dhewm3 Changelog

Note: Numbers starting with a "#" like #330 refer to the bugreport with that number at https://github.com/dhewm/dhewm3/issues/

1.5.5 (WIP)

• Enable/disable Soft Particles when loading a graphics quality preset (only enabled in Ultra preset, though you can still configure it independently as before; #604)
• Support SDL3 (SDL2 and, to some degree, SDL1.2 are also still supported)
• Fix bugs on 64bit Big Endian platforms (#472, #625)
• Fixes for high-poly models (use heap allocation instead of alloca() for big buffers; #528)
• Fix building dhewm3ded with newer OpenAL Soft headers (#633)
• Better support for High-DPI mice:
  • Don't ignore mouse input on fast movement ("ridiculous mouse delta"), #616
  • Allow setting sensitivity to values < 1 in the dhewm3 settings menu to allow sane speeds for looking around with High-DPI mice (otherwise it might be way too fast)
• Fix a crash (assertion) on start with ImGui if SDL_GetWindowDisplayIndex() or SDL_GetDisplayDPI() failed and the imgui_scale CVar was set to the default value of -1 (setting it to 1 worked around the bug; #632)
• Updated Dear ImGui to 1.91.4

1.5.4 (2024-08-03)

• A brand new settings menu that uses Dear ImGui.
  Can be opened with F10 (unless that key is bound already) or by entering dhewm3Settings in the console. It has lots of settings that the original options menu doesn't have and can be easily navigated with gamepad or keyboard (or the mouse, of course). It can also be opened while in the game, which then is paused (if Single Player) but still visible, so the effect of most graphics settings can be seen immediately. Needs SDL2 and C++11.
• "Soft" Particles (that don't "cut" into geometry but fade smoothly), based on code from The Dark Mod 2.04. Can be enabled/disabled with r_useSoftParticles, is applied automatically for all appropriate particles (view-aligned, using additive or alpha blending and not too small).
  NOTE that on some systems Soft Particles noticeably slow down rendering. If dhewm3 doesn't run as smoothly as you'd expect, try disabling them (r_useSoftParticles 0 or in the new Settings Menu under Video Options -> Use Soft Particles)
• r_enableDepthCapture: Enable capturing depth buffer to texture, needed for the soft particles. Can be used in custom materials by using the "_currentDepth" texture
• Replaced dependency on (external) zlib with integrated miniz
• HighDPI/Retina support
• Allow inverted mouse look (horizontally, vertically or both) with m_invertLook
• CVar to allow always run in single player (still drains stamina though!): in_allowAlwaysRunInSP
• VSync can be enabled/disabled on the fly, without restarting the renderer (still with r_swapInterval or in the menu, of course; needs SDL2)
• Allow enabling/disabling HRTF with s_alHRTF
• s_alOutputLimiter: Configure OpenAL's output-limiter which temporarily reduces the overall volume when too many too loud sounds play at once, to avoid issues like clipping
• s_scaleDownAndClamp: Clamp and reduce volume of all sounds to prevent clipping or temporary downscaling by OpenAL's output limiter
• If r_windowResizable is set, the dhewm3 window (when in windowed mode..) can be freely resized. Needs SDL2; with 2.0.5 and newer it's applied immediately, otherwise when creating the window.
• If switching between fullscreen and windowed mode or similar changes causes issues (like here), you can set r_vidRestartAlwaysFull 1, so (again) a full vid_restart is done, instead of the partial one which usually suffices for just changing the resolution or fullscreen state. If you run into that issue (probably a driver bug), you'll probably also want to set r_windowResizable 0, because resizing the window that way also triggered the bug, and in that case no vid_restart is done at all
• Fixed screenshots when using native Wayland (SDL_VIDEODRIVER=wayland)
• If you enter the map command in the console, without any arguments, the current map name is printed
• Support OpenGL debug contexts and messages (GL_ARB_debug_output). Can be enabled with r_glDebugContext 1. Changing that CVar requires a vid_restart (or set it as startup argument)
• The Mods Menu's entries for the base game and d3xp/RoE are now clearer, and it can load the new d3xp-based mods (sikkmodd3xp, perfected_roe)

1.5.3 (2024-03-29)

