At GTC 2022, NVIDIA announced an RTX Mod for Valve’s classic puzzle game, Portal. Portal RTX promises to feature full ray tracing effects, and will support DLSS 3.0. Furthermore, NVIDIA revealed the RTX Remix Modding Tools which modders can use in order to enhance older games with full ray tracing effects.
Needless to say that the RTX Remix Modding Tools is something that will benefit A LOT of games. Thanks to these tools, we can finally get full ray tracing effects in classic games like Doom 3, Half-Life, Unreal, The Elder Scrolls III: Morrowind and more.
Before jumping to conclusions, the RTX Remix Modding Tools are not similar to the Reshade Ray Tracing effects that numerous PC gamers have been using. We are talking here about full and proper ray tracing effects.
As NVIDIA CEO’s Jensen Huang explained, modders will have to capture a game into a USD. Then, you can use the modding tools in order to create a Ray Tracing Mod, and export the RTX renderer. RTX Remix also uses AI techniques in order to overhaul/upscale all of the textures, as well as an AI model to convert materials to have physically accurate properties.
We really can’t wait to see what modders will be able to achieve with RTX Remix. Essentially, we’ll be getting free full Ray Tracing remasters of our favorite games, and that definitely has me excited!

It looks amazing!
But… Damn, it’s Portal, a century old game that’s been used as a tech demo to hell and back… Yeah, I’m sick of it.
PD: DON’T make dream of Morrowind with raytracing!!! ?
Nvidia remix is definitely interesting. Wonder if the game devs of their game need to allow remix to be used?
Because capturing a scene into USD sounds exactly like asset ripping.
gotta push that dlss hype to the dumb masses. portal was a game that left me absolutely cold and unimpressed, if i want to play a puzzle game i can crank out the games box from under the bed. as uninteresting as quake 2 rtx was. yawn nvidia, yaaawn.
From all of the game advertised as having ray tracing, my attention always going to old games enhanced with this effect rather than newer games. Quake II RTX, DOOM RTX, Minecraft RT,etc are way more interesting than any of modern game nowadays because I can trully see the difference Ray Tracing can make compared to modern games
