Best Render Farm for Architecture: iRender vs CapCloud for Korean Architects

When Is CapCloud the Better Choice?

Language matters more than people admit. When something goes wrong at midnight before a deadline — a render crashes, a license doesn’t activate, a file won’t upload — troubleshooting in your native language is not a luxury, it’s a necessity. CapCloud’s Korean customer support via KakaoTalk resolves issues faster for Korean-speaking architects than any English-only support channel. Their local server infrastructure also means Parsec latency under 10ms from Seoul — noticeable when navigating Lumion’s viewport interactively.

For Korean firms that process expenses in Won and need Korean tax invoices (세금계산서), CapCloud’s billing integration with Korean accounting systems eliminates the currency conversion and international transaction complications that come with iRender’s USD pricing.

When Is iRender the Better Choice for Korean Architects?

When GPU power and price are the priority. iRender consistently offers RTX 4090 — the highest-performance single GPU available for arch-viz. CapCloud’s GPU inventory varies; depending on availability, you might get an RTX 3080 or RTX 3090 instead of a 4090. The RTX 4090 renders 30–50% faster than an RTX 3080 and has 50% more VRAM (24GB vs 16GB for the 3080). For complex Lumion exteriors that push VRAM limits, this hardware gap matters.

iRender’s latency from Korea (connecting to Vietnam-based servers) is approximately 40–80ms via Parsec — slightly higher than CapCloud’s ~10ms but still usable for rendering work. For file uploads, Korea’s internet infrastructure is excellent (100 Mbps+ average), so transfer speeds to either provider are fast. Korean architects who are comfortable with English and prioritize per-hour value tend to choose iRender; those who prioritize Korean-language support and seamless local experience choose CapCloud.

Frequently Asked Questions

1. Can Korean architects use iRender without English proficiency?

iRender’s interface and support are primarily in English. Basic navigation — booting a server, connecting via Parsec, installing software — follows visual steps that don’t require fluent English. However, troubleshooting issues (scene errors, license problems) requires communicating in English via live chat. If this is a barrier, CapCloud’s Korean KakaoTalk support eliminates it entirely. Some Korean architects start with CapCloud, then switch to iRender once they’re comfortable with the cloud rendering workflow.

2. Is the latency difference between CapCloud and iRender noticeable?

For rendering (clicking Render and waiting): no — latency doesn’t affect render speed. For interactive viewport navigation (orbiting in Lumion, adjusting Enscape materials): slightly. CapCloud’s ~10ms from Seoul feels like a local PC. iRender’s ~40–80ms from Korea adds a subtle delay when moving the mouse. Most architects describe iRender’s latency as “workable but not perfect.” For interactive design sessions where viewport responsiveness matters, CapCloud has a genuine edge.

3. Are there other render farm options popular in Korea?

Beyond CapCloud and iRender, Korean architects commonly discuss these options on Quasarzone and Naver Cafe: Xesktop (~$10–14/hour, IaaS alternative), RebusFarm (SaaS, V-Ray/Corona batch), and Fox Renderfarm (SaaS, budget V-Ray batch with Chinese/Asian infrastructure). For Lumion and Enscape users in Korea, the realistic IaaS choices are CapCloud (local) and iRender (best GPU power per dollar). Both have active Korean user communities.
