Digital Foundry analysis details RT usage on consoles and PC
A update bringing Ray Tracing in order to Doom Eternal on PCs and new generation consoles arrived last week. While on PC the game received DLSS and RT support, O PlayStation 5 e Xbox Series X received higher resolutions, high frame rates and the own Ray Tracing, which was the main new feature for the game.
Eternal Doom now has reflexes in time real on surfaces such as water, glass, metal, plastic and polished wood. Unlike consoles, the PC still has the advantage of DLSS, making it possible to take advantage of the implementation of Ray Tracing from the RTX 2060. Remembering that video cards AMD Radeon RX 6000 support the RT of NVIDIA, but without the possibility of using DLSS.
O Digital Foundry brought an in-depth analysis of the NVIDIA technology implementation to Eternal Doom. According to the analysis, the game uses many materials that help to enrich the reflections, such as metals and shiny plastics, even though more opaque materials still benefit from the technique. Digital Foundry’s Alex Battaglia says that RT made the game far more dynamic compared to the game’s standard graphics engine “to the point where the animated environment reflects perfectly on the appropriate surfaces.”

Alex says that even shot particles, like the BFG gun, are seen in reflections on any nearby surface along with other dynamic elements of the scene. The reflection in the glass suffers, even, with the distortion that that glass can have. If the glass is rounded, you can see the distortion by stretching what is being reflected. “Ray Tracing is applied to each pixel, so even small glass objects like vials of life will show detailed reflections if you look closely,” says Alex Battaglia.

Digital Foundry mentions that the “screen-space” reflections, which are part of the game’s engine, are on top of the effects generated by Ray Tracing, which brings some inaccuracy compared to the use of “pure” RT, but by on the other hand, it brings increased performance.
Consoles handle RT in dynamic 1800p, Which is equivalent to average quality of reflections on PC. “A GeForce RTX 2060 using DLSS in performance quality climbing 1800p from 900p looks pretty better than both console versions and it doesn’t degrade the image in dynamic resolution the way it does with the PlayStation 5 and Xbox Series X”.
