Earth Volumetric Studio (EVS) runs on most modern PCs and does not require special hardware.
Minimum Requirements
| Hardware Item | Minimum Requirement |
|---|---|
| Operating System | 64-bit Windows 11 |
| RAM | 8 GB minimum. 16-64 GB strongly recommended for production work. |
| Processor | Any modern processor. Eight or more cores recommended. |
| Monitor | 1920 x 1080 minimum. 4K or higher is desirable. |
Recommendations
Memory (RAM)
How much memory you need depends on your projects and data. While 8 GB is the minimum, we strongly recommend 16-64 GB or more for any new system. DDR5 memory is much faster than DDR4 and will noticeably speed up EVS calculations.
Biggest Performance Impact: RAM Speed
Of all hardware choices, faster RAM has the greatest impact on how quickly EVS processes data. Many of EVS’s calculations depend heavily on memory speed. Upgrading to DDR5 memory can dramatically reduce processing times — often more than a faster processor alone. If you are buying a new system, prioritize RAM speed and capacity above all else.
Graphics Card
A good graphics card makes 3D rotations and interactions smoother and faster. EVS works with most graphics cards, but very old or low-end cards may not support all visual features.
- NVIDIA GeForce cards offer the best performance for the price. We use NVIDIA cards in our own systems and recommend them for most users.
- NVIDIA Quadro and other professional cards perform extremely well if budget is not a constraint.
- EVS can use your graphics card’s processing power (GPU compute via CUDA) to speed up calculations. This works best on higher-end gaming cards and professional graphics cards.
Processor
EVS runs on any modern processor, and a faster processor means faster results. Eight or more cores are highly recommended, as many EVS tasks run faster with more cores.
Monitor
A good monitor makes it easier to work effectively for extended periods. We strongly recommend at least 1920 x 1080 resolution. 4K or higher is desirable and provides significantly more workspace for complex models.
Operating System & IT Requirements
EVS is compatible with 64-bit Windows 11. The C Tech Universal License Server is additionally supported on Windows Server 2022 and Windows Server 2025.
