About Dhewm 3
Dhewm 3 is a source port of the original Doom 3 (not Doom 3 BFG, for that you may
want to try RBDoom3BFG). It's known to work on Windows, Linux, macOS, FreeBSD,
OpenBSD and AROS, but it should work on (or be easily portable to) any system that
supports OpenGL 1.4 with ARB shaders, SDL and OpenAL.
Compared to the original version of Doom 3, Dhewm 3 has many bugfixes,
supports EAX-like sound effects on all operating systems and hardware
(via OpenAL Softs EFX support), has much better support for widescreen
resolutions and has 64bit support.
It only supports old Mods if they either don't require their own game
DLL or have been ported to Dhewm 3 - see the Mods page for more information.
Mod-binaries who are supported, are bundled with Dhewm 3. External data is still required.
Note that while the Doom 3 source code has been released under GPL, you still need to
legally own the game and provide Dhewm 3 the game data to play. See the How to Install
section for more information.

| Release notes | Rejoice, dhewm3 1.5.5 is here! There have been lots of changes (see below for details), one highlight is that several sources of microstutters have been removed (like the old 60 vs 62.5fps problem) so the game should run smoother than before, especially when using VSync. Another great new feature is the support for widescreen GUIs. It requires adjusting the .ui files; *Arl* created versions for the base game, Resurrection of Evil and The Lost Mission, they are provided as an optional Download (dhewm3-wide-guis-\*.zip). Note that especially the main menus may have some little glitches here and there - they're very big/complex, so converting them to widescreen wasn't exactly straightforward. Furthermore, dhewm3 now supports BC7-compressed (BPTC) .dds textures. They offer better quality than the older S3TC/DXT/BC1-3 texture compression standard that Doom3 always supported, at the same size as DXT3-5. Useful for high-res retexturing packs. See the full changelog below for more details. You can download a signed and notarized build for macOS (Apple Silicon and 64bit Intel) at https://www.macsourceports.com/game/doom3 dhewm3-mods contains some new mods: • ELDOOM • Grimm • HeXen: Edge Of Chaos Demo • Real Gibs • Note: The page says it only works with the 32bit version of dhewm3, but that refers to the realgibs.dll they ship. Use their gamedata with the .dll/.so provided here (or build the lib yourself) • Blood Mod has been updated to v1.8 and now also supports Resurrection Of Evil • LibreCoop is now maintained as part of dhewm3-sdk, until upstream becomes active again. This means that you should use the librecoop.dll/.so/.dylib provided by the dhewm3-mods download • All mods got updated with gamecode changes from dhewm3 1.5.5 _Update:_ Now there's also builds for arm64 Linux, thanks to @TheMidnightHammer! Changes since 1.5.4: • Enable/disable Soft Particles when loading a graphics quality preset (only enabled in Ultra preset, though you can still configure it… |
