Classic Doom With Ray Tracing Looks Amazing

Classic Doom With Ray Tracing Looks Amazing

OK, before we begin, you won’t be able to play this version of Doom on a pregnancy test or cash register. But whatever, the original Doom with ray tracing is so cool that I can forgive that one drawback.

Announced yesterday on April Fools’ Day, this new visual mod for the original 1993 release of Doom ain’t a joke. Created by modder sultim-t, this mod adds real-time path tracing to the PrBoom source port of Doom. It currently supports the first three episodes of the classic shooter and dramatically changes the way Doom looks, letting you play the old-timer with incredible, modern lighting.

Installing this new ray tracing mod for Doom is fairly simple. You’ll need an original Doom.wad file to run this, which considering how old and cheap the game is, you likely already have one kicking around somewhere on your computer. Then you just download the mod for PrBoom, a modern Doom source port and you are off the races. Or should I say… RAY-ces. (I shouldn’t. I’m very sorry that I did.)

Sultim-t explains on the mod’s download page that this only works for Nvidia GPUs and they are willing to help someone get this working on Linux.

This ain’t the first time we’ve seen a classic Id shooter get the raytracing treatment. In 2019, Nvidia partnered with Id to create Quake II RTX, a version of the classic shooter that also utilised real-time ray tracing tech.

I really enjoy the way Doom and Quake look with fancy real-time lighting. The simple textures and geometry of these classic shooters still hold up in 2022, but now the improved lighting is able to improve the atmosphere of these old-school digital worlds. Doom in particular can look downright scary at times using this new mod.

Of course, as mentioned already, you’ll need a decently powerful PC to run these games with ray tracing enabled as this tech is very resource-demanding and needs modern, fairly high-end GPUs to even work at all.

  • Ok ok…..No apologies……at least you tried… and yes Quake II ray traced is great looking…looks like doom will be the same.697.

  • It doesn’t look amazing at all. Every light source is too bright and there’s so much bloom you’d think Doomguy’s helmet is a thick layer of vaseline sandwiched between two sheets of glass.

    • Don’t base judgement on the video, it doesn’t do it justice.
      For some reason bloom looks like it’s turned up high in the video.
      On default I thought it was perfectly fine, but you can turn it down/off if you choose.
      I think they also tweaked bloom in one of the releases, so that might also be why I think it looks better ingame.

      Overall the lighting is pretty good, but I agree some of the light sources are too bright and could be tweaked for better look;
      – I don’t know what is up with the barrels, I think it might just be when they are to close to walls it makes them look insanely bright, but when away from a wall they are fine.
      – Weapon flashes/projectiles/enemy projectiles could all be toned down though for more ambience imo. You can tweak the muzzle flash at least so it’s not bad.
      – Tall torches seem very bright and blow out some areas.

      In most levels the overall ambience, lighting, and bloom (on default) was great. Of course the game was never made with this type of lighting in mind so there are going to be spots where it doesn’t work perfectly. Some levels have a few spots that are not so good (ie overly bright tall torches), and 1 or 2 levels that are just gross; honestly they are terrible in the original too though, so don’t hold that against the RT mod.

      There is some RT noise and artifacts here and there.
      Personally after playing, I like it and would choose to play with it on if I have the option.

  • Doom was never played on a pregnancy test iirc – it was just a small LCD installed in the shell of an empty pregnancy test connected to an EXTERNAL mcu that ran the game.
