Summary

  • Nvidia's RTX Remix Logic lets modders add modern visual features to games without access to a title's source code or engine.
  • The feature offers a node-based, no-code editor that makes it straightforward to add modern lighting, weather, materials, and path-traced volumetrics to mods for older games.
  • RTX Remix Logic support includes 165 classic PC games at launch.

Following its announcement at CES 2026 earlier this month, Nvidia has publicly released RTX Remix Logic, a new feature that allows modders to dynamically trigger graphics effects in direct response to real-time in-game events. RTX Remix Logic is able to accomplish this without access to a game's source code or engine, making it ideal for adding more modern visual features to older titles.

Nvidia says that there are 30 in-game events that can be triggered with RTX Remix Logic, including the following:

  • Player state — Camera position, camera zoom, player world coordinates
  • World bounding boxes — Indoor/outdoor detection, region-specific triggers
  • Object state — Any tracked object's position, visibility, and proximity to the player
  • Time flow v In-game time of day, elapsed real-time
  • Input — Specific key presses by the player

These triggers are capable of changing visual features like lighting conditions, weather systems, material properties, post-processing effects, and path-traced volumetrics. Nvidia says that you don't need to be a professional coder to add RTX Remix Logic to mods either. The feature includes a no-code node-based interface that allows modders to easily drag and drop visuals that represent various triggers and actions.

In the video above, Nvidia shows off RTX Remix Logic in action by triggering a Ravenhold multiverse with various lighting and weather effects in Half-Life 2 RTX.

Over 165 classic PC games currently support RTX Remix Logic

According to Nvidia, at launch 165 classic PC games support RTX Remix Logic. Support for more titles will likely be added in the coming weeks.

Alongside RTX Remix Logic, Nvidia has also confirmed that DLSS (Deep Learning Super Sampling) is coming to Half Sword, a physics-focused medieval combat simulator hitting Steam Early Access soon. DLSS Super Resolution is also making its way to Code Vein II, alongside DLSS 4.5 hitting controversial PvP shooter Highguard.

RTX Remix Logic is available through a Nvidia app update now.
