Here are the official system requirements for 3Dsurvey v4 (the photogrammetry software). Please note that these are general guidelines, and the actual requirements can vary significantly depending on the size of your projects (number of images) and the desired processing speed.

As of my last update, 3Dsurvey is a Windows-only application. Here are the typical specifications recommended by the developer:

 Minimum Requirements
For small projects (e.g., <100 images) and basic processing.

- Operating System: Windows 10 (64-bit)
- Processor (CPU): Intel Core i5 or equivalent
- Memory (RAM): 16 GB
- Graphics Card (GPU): DirectX 11 compatible graphics card (e.g., NVIDIA GTX 900 series)
- Storage: Solid State Drive (SSD) with at least 10 GB free space (for project files and cache)

 Recommended Requirements
For standard projects (e.g., 100–1000 images) and good performance.

- Operating System: Windows 10 / Windows 11 (64-bit)
- Processor (CPU): Intel Core i7 or i9 (or AMD Ryzen 7/9) – Higher clock speeds are beneficial.
- Memory (RAM): 32 GB or 64 GB
- Graphics Card (GPU): NVIDIA GeForce RTX 2070 or higher (or NVIDIA RTX A-series) with at least 8 GB VRAM
    - Note: While 3Dsurvey uses the CPU heavily for core calculations, a good GPU is essential for the 3D viewport smoothness and texture generation.
- Storage: NVMe SSD (M.2 drive) with ample free space (50+ GB).

 High-End / Professional Requirements
For large mapping projects (thousands of images) and maximum speed.

- Operating System: Windows 11 (64-bit)
- Processor (CPU): Intel Core i9 or AMD Ryzen 9 (or Intel Xeon / AMD Threadripper for workstations)
- Memory (RAM): 64 GB or 128 GB
- Graphics Card (GPU): NVIDIA RTX 3080 / 4080 or NVIDIA RTX A4000/A5000 (Professional cards are stable but consumer cards often offer better price/performance)
- Storage: High-speed NVMe RAID configuration.

 Key Considerations for 3Dsurvey v4

1.  CPU over GPU: Unlike some competitors (like ContextCapture or RealityCapture which leverage GPU for processing), 3Dsurvey relies heavily on the CPU for the core 3D reconstruction and point cloud generation. Therefore, investing in a CPU with a high clock speed (GHz) and a high core count is usually more beneficial than an extremely expensive GPU.
2.  RAM is Critical: Photogrammetry is memory-intensive. If you run out of RAM, processing will slow down dramatically or fail. 32 GB is the realistic minimum for professional work; 64 GB is highly recommended for drone mapping with several hundred images.
3.  SSD Speed: The software reads and writes temporary files constantly. An NVMe SSD (as opposed to a SATA SSD or HDD) makes a noticeable difference in processing speed.

For the absolute latest specifications (especially if they have added GPU-based features in recent updates), it is always best to check the official 3Dsurvey website or contact their support directly.
