SIGGRAPH 2025 in Vancouver showcased a wave of innovation in AI and robotics, but for 3D artists, the spotlight shone brightly on upcoming features for Blender, the popular free and open-source 3D creation suite. Specifically, demonstrations of Nvidia-powered real-time path tracing, leveraging DLSS upscaling technology, generated significant excitement.
Understanding DLSS and its Impact on Blender
DLSS, or Deep Learning Super sampling, is an AI-driven technology developed by Nvidia. It works by rendering images at a lower resolution and then intelligently upscaling them, resulting in visuals that appear high-resolution without the performance cost.This is particularly beneficial in demanding applications like 3D rendering.
The integration of DLSS denoising within Blender’s Cycles render engine is a game-changer. Instead of rendering the viewport at full resolution – a process that can strain even powerful computers – Blender can now utilize DLSS to upscale a lower-resolution render with AI, significantly reducing computational load. this optimization is rooted in techniques originally developed for video games, where maintaining high frame rates is paramount.
Smoother Pre-Visualization and Accessibility
Early demonstrations,including a video shared by Andrew Price (known as Blender Guru),revealed a dramatic betterment in viewport fluidity. Attendees at SIGGRAPH 2025 reported that the viewport felt “as smooth as EEVEE,” Blender’s real-time rendering engine. One attendee shared on X (formerly Twitter): “It made moving around the viewport feel as smooth as EEVEE! Crazy stuff…Night and day difference in interactivity in the viewport.” While some ghosting artifacts were observed during animation and with glass objects – a common characteristic of DLSS – the overall improvement in responsiveness was considered a major step forward.

What’s on the Horizon for Blender?
Currently, Blender 4.5 LTS, released on July 15, is the latest stable version. Blender 5.0 is currently in Alpha testing, with a planned release date of October 1, 2025. While a specific timeline for the DLSS integration hasn’t been announced, the buzz surrounding the SIGGRAPH 2025 demo suggests it’s a high priority for the blender progress team. The potential for smoother workflows and increased accessibility makes this a highly anticipated addition to the software.
