Blender 5.3 has shipped with the ability to import 3D Gaussian Splats from PLY, SPZ, and glTF files, plus support for Nvidia's DLSS 4.5 Ray Reconstruction as a new denoiser and compatibility with Nvidia RTX Spark devices. The update also makes Vulkan the default graphics backend on Windows (excluding ARM) and Linux, replacing OpenGL, and adds dispersion support to the Principled BSDF shader node in Cycles.
Nvidia's DLSS 4.5 introduces several model presets—K, M, and L—accessible through the app under Graphics > Global Settings > DLSS Override. Preset K targets high-end GPUs for maximum image quality, preset M suits mid-range cards like the RTX 4070 by upscaling from 1080p, and preset L is aimed at older RTX 20 and 30 Series cards, upscaling from 720p for better performance at some cost to image stability.
Nvidia has updated Ray Reconstruction, its AI denoiser-upscaler for ray tracing, to the second-generation transformer architecture used in DLSS 4.5 Super Resolution. The company says the new model handles 35% more compute and 20% more parameters than before, improving image quality and reducing ray-tracing artifacts with little to no performance cost. GeForce RTX owners can access the update immediately.