• Support for gamepads (based on code from Quadrilateral Cowboy, but heavily expanded). See Configuration.md for more information.
• Support different file formats for screenshots by setting the r_screenshotFormat CVar (0 = TGA, still the default, 1 = BMP, 2 = PNG, 3 = JPG). r_screenshotJpgQuality and r_screenshotPngCompression allow configuring how JPG/PNG are compressed. Thanks eezstreet (Nick Whitlock)!
• Fixed problems with lights after loading a savegame (#495)
• Fix volume of some weapon sounds, like chaingun being too quit (#326)
• Increase stack size on Windows to 8MB (instead default of 1MB) to make loading huge models work
• Fixed crash in Radiant Model Preview Dialog (#496)
• Fix MD3 model support
• Several new CMake options:
  • To enable Clang/GCC Address Sanitizer and Undefined Behavior Sanitizer
  • Hardlink the game code into the executable (instead of using game DLLs, only supports base or d3xp then; needed for Undefined Behavior Sanitizer)
  • Force colored diagnostic output from GCC or Clang (esp. useful when building with ninja)
• Fix several compiler warnings
• Added build instructions for Linux (and similar systems) to README.md
• Updated stb_image and stb_vorbis
• Updated minizip (from zlib/contrib) to latest upstream code
• Added in_namePressed CVar to print currently pressed key/button (useful for binding keys in the console or configs). Thanks Biel Bestué de Luna!

1.5.2 (2022-06-13)

• Gamma and Brightness are now applied in the shaders instead of by setting hardware gamma.
  Can be disabled (so hardware gamma is used again) with r_gammaInShaders 0
• Improvements for (Windows-only) MFC-based tools:
  • Added the script debugger! (thanks HarrievG!)
    Original Doom3 didn't have it (Quake4 did), but the Doom3 GPL source contained most of it. HarrievG implemented the missing parts and we added some new features. It can even be used over the network and while the client part (the debugger GUI) is Windows-only, the server can run on all supported platforms, so you can debug a game running on Linux or macOS, for example.
    Relevant CVars for network debugging are: com_enableDebuggerServer and com_dbgClientAdr and com_dbgServerAdr.
    To debug the running game on the same PC, just enter debugger in the console.
  • All tools can now be built in 64bit (thanks raynorpat!)
  • HighDPI support (thanks HarrievG!)
  • PDAEditor works now
  • Additional bugfixes
• Cycle through multiple Quicksave slots instead of immediately overwriting the last Quicksave. The com_numQuicksaves CVar allows setting the number of QuickSaves (#392)
• Make r_locksurfaces work (#357)
  It doesn't do exactly what its description and name suggests: it renders everything that is currently visible from the position/view the player had when setting r_locksurfaces 1. Originally it was supposed to render exactly the surfaces that were visible then, but I couldn't get that to work.
  This is pretty similar, but there may be differences with opened doors and such.
• Keyboard input improvements (mostly SDL2-only):
  • Support (hopefully) all keyboard keys on all kinds of keyboard layouts by using scancodes for otherwise unknown keys
  • Support typing in non-ASCII characters, if supported by Doom3 (it supports ISO-8859-1)
  • Support the clipboard also on non-Windows platforms
    You can paste text from the clipboard into the console or other edit fields with Shift+Insert
  • Explicit support for Right Ctrl, Alt and Shift keys
    (can be bound to different actions than their left counterparts)
  • Added in_grabKeyboard CVar to make sure dhewm3 gets all keyboard input
    Prevents the Windows-key or Alt-Tab or whatever from taking focus from the game
  • Added in_ignoreConsoleKey - if set to 1, the console is only opened with Shift+Esc, and the "console key" (that key between Esc, 1 and Tab) can be freely bound to an action (and its char can be typed in the console without closing it).
  • Added (SDL2-only) "auto" option for in_kbd: When not disabling the console key, dhewm3 will try to automatically detect it if in_kbd is set to "auto" (now default)
• Reworked mouse-input and -grabbing code, using absolute mouse mode in fullscreen GUIs (except for the PDA, because it's implemented weirdly).
  This made releasing the mouse in the main menu possible, as now the ingame cursor is at the same position as the system cursor.
• s_alReverbGain CVar to reduce EFX reverb effect intensity (#365)
• Pause (looped) sounds when entering menu (#330)
• Fixes for looped sounds (#390)
• Replace libjpeg with stb_image and libogg/libvorbis(file) with stb_vorbis
  • Now the only required external dependencies should be OpenAL, SDL, zlib and optionally libCURL (and of course the C and C++ runtimes)
• (Optionally) use libbacktrace on non-Windows platforms for more useful backtraces in case of crashes (usually linked statically)
• Fixed a deadlock (freeze) on Windows when printing messages from another thread
• Fixed endless loop (game locking up at startup) if graphics settings couldn't be applied (#386)
• Fixed some warnings and uninitialized variables (thanks turol!)
• Work around dmap bug caused by GCC using FMA "optimizations" (#147)
• Prevent dhewm3 from being run as root on Unix-like systems to improve security
• Replaced most usages of strncpy() with something safer to prevent buffer overflows (remaining cases should be safe).
  • Just a precaution, I don't know if any of them could actually be exploited, but there were some compiler warnings in newer GCC versions.
• Console output is now logged to dhewm3log.txt (last log is renamed to dhewm3log-old.txt)
  • On Windows it's in My Documents/My Games/dhewm3/
  • On Mac it's in $HOME/Library/Application Support/dhewm3/
  • On other Unix-like systems like Linux it's in $XDG_DATA_HOME/dhewm3/ (usually $HOME/.local/share/dhewm3/)
• Improved compatibility with Wayland (#426)
• Work around assertion in AlphaLabs4 due to "ride_of_death" yeeting the dead "monster_zsec_shotgun_12" into the void (#409)
• Support loading some mods known to need fs_game_base d3xp via Mods menu (currently, The Lost Mission and LibreCoop d3xp are supported)
• Disable assertion in idSampleDecoderLocal::DecodeOGG() that triggered when starting a new Classic Doom3 game (#461)

