles on Mac OS / OSX.

If you’re outside of the USA, then you can pick up the Animus Edition for extra content, such as a bonsu singleplayer gameplay mission, an exclusive multiplayer character, 3 weapon capacity upgrades, an animated short film, and the original game score soundtrack! You can get the Signature / Delux / Collectors Edition too from Gamespot in the US. Thanks Ubisoft. You can even play this game online, by the way, since it has multiplayer support…so connect with your friends (if you have any!…you do, right?).

So although this game plays perfectly for some people, others may find that they need to troubleshoot to get passed some game bugs, glitches, or errors. We are here to help you though! And if you know any solutions we don’t, then please share!


Assassin’s Creed: Revelations Game Controller Not Working

Plug in your Xbox 360 controller or a different one? Too bad, it’s nice to give love to your keyboard and mouse. In any case, try the following:
— Exit the game and reopen it
— Plug the controller in BEFORE you open the game
— Restart your computer
— There are some programs that won’t let your controller work so ensure you have no such thing open
— Ensure your controller drivers are working / upgrade if you can!
— Unplug other USB devices and ensure that you are using the same USB port that you usually do for the controller


Assassin’s Creed: Revelations Crashing / Failure to Launch / Freezing

This is pretty broad and applies to when AC:R crashes to desktop (CTD / C2D), fails to launch after you open it (a black screen for instance), or simple becomes frozen or haults / stalls.
— Run the game in Windows XP compatibility mode (on the EXE, right click -> propertes -> then set it here)
— Exit or stop any software that may interfere with the game (some antivirus or firewall software is imfamous for causing crashes)
— Upgrade your drivers for your video card! If you are using very outdated graphics card drivers for your NVIDIA or AMD ATI card, then you will get additional compatibility, as well as optimization done to increase your frame rate / frames per second (FPS) You can find video card drivers here.
— Set your resolution to something more common
— If you use more than one computer monitor, disable them so that only ONE is enabled
— Set the game’s EXE affinity to Core 0 and Core 1 through Task Manager (CTRL+ALT+DEL > Processes > Right Click EXE > Set Affinity). If it doesn’t work then disable it! This is a last resort.
— Run the game as ADMIN / ADMINSTRATOR


Assassin’s Creed: Revelation Lagging

If your game is stuttering, has lag, or you have skipping or choppy frames, then try these tips.
— Lower your game graphics settings, especially the resolution
— Exit every application you don’t need open (web browsers for instance)
— Upgrade your video card drivers. You can find video card drivers here.
— If on Windows Vista or Windows 7, set your compatibility mode to Windows XP and see if it runs any better!
— Turn OFF VSYNC / AntiAliasing (AA)


Assassin’s Creed: Revelations Has No Sound

Music, sound, and general audio FX are important in a game like ACR. You shouldn’t have to go without them! These tips also help with people who use headphones or headsets too.
— Turn off hardware acceleration by going to Control Panel > Sounds & Audio Devices > Volume > Speaker Settings > Advanced > Performance. Move the hardware acceleration slider all the way to the left. You can also try to lower your Sample Rate Conversion Quality to “GOOD” instead of “BEST”
— If using a 5.1 or 7.1 speaker configuration, tell Windows to use 2.1
— Set your audio playback to 16bit 48000hz playback
— Upgrade your sound card’s drivers
— Open DXDIAG and under turn off hardware sound acceleration (Start > RUN > DXDIAG > Sound > DirectX Features)


Xbox 360 ACR Isn’t Working / Bad Performance!

There is one suggested fix here that usually helps if AC:R isn’t working on your Microsoft Xbox 360…and that is to clear your game cache! This usually helps if your game is running slowly too so you may expect a performance increase.

    I had this problem where the game would not run and tried all these plus some listed on other sites but nothing worked. Then after looking at the log files I searched google for the error removing a little every time I got no hits till it got something. I found out that the alky project that was trying to port direct x 10 to windows XP. I hat installed a few months ago makes a few games do that. Here is the solution I used that fixed it for me.

    Go to Add / removed programs and remove the direct x 10 and then

    C:\WINDOWS\system32 then delete the files below if they still exist.


    Once done you might need to install direct x 9 (I didn’t but who knows).
    After all of that is done try the game again.

    While the sequence 6 is loading, it always gets stuck. Exited the game and re-launched it a lot of times, still doesn’t fix the problem. Tried everything you’ve mentioned above, too. What do i do? 🙁

    Assassin’s Creed: Revelations Crashing / Failure to Launch.

    Okay guys and girls
    If your problem are about this : “Clicking the ACRSP or ACRMP but get a black screen then crash to desktop or nothing happen” or get a “alkylog readme” in the main ACR folder that show : Log (NuContext): Setup Log (NuContext): Setup Error (NuCore): Unsupported function called from 073655EB: IDXGIAdapter_CheckInterfaceSupport

    Well after searching for the “Fix”, I finally found one. Give credit to the “Guy” that found the solution by himself not me 🙂 (sorry forgot his nickname).

    Here is what you have to do:

    1.Go to “C:\WINDOWS\system32” or go to “my computer”, then “Local disk C”, then “WINDOWS”, then scroll down until you
    found “system 32”.

    2. Scroll down again until you found the following

    Make a backup of this file first by copy and paste, simple :D.

    3. After founded it, simply delete it.

    Note: I found it working, but get a pop-up error after the intro of the ubisoft logo but I simply click the game again (Not the launcher but the “minimize launcher”, dont get it? Look at the most bottomless screen of your desktop, and you will see a ACR launcher which been minimize. p.s This is my problem, but still it work.

    But keep in mind, there are still many reason why your game doesnt work, see the requirement for example :). Maybe your com need an upgrade.

    Okay enough reading this, “There are templars to be hunt down” lol

    I have the same problem as C0mrade and syncronize, and it seems a lot of people also do.
    Now i’ve found a few places where a fix is offered, but it erases the saves.
    Is there a way to fix it without losing all progress?

    Judging by the number of people having this problem it should be adressed as soon as possible.
