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.[1] However after many complaints from players and Steam users, the base game and expansion pack were eventually reinstated on Steam on November 3, 2012.[2][3]

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.[4] On February 27, 2023, the original Doom 3 and Resurrection of Evil was re-released through and bundled with Doom 3: BFG Edition.[5]

EAX support introduced in v1.3 suffers from frequent visual glitches.[6] 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.

Widescreen resolution

Use the dhewm3 source port[17]
Install the Doom 3 Enhanced Edition or Doom 3: Redux mod[18]
Manually edit DoomConfig.cfg[19]
  1. Open <path-to-game>\base\DoomConfig.cfg with a text editor (e.g. Notepad).
  2. 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).
  3. Search for the line seta r_mode "<value>" and set this to "-1" to enable custom resolutions in the game.
  4. 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.


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[20]
  1. Open the developer console with Ctrl+Alt+~ (Doom 3) or ~ (dhewm3).
  2. Type in g_fov <value> to the desired FOV value.


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[20]
  1. Open the developer console with Ctrl+Alt+~ (Doom 3) or ~ (dhewm3).
  2. Type in image_anisotropy <value> where <value> can be 1, 2, 4, 8; 8 being the Highest Quality.
  3. To apply new settings, type in vid_restart to restart the renderer.
Set AF manually in Configuration file[citation needed]
  1. Go to the configuration file(s) location.
  2. Open autoexec.cfg (Create if not present).
  3. Search & Edit the line seta r_multiSamples "value" (If not present, Add at the end of file).
"value" can take values as "1", "2", "4", & "8"; "8" being the Highest Quality.
For Improving the Visual Quality even further, Force Anisotropic Filtering via 'Nvidia Control Panel' OR 'AMD Catalyst'.

High frame rate

The game's frame rate is capped at 62.5 FPS.
Unlock the frame rate cap in dhewm3[21]
  1. Download dhewm3 version 1.5.2
  2. Apply the Unlocked FPS Patch for ver1.5.2 for dhewm3 1.5.2. Read here for Installation guide.
  3. Then, Either :
    1. Open Console(using ~), and type com_gameHz 120. Hit Enter.
    2. OR Edit autoexec.cfg, and add the line seta com_gameHz "120".
Tested for 120Hz Monitors.
Works for 'Resurrection of Evil' & The Lost Mission MODS as well.
For Users wanting even higher frame rates can try a similar Unlocked FPS Patch for ver1.5.1 but with a older dhewm3 ver1.5.1. See this & this for Installation guide.
Unlock the frame rate cap in DOOM3(Vanilla)[22]
  1. Open the developer console with Ctrl+Alt+~ (if the console is Locked) or ~ (if the console is Unlocked).
  2. Type in the following commands: com_fixedTic 1, com_preciseTic 0 (Doom 3). Or com_fixedTic -1
Highly NOT recommended as these cause Game Animation to become faster, thereby causing it to go De-Sync with the Game Audio, making the gameplay as well as the whole effort pointless.
Also leads to 'Slow Motion Effect' if used with V-Sync ON


The Game uses Multi-Sample Anti-Aliasing (MSAA).
Set AA manually in Console window
  1. Open the developer console with Ctrl+Alt+~ (Doom 3) or ~ (dhewm3).
  2. Type in r_multiSamples <value> where <value> can be 0, 2, 4, 8 & 16; 16 being the Highest Quality.
  3. To apply new settings, type in vid_restart to restart the renderer.
Set AA Manually in Configuration file
  1. Go to the configuration file(s) location.
  2. Open autoexec.cfg (Create if not present).
  3. Search & Edit the line seta r_multiSamples "value" (If not present, Add at the end of file).
"value" can take values as "0", "2", "4", "8" & "16"; "16" being the Highest Quality.
For Improving the Visual Quality even further, Force MSAA via 'Nvidia Control Panel' & 'AMD Catalyst'.


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.[23][24]
Set gamma manually[20]
  1. Open the console with Ctrl+Alt+~ (Doom 3 if the console is locked) or ~ (Doom 3 if the console is unlocked or dhewm3).
  2. Type in r_gamma <value> where <value> is the desired gamma levels (default 1).

Enable plasma gun projectile shadows

Edit found in pak000.pk4[25]
  1. Open <path-to-game>\base\pak000.pk4 with 7-Zip or a similar program.
  2. Go to materials folder.
  3. Open with a text editor.
  4. Search for the line plasmaglow, and delete the noshadows line under it.
  5. Save the changes and update the contents of pak000.pk4 when prompted by 7-Zip.

Disable head bobbing

Disable head bobbing through these settings[26]
  1. Create autoexec.cfg file in <path-to-game>\base.
  2. Add the following commands, and save the file.

Issues fixed

Textures are low-resolution, even on Ultra quality

This fix is included in the version.[31]
Force Ultra quality settings via autoexec.cfg[32]
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.


In case the in-game Text appears blurry/hazy, try Font Scaling Commands.
In case, some commands you Manually typed don't take effect, see Console Command Guidlines.
com_videoRam must be set explicitly. Value "-1" does not work in some cases.

