Doom 64 RT v0.1.21 — Native Linux (beta 2)

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

What's new

Synced with upstream v0.1.21 (beta 1 was v0.1.20):

• Options > Quality > Texture filtering: Nearest / Bilinear / N64 three-point (rt_texture_filter); the GL "Texture filter mode" row drives it too.
• Intel integrated GPUs (unified memory) no longer fail at start on memory types -- untested on Linux.

Install

1. Download doom64-rt-v0.1.21-linux-beta.2-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/.
