Doom 64 RT — Native Linux (beta 1)

Native Linux build of Doom 64: Ray Traced — no Wine, no Proton.

Install

1. Download doom64-rt-linux-beta.1-x86_64.AppImage, chmod +x it.
2. Make a game/ directory next to it, and drop in:
   • the whole of Doom 64: Retribution v1.5 (WAD, brightmaps, soundfont),
   • D64MUS.PK3 from the OGG music pack v1.3,
   • optionally doom2.wad (Steam/GOG installs are found automatically; D64RT_IWAD overrides).
3. Run it. ./doom64-rt-*.AppImage check verifies the setup without launching; ./doom64-rt-*.AppImage 13 warps to MAP13.

Requirements

A GPU with hardware ray tracing and Vulkan. DLSS (Super Resolution) is bundled and auto-selected on NVIDIA; FSR2 elsewhere (D64RT_UPSCALER=dlss|fsr|none overrides). Config and logs live in ~/.config/doom64-rt/.

Provenance

Built from acolomba/gzdoom-rt doom64-rt-linux and acolomba/RTGL doom64-rt-linux — upstream jlrouzies-fr/doom64-rt's doom64-rt branches merged with the native Linux port. Upstream's Windows release is unaffected.

Known caveats

• Tested on one machine (NVIDIA, X11/XWayland). The FSR2 path and AMD/Intel GPUs are untested on Linux.
• DLSS Ray Reconstruction ships off, as upstream ships it (alpha).
• The Unseen Evil monster pack needs a local build from upstream's tools (art is not redistributable) and is auto-detected if present in mods/.
