Yesterday, the so-called Nostalgia Drive Team released the first work-in-progress build of Left 4 Dead RTX NDT. This is based on the previous work done by modder xoxor4d, which we covered earlier this year.
The Nostalgia Drive Team describes Left 4 Dead RTX NDT as a visual overhaul of Valve's classic co-op first-person shooter game released in 2009, rebuilt with the NVIDIA RTX Remix platform (which just got a major update last month, allowing modders to inject old games with enhanced fire and smoke effects through a path traced particle system). This fan-made visual revamp focuses specifically on the No Mercy campaign and reimagines its environments with high-resolution physically based rendering (PBR) materials, improved reflections, and manually recreated lighting to achieve a cinematic and atmospheric look.
Technical Highlights
- Full PBR material system
- Manually re-lit scenes (RTX Remix cannot capture native lights)
- Enhanced shadows, reflections, and surface roughness
- Upgraded materials for buildings, interiors, and props
- 4K texture rebuilds and improved normal maps
- Full RTX Remix runtime compatibility
You can download the WIP build of Left 4 Dead 2 RTX NDT, which weighs 7.15GB, from ModDB. However, the NTD team shared the following warnings and disclaimers:
This is not a complete remaster but a foundation for future RTX mods in terms of compatibility and visuals. Due to engine limitations and ongoing development, some assets may appear unfinished or darker.
Expect missing/dark skyboxes, rubber-like materials on some models, incomplete lighting setups, water surfaces that may look off, and CPU-heavy performance on animated meshes. Moreover, the renderer is currently forced to run single-threaded, Alpha foliage heavily impacts performance, software skinning causes CPU bottlenecks, and some effects are still unhandled or inaccurate.
If, on the other hand, you want to contribute to the project, the Nostalgia Drive Team seeks help in the following areas: materials, lighting, assets, and testing. Those interested in joining the team can contact the user Entity in the official RTX Remix Showcase Discord channel.