Commands not taking effect even after including them in 'autoexec.cfg/DoomConfig.cfg'

Make sure your config file has *.cfg extension and NOT *.cfg.txt
Sometimes, when Users Share their set of settings/Console Commands over Internet OR when downloading a separate MOD, the block of lines that are Imported/Copied, have multiple Instances of the same command causing repetition of the same lines OR lines with different Values. This causes cvars to have their values wrongly configured, leading to undesired effects.
Make sure that every Command starts with seta and NOT seta_ OR set, as the Game Engine will ignore those lines.
Make sure that every Command has only One Instance in the Entire File

Make sure that every Command has only One Instance in the Entire File (i.e. it occurs only one Time in the File), because Multiple Instances can Override the value in the Previous occurrence of the same Command. The Command Line that occurs Last takes precedence over every previous occurrence.

For e.g., in the following set of lines :

seta r_renderer "best"
seta com_videoRam "1024"
seta com_machineSpec "3"
seta r_shadows "1"      // 1st Occurrence
seta r_skipBump "0"
seta r_skipBump "0"
seta r_skipSpecular "0"
seta r_skipNewAmbient "0"
seta r_shadows "-1"      // 2nd Occurrence
seta image_preload "1"
seta image_roundDown "0"
seta image_useAllFormats "1"
seta image_useCompression "0"
seta image_useNormalCompression "0"
seta r_shadows "0"      // 3rd Occurrence   

The Final Value of cvar r_shadows will be "0" as per the Last entry (3rd Occurrence).

Easier way to do this is using 'Find' Feature in Notepad/Notepad++ (Ctrl+F) and then 'Find Next' option, making sure there is ONLY One Instance of a particular command.

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[33]

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.

FPS Drops when viewing a scene with High Shadows OR Smokes

This happens due to a bug in the shadow rendering core of the Game. This will happen when too much Shadows come in the rendering volume.
Disable in-game Shadows using command r_shadows 0[34]
  1. Either, Open Console(using ~) and enter r_shadows 0. Then, enter vid_restart.
  2. OR, Open autoexec.cfg and add/edit line as seta r_shadows "0". Launch the Game.
Fixes nearly every FPS lag in the Game, as the shadow rendering in IdTech4 Engine is quite heavy.
Users cannot experience game with its True intended Visual Quality.
This issue has been Fixed in DOOM3 - BFG Edition.

Game starts with a fluctuating FPS, usually in range of 25-50 & doesn't reach 63-62 even on High-End systems

This bug is suspected to happen due to Memory leaks, which occur randomly, thereby causing this issue too hard to know and pinpoint.
Another reason cited is the Game being designed to run on single core systems during its time of Release.
'Exit' and 'Restart' the Game untill FPS Counter shows 63-62[35]
Keep doing this untill FPS Counter shows 63-62. Sometimes this needs to be done 3-4 Times if you have bad luck.
Make sure the game is running on 'High Performance Mode'
If NOT, then Force it via 'Windows Gaming Mode' as well as your 'Video Card Software'.
Use dhewm3 Source Port instead
Highly recommended as dhwem3 source port has been designed to take advantage of modern multiple core systems.

Micro stuttering

This issue is caused when playing the game on 60Hz Display, while the game's internal ticrate being tied to 62.5 FPS cap.
Users playing on High Refresh Rate Displays(90hz, 120 Hz, etc.) wouldn't experience this in first place.
'Unlock the FPS' in-game and then 'Limit the FPS' via your Video Card Software
  1. Open autoexec.cfg and add the lines seta com_FixedTic "1" and seta r_swapInterval "0".
  2. Force V-Sync(Normal V-Sync) via 'Nvidia Control Panel' OR 'AMD Catalyst'.
  3. Limit FPS being generated by CPU to 60(exact) via 'Nvidia Control Panel' OR 'AMD Catalyst'.

Improving performance for low-end systems

Configuration files[citation needed]
  1. Open DoomConfig.cfg file
  2. seta image_useCache "1"
  3. Set image_cacheMegs to about 1/4 of the machine's total system RAM.
  4. Set image_cacheMinK = "image_cacheMegs" × 128
  5. 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"

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.
This happens due to V-Sync being ON while com_preciseTic and com_FixedTic are set to anything other than value 0.
Add the lines seta com_FixedTic "0", seta com_preciseTic "0" & seta r_swapInterval "0" in autoexec.cfg

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.[36]
If this still doesn't work, try the old SBA2_BETADRV_US_2_05_0000 drivers (works only on Windows XP).[37]
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.

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]

Game won't launch correctly (Linux on Retail)

Remove the included and 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]
  1. Open and edit the config file.
  2. Find seta s_alsa_pcm and replace default with the name of the ALSA audio output, for example hw:0,0.
  3. Save the file.

I also tested a few random CD keys from the retail version that may have already been used, but they also still worked, even on the Steam version's executable while disconnected from the internet. I can also confirm that using my CD keys with the retail version also worked and vice-versa.
