NVIDIA RTX Spark launches October 16: Blender and ComfyUI updates

On October 13, NVIDIA announced updates for local AI and content creation software ahead of the RTX Spark laptops’ October 16 launch. According to a post on the company’s blog, the RTX Spark laptops—announced jointly by NVIDIA and Microsoft—will arrive with updates for Blender, ComfyUI and Adobe apps, as well as local AI tools.

What’s new for RTX Spark?

NVIDIA describes RTX Spark as a platform that combines the capabilities of a gaming PC, a creative workstation and a personal AI computer. According to the company, the system offers up to 128 GB of unified memory and 1 petaflop of AI compute performance. The blog post does not disclose pricing or sales details for Turkey.

Pre-launch updates also include tools for installing and securing local AI agents and enabling them to work with the cloud. NVIDIA says apps such as GitHub Copilot, Hermes, OpenClaw, Perplexity, Pi and WorkBuddy have been updated to make it easier to install local models on RTX Spark. The company also mentions the Switchyard library, which routes requests between local and cloud models.

Creative workflows in Blender and ComfyUI

The Blender 5.3 beta is gaining RTX Spark compatibility. NVIDIA says DLSS Ray Reconstruction support will be added to Blender in November, helping artists preview scenes in real time as they navigate them. The announcement therefore distinguishes between compatibility in the available beta and the ray-tracing feature arriving later.

In ComfyUI, new nodes for RTX Video Frame Generation and RTX Video HDR are now available. According to NVIDIA, Frame Generation can increase a video’s frame rate on GeForce RTX 40 Series and newer graphics cards, while the HDR tool converts standard dynamic range footage to HDR. EXR export also adds an option for color grading. In the company’s example, 1080p SDR video at 30 frames per second can be converted to HDR at 60 frames per second and exported as EXR.

Optimizations for RTX Spark in Adobe apps are set to roll out gradually. NVIDIA and Adobe say they are targeting up to 2x faster performance in some creative workflows in Photoshop, Premiere and Substance 3D. Beta optimizations for some AI features in Photoshop and Premiere are ready, while updates to Substance 3D Painter are expected later.

Impact on architecture and visualization workflows

These updates may be of interest to visualization teams working on rapid scene previews, texture creation and AI-assisted video processing. The arrival of DLSS Ray Reconstruction in Blender is intended to enable real-time previews while interacting with scenes in supported workflows. Improvements announced for Substance 3D Painter focus on texture-creation tasks such as processing high-resolution mesh maps and opening and saving large projects.

However, compatibility and availability timelines matter. The Blender DLSS feature is slated for November, while Adobe updates will roll out gradually. For ComfyUI’s frame-generation feature, NVIDIA specifies GeForce RTX 40 Series or newer graphics cards. Since pricing for the RTX Spark laptops has not been announced, it’s too early to compare their cost with existing workstations; product and local sales information will be needed.
