Blender 5.3 Is Out: Vulkan by Default, a Compositor Effects Stack and Gaussian Splats

Blender 5.3 is out. The free 3D suite landed on November 10, 2026, and this one has something for almost everyone, from faster viewports to a reworked compositor to the first steps toward Gaussian splat support.

Here is a list of the features added to Blender for VFX, motion graphics or just for fun.

Vulkan is now the default

Vulkan is now the default graphics backend on Windows and Linux. (Windows on ARM is the exception.) Vulkan is the modern replacement for OpenGL, and the payoff is a smoother viewport in many scenes. Developer benchmarks on an NVIDIA RTX card showed the Sponza test scene jumping from about 437 to 493 frames per second compared with Blender 5.2.

Blender also lowered the minimum to Vulkan 1.1, so older graphics cards have a better shot at running it. Mac users stay on Metal, as before.

A DLSS denoiser for the viewport

NVIDIA RTX owners get a new DLSS-based denoiser for the Cycles viewport. It cleans up the noisy preview faster by upscaling and reusing samples from earlier frames, so you see a clean image sooner while you light a scene. You need NVIDIA driver 620 or newer.

The compositor gets an effects stack

The biggest change for compositing is a new effects stack. You can now pile up compositor effects the same way you stack modifiers on a model, with each effect built as its own node group that feeds the next one. It lives in a new Compositor tab in the Properties panel.

That makes it much easier to build a reusable look, like a glow, a grade and a lens effect, and drop it on any shot. Other compositor upgrades include:

• Playback caching in the interactive compositor, with GPU playback up to 2x faster.
• On-screen gizmos for the Translate, Scale and Transform nodes.
• Classic bloom is back as a built-in asset, for anyone who missed the old EEVEE Bloom look.
• A much faster Kuwahara node, the painterly filter, especially on Apple GPUs.
• Many Geometry Nodes math and utility nodes now work in the compositor too.

One heads up: new files start with a plain Group Input to Group Output node tree instead of a Render Layers node. Old files are not affected, but it can throw you the first time.

Gaussian splats arrive, sort of

Blender 5.3 can now import Gaussian splats through both its USD importer and its glTF importer. Splats are the photo-real 3D captures that studios and phone apps are using more and more. If you are new to them, our guide What Is 3D Gaussian Splatting? explains the idea in plain English.

Keep expectations in check. The release notes cover importing splats, not rendering them in Cycles or EEVEE. Still, getting the data into Blender is the first step, and it shows where things are heading.

Better glass, panoramic cameras and more

• Cycles adds dispersion to the Principled BSDF, so glass and gems can split light into rainbow edges.
• Rough anisotropic glass now works in Cycles, for brushed or stretched highlights on transparent materials.
• EEVEE supports seven panoramic camera types, including equirectangular and fisheye, which helps anyone making 360 video or dome content.
• New EEVEE lighting nodes aimed at toon shading and iridescent effects.
• Geometry Nodes gains volume tools such as Rasterize Points and a Poisson Solver, useful for smoke and fluid style effects.
• A new USD Collection Importer keeps a USD file linked to a collection, plus better Alembic import and export for pipeline work.

Things that might look different

If your scene uses the Sky Texture with the sun disc turned on, EEVEE renders will look different because the sun disc now adds real light. Turn the sun disc off to get the old look back. Grease Pencil also drops its Frame Duration option, and old files are converted when you open them.

Should you upgrade?

For most people, yes. Blender is free and installs side by side with older versions, so you can test 5.3 without touching your current setup. If you are mid-project, finish on the version you started with, then move over. Compositors should try the new effects stack first. It is the change most likely to speed up your daily work.
