Dear D5 Render Support Team,
I hope you are doing well.
I am writing to report a significant performance issue I am experiencing with a large D5 Render project when transferring it between different devices.
The project consists of:
- A SketchUp model of approximately 30 MB
- One 3ds Max building model that I import once , then duplicate around 130 times directly inside D5 Render
I import the full scene into D5 Render once and then continue working on it without re-importing.
On my main workstation (RTX 3060), the project is heavy but works relatively well.
Loading times are reasonable, navigation is smooth, and hiding objects improves performance as expected.
However, when I transfer the same D5 project file to other devices equipped with:
- RTX 4070
- RTX 3070
- RTX 4060 Ti
the performance becomes extremely poor.
The file does open, but it takes around 1 to 1.5 hours to load, and the workflow becomes very slow and almost unusable.
I also tried hiding all objects in the scene except the main SketchUp model, but the file size, loading time, and overall performance remain very heavy on those devices.
What is confusing is that performing the exact same steps on my RTX 3060 workstation results in much better performance.
This leads me to believe the issue may not be related only to GPU power, but possibly to:
- How D5 handles duplicated models internally (instances vs full copies)
- Asset or texture caching
- Project data paths when moving projects between machines
- Project packaging or optimization behavior
I would appreciate your guidance on:
- Whether duplicating a model many times inside D5 is treated as instancing or full duplication
- Why performance differs so drastically between machines with similar or stronger GPUs
- Recommended steps before transferring a D5 project to another device
- Best practices for handling very large scenes to ensure consistent performance across multiple workstations
Thank you very much for your time and support.
I look forward to your advice.
Best regards,
Mo Hamed
