Warnings

The macOS (OS X) version of this game needs a fix to work on macOS Catalina (version 10.15) or later (see API for details).

Doom 3 (stylized as Doom³) is a singleplayer and multiplayer horror sci-fi FPS game developed by id Software and published by Activision. It is part of the Doom series, but rather than being a continuation of the storyline of its predecessors, it is a reboot of the series, and uses the id Tech 4.

On October 15, 2012, publisher Bethesda Softworks delisted the original Doom 3 and Resurrection of Evil expansion pack from all digital storefronts outside of the Super id Software Pack on Steam in preparation of Doom 3: BFG Edition. However after many complaints from players and Steam users, the base game and expansion pack were eventually reinstated on Steam on November 3, 2012.

On August 10, 2022, Bethesda has simplified and merged all store listings of the original Doom 3, the Resurrection of Evil expansion pack, and Doom 3: BFG Edition into one package on Steam. On February 27, 2023, the original Doom 3 and Resurrection of Evil was re-released through GOG.com and bundled with Doom 3: BFG Edition.

EAX support introduced in v1.3 suffers from frequent visual glitches. See visual twitch bug with OpenAL/EAX for a solution. The game does not properly recognize the available VRAM on modern graphics cards, and as such forces the game to use lower image quality settings. See Forcing Ultra quality settings for a workaround with modern graphics cards.

Use the dhewm3 source port

Install the Doom 3 Enhanced Edition or Doom 3: Redux mod

Manually edit DoomConfig.cfg

Open <path-to-game>\base\DoomConfig.cfg with a text editor (e.g. Notepad). Search for the lines seta r_customHeight "<value>" and seta r_customWidth "<value>" and change them to desired resolution values (e.g. seta r_customHeight "1080" and seta r_customWidth "1920" for 1920x1080). Search for the line seta r_mode "<value>" and set this to "-1" to enable custom resolutions in the game. Search for the line seta r_aspectRatio "<value>". For 4:3 resolutions (e.g. 1024x768), set this to 0. For 16:9 or 21:9 resolutions (e.g. 1920x1080), set this to 1. For 16:10 or 15:9 resolutions (e.g. 1920x1200), set this to 2. Notes This method assumes the latest patches are installed as it involves setting a game variable that did not exist in the earliest retail versions, otherwise this will not work. If these lines are not available in the DoomConfig.cfg file, then add them manually. 21:9 ultrawide users will also need to install an aspect-ratio FOV fix for both Doom 3 and Resurrection of Evil. These values can be set in the developer console. Omit the command seta when doing so, and use vid_restart to apply changes. HUD, menus, and FMV cutscenes are stretched unless played on CstDoom3. dhewm3 can also fix menu scaling.

Field of view (FOV)

Set FOV manually
Open the developer console with Ctrl+Alt+~ (Doom 3) or ~ (dhewm3). Type in g_fov <value> to the desired FOV value. Notes Alternatively, g_fov <value> can be manually edited in DoomConfig.cfg. In multiplayer, g_fov can only be changed between 90 and 110.

Anisotropic filtering (AF)

Anisotropic filtering scales with the "Video Quality" option.

Set AF manually
Open the developer console with Ctrl+Alt+~ (Doom 3) or ~ (dhewm3). Type in image_anisotropy <value> between values of 1-8. To apply new settings, type in vid_restart to restart the renderer.

High frame rate

The game's frame rate is capped at 62.5 FPS.

Unlock the frame rate cap

Open the developer console with Ctrl+Alt+~ (Doom 3 if the console is locked) or ~ (Doom 3 if the console is unlocked or dhewm3). Type in the following commands: com_fixedTic 1, com_preciseTic 0 (Doom 3). Or com_fixedTic -1 (Dhwem 3 provides a built-in fps uncap feature with correct game physics, making the following step optional for later versions) Apply the uncapped FPS fix for dwehm3; otherwise, issues such as audio desyncing during cutscenes or the game speed becoming too fast can occur. Some have reported the DLL causes crashes.

Gamma

Adjusting the game's gamma and brightness levels with the stock Doom 3 engine will also affect the operating system. dhewm3 as of v1.5.2 by default fixes this by allowing gamma and brightness levels to be adjusted through shaders instead; the original behavior can be restored by setting the value of the r_gammaInShaders CVar to 0.

Set gamma manually
Open the console with Ctrl+Alt+~ (Doom 3 if the console is locked) or ~ (Doom 3 if the console is unlocked or dhewm3). Type in r_gamma <value> where <value> is the desired gamma levels (default 1).

Enable plasma gun projectile shadows

Edit lights.mtr found in pak000.pk4
Open <path-to-game>\base\pak000.pk4 with 7-Zip or a similar program. Go to materials folder. Open lights.mtr with a text editor. Search for the line plasmaglow, and delete the noshadows line under it. Save the changes and update the contents of pak000.pk4 when prompted by 7-Zip.