1.5.1 (2021-03-14)

• The (Windows-only) integrated editing tools of Doom3 are back!
  • They can only be built with non-Express versions of Visual Studio (tested Community Editions of VS2013 and VS2017) and can be disabled via CMake
  • Official dhewm3 Windows binaries are built with tools enabled, of course.
  • Only supports 32bit builds, because in contrast to the rest of dhewm3's code, the tool code is not 64bit compatible at all.
  • Based on Code from the dhewm3 branch of SteelStorm2, thanks to Motorsep for donating that code!
  • Has some bugfixes over the state in Doom3 1.3.1, like selecting a material in the Particle Editor doesn't break the viewport of the game any more.
  • Thanks to Tommy Hanusa for testing and reporting some issues (that were subsequently fixed)!
• Update savegame format (see #303 and #344)
  • old savegames should still work, but new savegames can't be loaded with older versions of dhewm3!
• Uploaded updated builds of Mod DLLs (esp. Dentonmod should run a lot more stable now).
  Added Mod DLLs of LibreCoop and The Lost Mission.
  See https://dhewm3.org/mods.html for more details.
• dhewm3 now supports the Doom3 Demo gamedata
  • See here for installation instructions
  • This is based on Gabriel Cuvillier's code for D3Wasm, which ports dhewm3 to web browsers, thanks!
• Create the game window on the display the cursor is currently on (when using more than one display)
• Added r_fullscreenDesktop CVar to set if fullscreen mode should be "classic" or "Desktop" which means a borderless window at current desktop resolution
• Fullscreen modes that are not at the current desktop resolution should work better now
  • including nvidia DSR / AMD VSR; for that you might have to use dhewm3_notools.exe, as DSR/VSR seem to be incompatible with applications that use MFC (the GUI framework used for the Doom3 tools like the D3Radiant)
• Several sound-related bugfixes:
  • Lags in starting to play a sound which for example caused the machinegun or plasmagun sounds to stutter have been eliminated (#141)
  • Trying to reset disconnected OpenAL devices, this esp. helps with display audio on Intel GPUs on Windows, when switching to fullscreen (#209)
  • Looping .wav sounds with leadin now work (#291)
  • The game still works if no sound devices are available at all (#292)
  • Make "idSoundCache: error unloading data from OpenAL hardware buffer" a Warning instead of an Error so it doesn't terminate game (by Corey O'Connor, #235)
• Restore "Carmack's Reverse" Z-Fail stencil shadows; use glStencilOpSeparate() if available
  • That bloody patent finally expired last October: https://patents.google.com/patent/US6384822B1/en
  • This neither seems to make a visual nor performance difference on any hardware I tried (including Raspberry Pi 4), so this is mostly out of principle
  • Based on Code by Leith Bade and Pat Raynor.
  • The r_useCarmacksReverse and r_useStencilOpSeparate CVars allow switching both things on/off for comparison
• New CVar g_hitEffect: If set to 0, the player camera damage effects (like double-vision and extreme tilt) when being hit are disabled (by dobosken, #279).
• (On Windows) stdout.txt and stderr.txt are not saved next to the binary anymore, but in My Documents/My Games/dhewm3/, like save games, because the binary dir might not be writable and dhewm3 wouldn't start properly then
• Fix lingering messages in HUD after loading savegame
  • Sometimes the "Game saved..." message didn't go away after loading a savegame (when having saved while it still was showing from last save)
• Fixed clipping bug in delta1 which sometimes occured and made climbing some ladders impossible (#328)
• Improve compatibility with some custom scripts ("t->c->value.argSize == func->parmTotal" Assertion; see #303)
• Registering multiplayer servers at id's master-server fixed, so they can be found in the multiplayer menu (by Stradex, #293)
• Support for reproducible builds by setting the CMake option REPRODUCIBLE_BUILD.
• Should build on recent versions of macOS, also on Apple Silicon (thanks Dave Nicolson and Petter Uvesten).
• Proper handling of paths with dots in directory names (#299, #301)
  • Some string functions that are intended to find/cut off/replace/... file extensions did cut off the whole path at dots..
  • Especially fixes loading and saving maps from such paths in the builtin D3Radiant level editor
• idFileSystemLocal::ListMods() doesn't search / or C:\ anymore (it did so if one of the paths, like fs_cdpath, was empty)
• Don't use translation in Autosave filenames (#305)
  • In the Spanish translation all the Alpha Lab autosaves got the same name, now the autosave name is based on the mapname instead which is distinct

