Lumion 2026 System Requirements: CPU, GPU, RAM, and Why It Won't Run on a Mac

Lumion publishes three tiers — Minimum, Recommended, and High-end — and scores the graphics card by benchmark rather than by naming a chip family. That is a different approach from a vendor like Autodesk, which names a DirectX version and a Shader Model. Lumion instead quotes a PassMark G3DMark score, which measures a card's general 3D performance regardless of brand or generation.

Minimum: entry-level

A GPU scoring G3DMark 8,000 or higher — Lumion names the NVIDIA GeForce GTX 1060, Quadro K6000, or AMD Radeon RX 580 as reference points — 6 GB or more of video memory, 16 GB of system RAM, and a CPU with a single-thread CPUMark of 2,200 or higher. Lumion's own copy is unusually blunt about this tier: "This configuration is not recommended, as it can only handle simple projects," and it advises against buying new hardware to this spec.

Recommended: complex projects

G3DMark 14,000 or higher (an RTX 3060, Quadro RTX 2000 ADA, or Radeon RX 6700 XT clears it), 10 GB or more of VRAM, 32 GB of RAM, and a CPUMark of 2,600 or higher. Lumion sizes this tier for a complex single building with detailed interiors, or a small park or city block reconstructed from OpenStreetMap data.

High-end: masterplans and animation

G3DMark 22,000 or higher — an RTX 3090, RTX A6000, or Radeon RX 6800 XT — with 16 GB or more of VRAM, 64 GB of RAM, and a CPUMark of 3,000 or higher. This is the tier Lumion attaches to masterplans, stadiums, and multi-floor buildings using fine-detail nature and 3D grass. There is no published tier above it.

Lumion sells a second product with a completely different hardware floor, and conflating the two is the most common way to misread this specification. Lumion Viewis a lightweight plugin for SketchUp, Revit, and ArchiCAD built for early-stage design review, not final rendering — and it runs on hardware that would not clear Lumion Pro's Minimum tier.

The graphics line is the tell. Lumion Pro explicitly rules out integrated graphics — its own hardware guide says the card "needs to be a dedicated system and not onboard graphics." Lumion View asks for the opposite: a ray-tracing-capable integrated GPU, the kind built into a current Intel Core Ultra or AMD Ryzen chip with no discrete card at all. Two products, two documents, and a search for "Lumion system requirements" can land on either one depending on which page ranks that day.

Lumion 2026 accepts 64-bit Windows 10 (version 2004, Build 19041) or newer, or Windows 11 (version 24H2, Build 26100) or newer. Lumion adds a caveat rather than a hard cutoff: its system requirements page notes that "Windows 10 has reached end of life support and only receives critical security updates," and recommends migrating to Windows 11 — but it has not removed Windows 10 from the supported list the way some CAD vendors have for their newest release.

The Windows 10 floor itself has not moved since Lumion 2023. Lumion's knowledge base states that "Lumion 2023 and newer requires Windows 10 version 2004 or newer, or preferably Windows 11." What has moved is which Windows 11 build counts as preferred — 21H2 (Build 22000) for Lumion 2023 through 2025, 24H2 (Build 26100) for 2026 — which tracks Microsoft's own release cadence rather than anything Lumion changed on its end.

There is no Mac version of Lumion Pro

There is no macOS build of Lumion Pro and there never has been. Lumion's support team answers the question directly in its knowledge base: "Can you install Lumion on OSX? No. Lumion cannot be installed on OSX, and there are no plans to make Lumion available on OSX." Unlike a modeller such as Revit, which at least publishes a supported way to run its Windows build inside a virtual machine on a Mac, Lumion closes that door too.

Parallels and VMware Fusion are explicitly unsupported

The same article states it without hedging: "Parallels and VMware Fusion for OSX are not supported and will cause crashes, glitches and License Key lock-ups." That is a specific, named failure mode — not a generic "unsupported configuration" disclaimer — and it rules out the exact workaround that makes Revit usable on a Mac. A Boot Camp install, where the Mac fully boots into Windows rather than running it in a virtual machine, is the only route Lumion support has ever pointed to for Intel Macs, and Boot Camp does not exist on Apple silicon at all.

The exception: Lumion View runs natively on Apple silicon

The one genuine exception is Lumion View for SketchUp, which ships a native Apple silicon build. It supports M2 Pro for rasterization, and M3 or M4 (Pro, Max, or Ultra) for both rasterization and ray tracing, alongside 16 GB of RAM and SketchUp 2025 or newer. That covers early-stage, in-viewport visualization only — the moment a project needs Lumion Pro's asset library, animation tools, or final-image rendering, the Mac path ends.

