DUDE 0.9.1

DUDE 0.9.1 — portable Linux binary + shader packaging fix

Point release of 0.9. If you use
the OpenGL 3.3 or Vulkan renderers, upgrade — 0.9's archives were missing the GLSL/
SPIR-V shaders, so those two backends rendered black on a clean install (the default
classic renderer was unaffected). Shaders are now embedded in the executable itself and
can't go missing.

Changed since 0.9

• Portable Linux binary: the 0.9 only worked with Arch linux and derivatives.
  Now built against glibc 2.34 with static C++ runtime and static shaderc —
  it should run out of the box on Ubuntu 22.04+, Debian 12+, Fedora, Arch,
  and the gaming distros (SteamOS 3, Bazzite, Nobara, CachyOS…). A current Vulkan
  loader is bundled as a fallback (lib/libvulkan.so.1). System requirements are just
  SDL2, OpenAL and libcurl from your distro.
• Shaders embedded in the binary (GL3 + Vulkan): a bare executable now renders on
  all three backends; base/shaders/ stays available as a modder override.
• Archives now include the PBR material tables, gamepad configs and the mod
  cvar-translation table that 0.9 was not bundled with.
• Runtime mod-ARB shader compilation now works on the Linux binary (static shaderc).
  (Still absent on Windows Vulkan — affected mod effects skip there.)

Setup (same as 0.9)

You need the original DOOM 3 / Resurrection of Evil game data (base/*.pk4,
d3xp/*.pk4) from your own copy (Steam/GOG classic, not the BFG Edition).

• Windows (64-bit): unzip and copy the contents of the dude-0.9.1-win64
  folder into your Doom 3 directory, next to base/ (the included pk4/config files
  merge into base/). Or run from anywhere with +set fs_basepath "C:\path\to\Doom 3".
• Linux (x86_64): untar and copy the contents into your Doom 3 directory the same
  way, run ./dude. may need to change the file to have execution permissions with
  "chmod +x dude"

Renderer selection: +set r_graphicsAPI opengl|opengl3|vulkan or the in-game menu.
Configs/saves live in ~/.local/share/dude (Linux) / Documents/My Games/dude (Windows).

Optional download: baked ambient-occlusion pack

dude-0.9.1-baked-ao.zip (~100 MB): precomputed per-material AO maps for subtle
contact shading on world surfaces, props and weapons. Extract into your Doom 3
directory the same way. Entirely optional.

DUDE 0.9

DUDE 0.9 — first binary release

DUDE is a Doom 3 engine fork (based on dhewm3) with
modernized OpenGL 3.3 and Vulkan 1.4 renderers, an opt-in enhancement suite, and
the beginnings of an RTX pipeline — while keeping the faithful classic look as the default.

Highlights

• Three selectable renderers: legacy OpenGL/ARB (faithful default), OpenGL 3.3 core, Vulkan 1.4
• Quality presets (Potato → Nightmare) in the classic System menu: shadow maps (Vogel PCF + sun),
  SSAO, HDR, PBR + SSR, parallax occlusion mapping, soft particles, SMAA/FXAA
• Vulkan-only: ray-traced sun shadows (r_rtSunShadows, needs an RT-capable GPU),
  AMD FSR2 anti-aliasing, GPU tessellation + skinning for characters, parallel level loading
• com_interpolate: render above 60 fps with the authentic 60 Hz game simulation
• Classic mod support: runtime ARB shader compilation on the new backends, cvar-translation shim

Requirements

You need the original DOOM 3 / Resurrection of Evil game data (base/*.pk4, d3xp/*.pk4)
from your own copy (Steam/GOG classic, not the BFG Edition). No game assets are included.

• Windows (64-bit): unzip dude-0.9-win64.zip and copy the contents of the
  dude-0.9-win64 folder into your Doom 3 directory, next to base/ (the included
  base/zz_dude_menu.pk4 — the DUDE main menu with its high-res logo — merges into your
  base/ folder). Alternatively run from anywhere with +set fs_basepath "C:\path\to\Doom 3".
  Vulkan needs current GPU drivers; ray-traced options need an RT-capable GPU.
• Linux (x86_64): untar and copy the contents into your Doom 3 directory the same
  way, run ./dude. Needs SDL2 and OpenAL installed (standard packages on any distro).

Configs, saves and screenshots live in the "dude folder": ~/.local/share/dude (Linux),
Documents/My Games/dude (Windows).

Optional download: baked ambient-occlusion pack

dude-0.9-baked-ao.zip contains precomputed per-material AO maps (z_baked_ao*.pk4,
~100 MB) generated by DUDE's offline AO baker — subtle contact shading on world
surfaces, props and weapons, applied through the engine's occlusion-maps path.
Extract it into your Doom 3 directory the same way (the pk4s land in base/).
Entirely optional; the engine works without it.

Known limitations

• Windows binaries are cross-compiled with mingw-w64 and are new — reports welcome.
• Custom/mod ARB shaders don't yet compile at runtime on the Windows Vulkan backend
  (they do on Linux, and on the OpenGL backends everywhere); affected mod effects skip.
• Sub-native FSR2 upscaling, RT shadows for local lights, and RT reflections are on the
  roadmap.