Disable head bobbing

Disable head bobbing through these settings
Create autoexec.cfg file in <path-to-game>\base. Add the following commands, and save the file. seta pm_runbob "0" seta pm_runpitch "0" seta pm_runroll "0" seta pm_walkbob "0" seta pm_bobpitch "0" seta pm_bobroll "0" seta pm_bobup "0" seta pm_crouchbob "0"

Issues fixed

Visual twitch bug with OpenAL/EAX

Using OpenAL (seta s_useOpenAL "1" in DoomConfig.cfg), which was added with patch 1.3 and is automatically engaged when EAX is turned on, results in frequent visual twitching/screen shifting. It is currently unknown whether this happens on all configurations, but the problem persists in the latest patch. A video of the glitch in action can be seen here (0:07, 0:11).

Use a SoundBlaster Audigy card.
If this still doesn't work, try the old SBA2_BETADRV_US_2_05_0000 drivers (works only on Windows XP).

Use the patcher provided in EAXEFX.

Incorrect EAX effect in Doom3: Resurrection of Evil with OpenAL/EAX

X-fi and audigy 2 Sound card are not affected by this problem.^{[citation needed]}

Post X-fi card, that use Host openAL drivers from Creative and OpenAL Soft are concerned by this bug.

The patch 1.3 has been shipped with incorrect EFX files for the expansion Ressurection of Evil, these files control EAX effects to apply in each zone of a level. The problem is due to a missing parameter "air absorption hf" in each zone of each level file.

Download fix EFX files Doom3_ROE_EAX_FIX.

Use the patcher provided in EAXEFX.

Weapons sound being "drowned" or near inaudible

OpenAL scales down all sounds temporarily if the mixed result would be too loud. This could happen in doom3, especially when using EAX. The patcher below will provide a fix that consist of scaling down volume of all sounds to prevent the issue (just set your system speaker volume a bit higher if needed).

Use the patcher provided in EAXEFX.

Textures are low-resolution, even on Ultra quality

This fix is included in the GOG.com version.

Force Ultra quality settings via autoexec.cfg

1. Go to <path-to-game>\base. 2. Create a new file called autoexec.cfg if one did not already exist. 3. Add the following lines in the autoexec.cfg file: seta r_renderer "best" seta com_videoRam "1024" seta com_machineSpec "3" seta r_shadows "1" seta r_skipBump "0" seta r_skipSpecular "0" seta r_skipNewAmbient "0" seta image_anisotropy "8" seta image_filter "GL_LINEAR_MIPMAP_LINEAR" seta image_ignoreHighQuality "0" seta image_roundDown "1" seta image_preload "1" seta image_forceDownSize "0" seta image_downSize "0" seta image_downSizeBump "0" seta image_downSizeSpecular "0" seta image_useCache "0" seta image_usePrecompressedTextures "0" seta image_useNormalCompression "0" seta image_useCompression "0" seta image_useAllFormats "1" seta g_showBrass "1" seta g_decals "1" seta g_doubleVision "1" seta g_bloodEffects "1" seta g_projectileLights "1" seta g_muzzleFlash "1" 4. Save the file. The game should now default to Ultra quality every time it is launched. 5. (Optional) Copy the newly created autoexec.cfg into the <path-to-game>\d3xp for Resurrection of Evil and any mod folders to apply these changes automatically when loading the expansion pack and respective mods. Notes: com_videoRam must be set explicitly. Value "-1" does not work in some cases.

Micro stuttering

This issue is caused by the game's internal ticrate being tied to 62.5 FPS cap on 60 Hz displays.

See High frame rate for a potential workaround

Low resolution font scaling

By default, some of the game's text fonts render at a lower resolution due to a font scaling limiter.

Remove the font scaling limit
1. Add the lines to autoexec.cfg or change it manually in DoomConfig.cfg: seta gui_mediumFontLimit "0" seta gui_smallFontLimit "0" 2. Save the file. The game should now render the text in higher quality regardless of resolution.

Improving performance for low-end systems

Configuration files[citation needed]
Open DoomConfig.cfg file seta image_useCache "1" Set image_cacheMegs to about 1/4 of the machine's total system RAM. Set image_cacheMinK = "image_cacheMegs" × 128 Save the file and start the game. Assuming at least 1 GB of system RAM is used: seta image_useCache "1" seta image_cacheMegs "256" seta image_cacheMinK "32768"

Mouse not working

Wired mouse: doom3.exe executable name[citation needed]

Wireless gaming mouse: Set the mouse's rate to at least 250[citation needed]

Poor performance/"slow-motion" effect on Nvidia cards

Doom 3 and other id Tech 4 games suffer from a potential driver-related issue on modern Nvidia GPUs that causes the game to go into what appears to a "slow-motion" phase during some intensive scenes, where the framerate technically remains the same but game logic is slowed down and negatively effects performance, and it persists even when using the dhewm3 sourceport and/or microstutter fix. This issue can potentially be fixed through using an autoexec.cfg file containing the necessary CVar tweaks.

Configure an autoexec.cfg file according to this Steam guide.[citation needed]

Game won't launch correctly (Linux on Retail)

Remove the included libgcc_s.so.1 and libstdc++.so.6 from the installation folder[citation needed]

No Sound (Linux)

Use the OSS wrapper for specific audio device[citation needed]

Specify the default audio output[citation needed]
Open and edit the config file. Find seta s_alsa_pcm and replace default with the name of the ALSA audio output, for example hw:0,0. Save the file.