1.5.0 (2018-12-15)

• Support for some Mods via custom SDK: Classic Doom3, Fitz Packerton, HardQore2, Denton's Enhanced Doom3 and Rivensin.
  • See https://dhewm3.org/mods.html for more information.
  • This has also broken backwards compatibility with 1.4.x game DLLs, that's why this version will be 1.5.0 and not 1.4.2.
• Supports High DPI displays on Windows now
• Scale menus, fullscreen videos and the PDA to 4:3 (with black bars left/right) on
  widescreen displays so they don't look stretched/distorted. Can be disabled with r_scaleMenusTo43 0.
  No, this unfortunately can't be done for the HUD (except for the crosshair), because it also handles fullscreen effects (for example when receiving damage), and those would look bad with black/empty bars on left/right.
• Commandline option to display some help on supported commandline arguments: -h or --help or -help or /?
• (Experimental) uncapped framerate, enable by entering com_fixedTic -1 in the console (can be set back with com_fixedTic 0).
  (this turned out to be broken, see #261)
• Support for the AROS and OpenBSD operating systems
• Several bugfixes

1.4.1 (2016-06-19)

• Fixed some (kinda rare) crashes due to assertion errors, especially observed in the last boss fights of both doom3 and the Resurrection of Evil Addon.
• Improved compatibility with AZERTY keyboards (the row of keys with 1...9, 0 is now usable)
• Fixed a crash (at least on FreeBSD) when loading Resurrection of Evil's last level
• Compatibility with Microsoft Visual Studio 2015
• Video resolutions in menu now sorted, added 2880x1800
• Support for up to 8 mouse buttons (on Linux this needs SDL2 2.0.4 or newer to work)

1.4.0 (2015-10-09)

The first dhewm3 release. Changes compared to Doom3 1.3.1 as open sourced on 2011-11-22 (most work done by dhewg):

• Use CMake as build system instead of Visual Studio and XCode solutions and SCons etc
• Replaced lots of platform-specific code with libSDL
• Use OpenAL as only soundbackend on all platforms (instead of only on Windows)
  Ported EAX for sound effects to the cross-platform OpenAL EFX extension
• Made code 64bit compatible (except for Windows-only MFC-based tools, which were disabled because no free or at least no-cost compiler with MFC support was available at the time)
• Also made it compatible with the MinGW compiler
• Write savegames, configs, screenshots etc in user-specific directories instead of installation directory on all platforms
• Fixed lots of bugs and compiler warnings
• Removed support for binary .pk4's, only support loading .dll/.so/.dylib for game-code (mods) directly
• Support (and automatically detect) arbitrary aspect ratios
• Support more resolutions, inject them into the settings menu
• Open ingame-console with Shift+Esc (=> works with all keyboard layouts)
• Most probably much more I forgot...