Why Lumion scores GPUs instead of naming a spec floor

Lumion's graphics requirement is a moving target by design. Rather than naming a DirectX version or a list of certified cards, it quotes a PassMark G3DMarkscore — a single number PassMark computes from thousands of submitted benchmark runs across GPU generations and vendors. The practical effect is that Lumion's requirement stays current without Lumion having to republish a card list every time NVIDIA or AMD releases a new generation; you just look up your card's current G3DMark score and compare it to the tier.

Lumion is also unusually direct that this has to be a dedicated card. Its 2026 hardware guide calls the graphics card "the single most important component for Lumion" and states it "needs to be a dedicated system and not onboard graphics." That rules out the integrated GPUs in most non-gaming laptops for Lumion Pro, even though those same chips are exactly what Lumion View is built to run on.

Integrated graphics: where Intel Arc fits

One qualifier moved in the 2026 guide: Intel graphics are now an accepted exception, but only from a specific point onward. The note reads "Intel: A series or newer B series; A580 or B580 or better cards only". That is Intel's discrete Arc line, not the integrated graphics bundled into a standard laptop CPU — so "Intel graphics" on a spec sheet is not, by itself, enough to know whether a machine qualifies.

Which GPU to buy, by what you render

CPU

Lumion scores the CPU the same way it scores the GPU — a PassMark single-thread CPUMark, not a core count or a named family. 2,200 or higher clears Minimum (Lumion's example is a Ryzen 5 1600X or Core i7-4790S), 2,600 clears Recommended (Ryzen 5 3600, Core i5-8600), and 3,000 clears High-end (Ryzen 5 5500, Core i7-11700T). Every reference chip Lumion names is a mid-range part from its own tier, not a flagship — a signal that single-core speed, not raw core count, is what the application actually leans on while you edit a scene.

RAM

16 GB, 32 GB, or 64 GB, matched to the same three tiers. Unlike some CAD vendors, Lumion does not publish a formula tying RAM to project file size — the tiers are qualitative ("simple project" versus "ultra complex"), which makes RAM the hardest line in this specification to size against a specific job before you've already loaded it.

Storage

105 GB of free disk space, and Lumion is specific about where: on whichever drive holds your Windows user account and Documents folder, not just wherever you choose to install the application. That figure is identical across all three tiers — Minimum, Recommended, and High-end all ask for the same 105 GB — and Lumion recommends a SATA3 SSD or NVMe drive at the Recommended tier and above.

Power supply

Lumion is one of the few applications in this cluster to publish a power-supply requirement at all: an 80+ gold-rated unit with sufficient wattage for the graphics card installed, at every tier. It is a reasonable line for a vendor whose entire product is built around keeping a discrete GPU under sustained real-time load, and an easy one to miss if you are pricing a build against the RAM and GPU rows alone.

Internet

An internet connection is required for the PC running Lumion, full stop — Lumion does not describe an offline licensing mode. The requirement is stated identically for Lumion Pro and Lumion View.

Lumion switched from numbered releases (Lumion 12 was the last) to year-named releases starting with Lumion 2023, which rebuilt the render engine around ray tracing. That makes the version table below closer in shape to Autodesk's than to Blender's — rows are calendar years, not point releases.

The standout fact is what did notchange. Lumion's own 2026 hardware guide states it plainly: "there are no changes in hardware requirements for Lumion 2026 from those for Lumion 2025/2024/2023/Lumion 12." The G3DMark, CPUMark, and RAM tiers on this page have held for roughly five years and two full render-engine rewrites. The only line that has moved release over release is the recommended Windows 11 build — 21H2 for 2023 through 2025, 24H2 for 2026— which tracks Microsoft's update calendar rather than anything in Lumion itself.

One consequence: a machine bought to run Lumion 2023 still meets the published spec for Lumion 2026. There is no equivalent here to Revit dropping Windows 10 outright, or Blender raising its GPU floor at a major version. The reason to upgrade hardware for Lumion is a bigger project, not a newer release.

Lumion does not endorse specific machines, and neither does this page. Because Lumion Pro requires a dedicated GPU at every tier, a laptop bought for it needs a real mobile discrete card, not the integrated graphics that satisfy Lumion View. Price bands below are approximate street prices for a Windows 11 laptop at the time of writing and move constantly; the specifications are the durable part.

