The workstation requirements for g-Viewer are listed below.

Operating system

• Windows: Windows 11, 64-bit.
• Linux: Red Hat Enterprise Linux 8, 9 or 10, 64-bit, or a compatible distribution of the same version (Rocky Linux, AlmaLinux, Oracle Linux).
• macOS: macOS 26 or later on a Mac with Apple Silicon (M-series processor). Intel Macs are not supported.

CPU

• Any 64-bit CPU; a multi-core CPU is recommended. g-Viewer uses all available cores, so more cores give better performance.

RAM

• 4 GB minimum.
• Recommended: twice the size of the seismic data you load.

Graphics

• Vulkan is the default 3D renderer. The 3D view needs a graphics card and driver with Vulkan 1.0 support; current NVIDIA, AMD and Intel drivers include it. Keep the graphics driver up to date.
• macOS: the 3D view always uses Vulkan through MoltenVK, which is installed with g-Viewer; no extra software is needed.
• Without a usable graphics card (virtual machine, remote desktop, faulty driver), untick Use GPU 3D rendering in Tools > Options. The 3D view then renders on the CPU with the bundled SwiftShader driver; it works everywhere but is slower.
• OpenGL is deprecated. It is still available as 3D renderer = OpenGL in Tools > Options (Windows and Linux; applied after a restart) and needs OpenGL 4.5. If Vulkan cannot start, g-Viewer switches to OpenGL by itself and shows a notice.

Disk

• SSD storage is recommended for prestack seismic data.
• An HDD is sufficient for the rest of the project data.

Licence

• A licence key (USB dongle or network licence) needs the Sentinel LDK runtime. A network licence needs a current version of the runtime on the workstation. See Licensing.
• The free version runs without a licence key.

Seg-D and LAS data

SEG-D and LAS files have no extra requirements. To use Sync folder for continuous shooting, the SEG-D folder must be reachable from the workstation.
