AMD’s Senior Graphics R&D Engineer, Dihara Wijetunga, is currently working on a Path Tracing Mod for Return to Castle Wolfenstein. Similarly to Quake 2 RTX, Doom Path Tracing and Serious Sam Path Tracing, this mod will introduce full real-time path tracing effects to the game.
According to the developer, this mod is still in an early development stage. As such, don’t expect to be playing it anytime soon. Still, Wijetunga does plan to release this project once it’s complete so that everyone can enjoy it.
In order to showcase the graphical improvements that Path Tracing brings to the table, Wijetunga shared the following comparison screenshots. These screenshots are from an early build, and do not represent the quality of the final version. Nevertheless, they can give you an idea of what you can expect from it.
Wolf PT is based on iortcw with a custom DX12 backend. However, they may add support for the Vulkan API as a secondary backend.
Enjoy and stay tuned for more!

Awesome news. One of my favorite single-player games of all time.
And THE BEST Wolfenstein game till date.
The dude doing the RT mod also said that he’ll keep some of the fixed lightings to retain some of the Classic atmosphere.
So those initial screenshots shared are actually not final. Just first draft.
Man, the X-labs along with the crypt creeped me the f out when I was a kid. They still do to be honest. Such a strong atmosphere in this game.
IMO original atmosphere is ruined. I was expecting something better (like Quake 2 rtx or half life).
Quake 2 was an official Nvidia conversion done by team of professionals.
This is early footage from a 1-man project.
He’s not done. He was talking about it on twitter. He said he still has a sh*t ton to tweak.
you ok buddy? it’s just videogames here.
so guess that’s a no.
Is it bad that I prefer the look of thr original game in all the screenshots shown except maybe the second one?
Same, new sh*t looks horrendous imho
NOIIICE!
RTCW is a classic masterpiece FPS, and without a doubt the best Wolfenstein game! And someone who knows what they doin making a RT mod…looking forward to it!
Apart from the first screenshot where electric bolt is emitting too muich light ruining the scene, all the other screenshots look great imo.
rtcw is a classic, take a chill pill this game isn’t even woke.
You don’t mind that it’s about killing your people?
