A path traced mod of Doom has been released
Modder Sultim-t has released Doom Ray Traced, a mod that renders light effects into the 90s game. For example, the mod can illuminate rooms with the lava flowing through them, and demons have light and shadows.
The mod enables you to play the first three episodes of Doom 1, with custom shaders allowing real-time path tracing. Some players have also been able to run the mod with Doom 2, albeit with some inconsistencies.
Several versions of the mod have already been released by Sultim-t, with the first reducing bloom and adding optional two light bounces. A second update, released the following day, removed artefacts related to specularity.
To play the modded version of the game, you need to have an original Doom.wad file and the PrBoom source port. Two optional additional downloads are for ‘high-quality music’ and another for DLSS.
While the engine could support both Nvidia DLSS and AMD FSR, Sultim-t notes that the mod will only work on Nvidia GPUs for now. The modder also suggests that you check GPU compatibility on gpuinfo.
Fans who have already tried out the Doom mod have had mixed reactions, with some complaining about its quality. Given the rate at which Sultim-t has already iterated on the mod, you might expect several more of these teething issues to be ironed out in the future.
