Pragmata’s, Resident Evil Requiem’s RE Engine Path Tracing Integration Explained in Hour-Long Video

by

Just before the release of Pragmata and a couple of months after Resident Evil Requiem, Capcom and Nvidia shared a detailed, hour-long presentation from GDC explaining how they integrated path tracing into the RE Engine. The presentation, featuring Capcom’s Hitoshi Mishima and Nvidia’s Calvin Hsu, is available to watch in video form below.

According to Mishima and Hsu, Capcom developers Kenta Nakamoto and Kosuke Nabata spent a year and a half integrating path tracing directly into the RE Engine. The system relies on Nvidia’s DLSS Ray Reconstruction to reduce noise and maintain smooth performance. However, this reliance means path tracing in both Resident Evil Requiem and Pragmata will only work on Nvidia RTX graphics cards.

The developers made several design choices to efficiently use streaming ray tracing, which focuses path tracing on the most important light sources. These included adjusting brightness to avoid dark spots with spotlights, using a simpler lighting model (Lambertian diffuse with single-lobe specular) instead of a more complex one, skipping image-based lighting, and adding surfaces that emit their own light.

Capcom used DLSS Ray Reconstruction to improve image quality by correcting visual issues like blurry or frosty surfaces, problems with how light interacted with materials like skin, and distortions on things like glass and raindrops.

Before their launch, both Resident Evil Requiem and Pragmata had trailers demonstrating how path tracing – a technology for more realistic lighting – could dramatically improve visuals on PC. This was achieved using RTX graphics cards. The trailers also highlighted other RTX features, like DLSS 4 with Multi Frame Generation, which can significantly increase frame rates by creating extra frames.

Both Resident Evil Requiem and Pragmata have received good reviews, showing that Capcom continues to deliver high-quality games. Resident Evil Requiem is currently available on PC, PlayStation 5, Xbox Series X/S, and Nintendo Switch 2. Pragmata will be released later this week, on April 17th, for the same platforms.

While you’re anticipating the release of Pragmata, check out the latest trailer! It shows the main character, Hugh, using a variety of weapons with his android companion, Diana, as they explore a location called The Cradle. Hugh starts with a basic weapon called the Grip Gun, which functions like a pistol. But when he needs more firepower, he can switch to weapons like the Shockwave Blaster to take on several enemies at once.

Keep in mind that while Hugh’s weapons are important, you’ll also need to use Diana’s hacking skills. Enemies in Pragmata are heavily armored, and Diana can lower their defenses to make them vulnerable.
