Path Tracing Implementation in DOOM: The Dark Ages Took 6 Months, Says id Software Developer on Future Tech Expansion

DOOM: The Dark Ages Embraces Path Tracing Technology

In a groundbreaking move for the gaming community, DOOM: The Dark Ages has become the sixth PC title to adopt real-time path tracing, following in the footsteps of notable games such as Cyberpunk 2077, Alan Wake 2, and Indiana Jones and the Great Circle. This advancement, which enhances visual fidelity, was made possible through a crucial update released on June 18, 2025, about a month after the game’s initial launch.

Significant Enhancements with Path Tracing

The update introduced path tracing along with NVIDIA’s DLSS Ray Reconstruction technology, elevating both the aesthetics and performance of the game. As a result, DOOM: The Dark Ages has established itself as a benchmark within the gaming industry, compelling developers to elevate their own graphical standards.

Insights from id Software

Recently, NVIDIA held a Q&A with Billy Khan, Director of Engine Technology at id Software. Khan noted that the team spent approximately six months integrating path tracing into the game, showcasing the studio’s commitment to adopting new technologies. He also expressed optimism about seeing more titles transition from basic ray tracing to the more advanced path tracing in the future.

The Future of Path Tracing and Game Development

According to Khan, path tracing is now a core component of the id Tech 8 engine, and the studio intends to continue exploring its potential. The adoption of path tracing will vary based on the specific requirements of individual games to ensure player value is maximized.

Potential for Enhanced Performance

The anticipated release of future AMD graphics cards, renowned for their optimized ray tracing capabilities, is expected to accelerate the adoption of this technology across the industry. Khan also highlighted the importance of NVIDIA’s Opacity Micro-Maps and Shader Execution Reordering, particularly their role in optimizing rendering in DOOM: The Dark Ages.

Optimizing Performance and Quality

For complex scenes requiring high performance, enhancing surface shading and transparency is vital. Techniques enabling GPUs to intelligently prioritize shading tasks and bypass unnecessary calculations lead to considerable speed improvements. The deployment of Opacity Micro-Map (OMM) and Shader Execution Reordering (SER) has been instrumental in achieving better optimization, as some of the most substantial performance gains in path tracing emerged from utilizing shader execution reordering.

DLSS Ray Reconstruction: A Game-Changer

Moreover, DLSS Ray Reconstruction has played a significant role in enhancing the visual experience. Khan stated,

“DLSS RR really helped surface all the amazing details enabled by path tracing.”