Budget tier

Roughly $1,300 to $1,800. A discrete mobile GPU clearing G3DMark 8,000 (an RTX 3050/4050-class card), 16 GB of RAM, and a 512 GB SSD or larger — the 105 GB storage requirement eats more than a third of a 256 GB drive before you install anything else. This meets Lumion's Minimum tier, which is Lumion's own words "not recommended" for a new purchase, and is realistic for a student or a first machine used mostly for learning the interface.

Mid tier

Roughly $2,000 to $2,800. A mobile RTX 4060 or 4070-class GPU (10 GB or more of VRAM, clearing G3DMark 14,000), 32 GB of RAM, and a 1 TB SSD. This is Lumion's Recommended tier and covers a single detailed building or a small landscape comfortably.

Pro tier

$3,200 and up, and often a desktop rather than a laptop once you're at this tier, since a mobile GPU clearing G3DMark 22,000 is rare and thermally constrained. 16 GB or more of VRAM, 64 GB of RAM, and fast NVMe storage. Justified by masterplan-scale scenes, animation output, or fine-detail nature assets — not by wanting the biggest number on a spec sheet.

• Lumion runs, but drops frames or looks worse than expected. Almost always a GPU below the G3DMark figure for the project's actual complexity, not a broken setting. Check the card's current G3DMark score against the tier — scores shift slightly as PassMark's sample size grows, so a card bought two years ago may have moved between tiers on paper without changing at all in hardware.
• Lumion crashes or the license locks up on a Mac. Expected if it's running inside Parallels Desktop or VMware Fusion. Lumion's own support documentation names this exact failure mode and does not offer a fix, because the configuration itself is unsupported.
• Installation fails or Lumion won't launch on a laptop with Intel graphics. Check whether the chip is a genuine Arc discrete GPU (A-series or newer B-series, A580/B580 or better) rather than the integrated graphics bundled into the CPU. Only the former is accepted for Lumion Pro.
• Installer or project loading fails with a disk-space error. Lumion's 105 GB figure applies to the drive holding the Windows user account and Documents folder specifically, not wherever the application itself was installed — a common trap on machines with a small system SSD and a larger secondary drive.
• Textures or nature assets look blurry or take a long time to appear. Usually VRAM pressure rather than a driver problem — Lumion's own note states 4K rasterization and 1080p ray tracing each need at least 8 GB of graphics memory on their own, on top of whatever the scene itself already occupies.

• Keep GPU drivers current.Lumion's own hardware guidance repeats this at every tier — it is the single most-cited fix in its own documentation, not a generic suggestion.
• Buy on G3DMark and CPUMark, not on a model name you recognize. A card or chip that looks impressive by reputation can still sit below the tier you need; the benchmark score is the number Lumion actually checks against.
• Reserve ray tracing for final output, not live editing. Rasterization is the lighter mode of the two and is what the Minimum and Recommended tiers are sized around; switching to ray tracing only when composing a final Photo or Movie keeps day-to-day editing responsive on modest hardware.
• Give the 105 GB its own drive if you can. Keeping the Windows user account and Documents folder on a dedicated SSD, separate from a smaller system drive, avoids the installation and loading failures that show up when that specific volume runs low.
• Never route around the Mac limitation with Parallels or VMware. Lumion's own documentation is specific about the failure mode here, and there is no configuration of either product that Act-3D supports.

Every requirement on this page exists because Lumion renders in real time on your own GPU. Move that step off the machine and the GPU floor, the VRAM figure, and the Windows requirement all go with it.

This is the specific case where Render a House closes a gap Lumion cannot close on its own: it runs in a browser, so it needs no dedicated GPU, no G3DMark score, and no Windows install — including on the Mac that Lumion Pro will never support, in any configuration, at any specification. Upload a flat image of a Lumion scene, a floor plan, or a sketch and it generates a photorealistic concept image without asking what card is inside the machine you're using. It's free to start, with 3 renders a day, and paid plans start at $39/mo.

The clearest use case is a mixed-hardware team: a firm running Lumion on Windows workstations for walkthroughs and animation, where a Mac-based designer or a client on a laptop without a dedicated GPU still needs to produce or review a still concept image without waiting for the Lumion machine to free up.

What browser rendering cannot do

It is not a replacement for Lumion, and treating it as one wastes time on the wrong task. Browser rendering has no real-time viewport — no walkthrough, no live camera path, no scrubbing a timeline the way Lumion's Movie mode does. It holds no scene file, no asset library, and no LiveSync connection back to a CAD model, so a change in your model or floor plan means generating again rather than watching an open scene update. It will not produce an animation, a VR export, or a deterministic frame you can re-render identically twice.

What it is good at is the single concept image, generated in seconds from a flat input, for the moment in a project when standing up a full real-time scene is more setup than the deliverable is worth.
