First of all, download the 1.2 patch (~12MB), which will fix some of these problems.
These suggestions are not guaranteed to work, and nor are they official. They are simply a collection of common problems and possible fixes suggested by forum members. There is a patch in the works, which we all hope will fix a lot of problems, but in the meantime you can give these suggestions a go. Iím no techie (and I don't even have the full game yet) so feel free to post corrections or further suggestions in this thread.
Some of these tweaks require you to alter some .ini files; namely, the default.ini file in the DXIW\System folder, and the user.ini file in the My Documents\Deus Ex Ė Invisible War folder. Itís a good idea to back these files up before altering them: just copy and paste the file to a different location on your hard drive, and if something goes wrong, just copy-paste the original file back. To open these files, use Notepad or Wordpad. Wordpad is probably best because Notepad can mess up the layout.
- First of all, youíve heard this a million times before, but update your drivers! Get the latest drivers for your video card, sound card, motherboard, get the latest firmware for your CD/DVD-ROM, and download the latest version of DirectX (not the debug version).
- One thing everyone should definitely do is fix the mouse lag. Open up default.ini and find the line
Change the 75 to a 0 and your mouse should be much more responsive.
- Read through Eleazarís tweak guide and try some of those tips.
- Read through this tweak guide at the Ion Storm forums and try some of the tips there.
- Download a DX:IW tweaker program. You can find links for them in those two tweak guides.
- A tweak that should help performance for everyone is the cache size. Open default.ini and find the line
Change the 1 to 16 or 32. You probably wonít notice much difference above 32.
- Windows XP users: several members have reported much improved performance when running the game in Windows 2000 compatibility mode. Create a shortcut to DX2.exe on the desktop, right-click it, go to Properties>Compatiblity, and select Win2000 mode. Run the game from that shortcut.
- If you have a gamepad or joystick connected to your computer, try removing it before playing. It might improve performance.
- KR_Dragon suggested this tip concerning audio systems:
Okay, this might work for you guys... I was poking around in the demo's .ini file and found something interesting. DX:IW is initializing two seperate audio subsystems which may be the cause for performance degredation... Hehe, its the XBox audio subsystem at that.... Go into the [Engine.Engine] group and find this line, put a comma at the beginning of it like so.... The openAL audio system should be the only one enabled.
- Set your video cardís antialiasing setting to ĎApplicationí (all the way to the left) and set anisotropic filtering to Off. You can control AA from within the game. To change these settings, right-click your desktop, click Properties, click the Settings tab, click the Advanced button, then click your video cardís tab.
- In direct contradiction to this (welcome to the world of computers), it might help performance to set your video cardís AA and anisotropic filtering settings to 2X. Who knows.
- The Windows 2000 compatibility tweak can help with crashes too.
- If the game is crashing while youíre loading it, and/or maps take a long time to load and the game eventually crashes, try updating your CD/DVD-ROM firmware from the manufacturerís website. The problem might be related to disc access times.
- Run Windows at the same resolution youíre running the game at. For example, if youíre running the game at 800x600, put your Windows resolution at 800x600.
- Similarly, if your game is crashing when you load saves, try changing the menu resolution when you first start the game. It defaults to 640x480 on startup, so, for example, if you saved the game at 800x600 resolution, change the resolution to 800x600 before loading a save.
- You can try running the game in debug mode. This will increase loading times, but may help stability. For instructions about this, see this forum thread.
- Some players have had problems when installing the game to a custom directory. Try installing the game to the installerís default directory.
- If all else fails, you try holding down the escape key during level loads. This has worked for some people, though obviously itís not ideal.
- If you receive an error message saying Your PC doesnít have enough free space to start a new game, it may be because youíve changed the location of the My Documents folder. Move it back to the original location and try again.
If your My Documents folder must be shared, you can (sort of) get around it by disabling sharing, loading the game, and creating a few saves. You will then be able to overwrite those saves and use the quicksave even if your My Docs is shared. You just won't be able to create new saves.
Error messages with the DVD version
If you're getting messages like 'conflict with disc emulator software' or 'insert original disc, not a backup', etc, try downloading this new .exe file, which might help.
Game freezing with Radeon 9600 cards
Take a look at this thread.
Slow, stuttering intro and endgame movies
Download the RAD Video Tools, which let you watch the .bik video files in Windows. (Thanks grommit.)
Dotty grey pixels on Radeon cards:
This seems to be caused by a combination of Bloom and Multisampling. Turn off one setting or the other and it should help. Hopefully this will be fixed in future ATI drivers updates.
Geforce cards and Bloom effect:
There may be a problem with the Bloom effect with some Nvidia drivers. Updating the drivers to the latest version should fix the problem.
Alt-tabbing during level loads
If this is happening to you, and you are running Windows XP, run the game in Win 2000 compatability mode.
Mouse not working in menus
Several people have solved this problem by downloading the latest drivers for their video card.
Try the suggestion in this thread.
Another possibility is this fix discovered by forum member Jovena:
3D sound fixuse your 'Run" option in the start menu and enter this:
click on startup now click disable all.
I re-selected my startup for my wireless internet connection so that it would be the only thing still in my startup menu. You may need to do this as well if you have Internet issues.
I am running WinXp and this procedure does not turn off any critical programs.
nRaecheR on the Ion Storm forums has made a 3D sound .dll file to enable surround sound on Audigy and other sound cards. Find information and instructions in this thread.
Surround sound with nForce motherboards:
This seems to be a problem with the nForce drivers. Downloading the beta 3.75 audio drivers may fix the problem. These drivers are not official and you use them at your own risk! Check this thread for more information about them.
Try to keep this thread clean. If you have a problem and need some help, post in a different thread or start a new one. Keep this thread for more suggestions (or corrections).
