Path tracing in games is no longer a futuristic promise; it’s here, and CAPCOM has made one of its most ambitious moves yet by integrating it into the RE Engine for Resident Evil Requiem and PRAGMATA. The result is visually stunning, but the tradeoff—performance that pushes even high-end hardware to its limits—raises questions about who will actually experience these improvements in real-world play.
The RE Engine’s path tracing isn’t just a visual upgrade. It introduces three key techniques: Screen-Space Environment Reflection (SER), Reflective Shadow Termination with Importance Sampling (ReSTIR GI), and DLSS Residual Rendering (RR). Together, they aim to deliver cinematic lighting without sacrificing interactivity—but the reality is more nuanced.
Performance isn’t just a matter of raw FPS. CAPCOM’s implementation shows that path tracing adds significant overhead, even with NVIDIA’s DLSS RR. On an RTX 4090, Resident Evil Requiem runs at around 35–40 FPS in path-traced mode, a far cry from the 60+ FPS achievable without it. That gap widens on lower-end GPUs, where the experience can feel more like a tech demo than an accessible game.
The real question is whether this is a strategic move for CAPCOM’s ecosystem or just another layer of complexity for developers and players. The RE Engine was already designed with modularity in mind, allowing future games to adopt path tracing incrementally. But if the goal is to make these techniques mainstream, the current implementation suggests that only those with top-tier hardware—and patience—will see the full potential.
Key Specs
- Path Tracing Techniques: SER (Screen-Space Environment Reflection), ReSTIR GI (Reflective Shadow Termination with Importance Sampling), DLSS RR (Residual Rendering).
- Performance Impact: ~35–40 FPS on RTX 4090 in path-traced mode; significant drop-off on lower-end GPUs.
- Hardware Requirements: NVIDIA RTX 40 series or better for optimal results.
The RE Engine’s path tracing isn’t just about pushing pixels—it’s about redefining what real-time lighting can achieve. But the cost is steep, and the experience remains a luxury for those with high-end setups. For the rest, it’s a glimpse of the future, not yet a reality.
Looking ahead, CAPCOM’s roadmap suggests more games will adopt these techniques, but the question remains: Will they prioritize performance or visual fidelity? If the trend continues, path tracing in mainstream games may still be years away from becoming truly accessible. For now, it’s a milestone, not a revolution.
