SIGGRAPH 2025 has handed by in Vancouver in a blur of groundbreaking advances in AI and robotics (and a tribute to 30 years of Toy Story). However highlights for a lot of 3D artists had been a few demos of latest options coming to Blender, a free and open-source program that is change into on the of the most effective 3D modelling software program choices.
Blender teased the introduction of Nvidia-powered real-time path tracing through its DLSS upscaling tech, and customers are enthusiastic about how a lot much less irritating that would make previewing work within the viewport on Cycles.
DLSS stands for Deep Studying Tremendous Sampling. It is a tech developed by the GPU large Nvidia that makes use of AI to upscale lower-resolution photos, permitting for greater resolutions and higher visible constancy with out the hit on efficiency.

The addition of DLSS denoising as an possibility within the Cycles render engine in Blender takes a a lot decrease decision viewport and upscales it with AI to appear like the traditional picture utilizing much less computing energy than regular strategies. It is also optimised to deal with low ray counts in video video games.
As demonstrated within the video above shared by Andrew Value, AKA Blender Guru, the result’s that previews within the viewport are a lot smoother to work together in. Though the instrument ends in ghosting, it is a lot simpler to dwell with than the frustration that comes from a sluggish viewport, making pre-vis extra viable or much less highly effective computer systems (though you may nonetheless want a Nvidia RTX graphics card).
One other SIGGRAPH unique Blender demo was Nvidia’s DLSS denoiser for Cycles. It made shifting across the viewport really feel as easy as EEVEE! Loopy stuff. One other video under pic.twitter.com/qlbZAh7tJbAugust 15, 2025
“It made shifting across the viewport really feel as easy as EEVEE!” one SIGGRAPH attendee enthused on X after viewing the demo. “It did have ghosting throughout animation and glass objects had been flickery, identical to DLSS in video games, however for previewing scenes it’s unbelievable. Night time and day distinction in interactivity within the viewport.”
There was no clarification of when the DLSS denoiser might be coming to Blende, however some persons are already questioning if we’ll see extra animated motion pictures opting being made utilizing blender because of the pre-vis being higher (see our information to the most effective animation software program for the alternate options).
The most recent steady launch is Blender 4.5 LTS, which was launched on 15 July. Blender 5.0 is presently in Alpha testing till 1 October, 2025.
