NVIDIA RTX Remix 1.6 Adds DLSS 5 and Path Tracing for Minecraft Java

NVIDIA released RTX Remix 1.6 on October 23, 2026, adding DLSS 5, new frame-generation options and experimental path tracing for Minecraft Java Edition. The update also brings new tools for modders and Windows on Arm support, while the Minecraft feature is still an early beta with limited compatibility and possible visual or performance issues.

A new Fabric mod brings RTX Remix path tracing to Minecraft Java Edition 1.21.1 through an API-based rendering pipeline. NVIDIA created a PBR texture resource pack for the mod and worked with BlockWorks on a demonstration map. The free mod is in early beta, and its compatibility with other mods is limited.

RTX Remix 1.6 integrates DLSS 5 3D-Guided Neural Rendering, with controls for choosing between three models, adjusting highlights and volumetric effects, and applying masks to individual materials. The technology has also appeared in fan projects based on Fallout 4 and Mirror's Edge. The update adds 5× and 6× Multi Frame Generation options on supported hardware, as well as a faster performance mode that can slightly reduce image quality. Generated frames do not make the game itself run faster or reduce latency like real frames do.

The update replaces RTX Remix's legacy AI asset tools with ComfyUI 2.0 workflows for generating and processing textures and meshes. It also lets modders connect AI agents to Remix tools. Windows on Arm runtime support is included, along with public ARM64 and ARM64EC build artifacts.

NVIDIA says a Windows driver optimization for AMD graphics cards improved performance by about 20% in community measurements: from 53 to 63 FPS on driver 26.6.4. RTX Remix 1.6 can be downloaded from the project's GitHub page or through the NVIDIA App. The minimum NVIDIA driver version required is 616.92.
