Best Render Farm for Lumion 4K Rendering: GPU Requirements & Cost
The best render farm for Lumion 4K rendering is iRender, offering dedicated RTX 4090 servers with 24GB VRAM at ~$8.20/hour. Lumion 4K rendering at “Ultra” quality requires a minimum of 16GB VRAM — which rules out older GPUs like the GTX 1070 (8GB) and RTX 2060 (6GB). On iRender’s RTX 4090, a 4K exterior still renders in 8–15 minutes, costing approximately $1.50–2.50. A 4K animation (2 min, 30fps) costs $3–6. Traditional SaaS render farms (RebusFarm, GarageFarm, Fox Renderfarm) cannot run Lumion at any resolution because Lumion requires a dedicated GPU with real-time desktop access.
| GPU | VRAM | 4K Still (Ultra) | 4K Walkthrough (2 min) | Available On |
| RTX 4090 ⭐ | 24GB | 8–15 min | 20–40 min | iRender (~$8.20/hr), Xesktop |
| RTX 3080 | 10GB | 18–30 min ⚠️ | 50–90 min ⚠️ | Xesktop (~$10/hr) |
| RTX 3060 (local) | 12GB | 22–35 min | 1.5–3 hours | Local workstation |
| GTX 1070 (local) | 8GB | 35–55 min ⚠️ | 3–6 hours ⚠️ | Local workstation |
| RTX 2060 (local) | 6GB | 25–40 min ⚠️ | 2–4 hours ⚠️ | Local (high VRAM risk) |
How Much VRAM Does Lumion 4K Actually Need?
Lumion’s VRAM usage at 4K depends heavily on scene complexity. Based on our testing: a simple interior (< 2,000 objects) uses approximately 8–10GB VRAM at 4K Ultra — manageable on an RTX 3060 (12GB). A complex exterior (5,000+ objects with foliage and water) uses 14–20GB VRAM, requiring at minimum an RTX 4090 (24GB). A large masterplan (10,000+ objects, cityscape) can spike to 22–26GB VRAM, pushing even the RTX 4090 close to its 24GB ceiling.
For masterplan scenes that approach the 24GB limit, we recommend switching from “Ultra” to “High” quality — this reduces VRAM usage by approximately 15–20% with minimal visible quality loss in most architectural contexts. Alternatively, use Lumion’s layer visibility to hide distant objects that won’t appear in the final frame.
Is the RTX 3080 on Xesktop Good Enough for Lumion 4K?
For simpler 4K scenes only. Xesktop offers RTX 3080 servers (10GB VRAM) at ~$10/hour — cheaper per hour than their RTX 4090 option ($14/hour). The RTX 3080 handles 4K interiors and simple exterior scenes well, but its 10GB VRAM becomes a bottleneck for complex exteriors (5,000+ objects), where you risk render crashes without warning.
For reliable 4K exterior work, the RTX 4090 on iRender at $8.20/hour is actually both cheaper and more capable than Xesktop’s RTX 3080. Xesktop’s RTX 4090 at $14/hour provides the same GPU but costs 70% more. This makes iRender the clear value leader for Lumion 4K rendering.
