| Feature | Integrated GPU | Entry Dedicated | Mid-Range Dedicated | |---|---|---|---| | | Fine | Very smooth | Instant | | Large raster display | Sluggish | Smooth | Very smooth | | 3D Map View | Not recommended (or very slow) | Playable | Excellent | | Terrain (DEM) hillshading | Slow | Acceptable | Fast | | Point cloud (LAS/LAZ) | Unusable | Slow (< 50M points) | Good (< 200M points) |
Working with orthophotos, DEMs, moderate point clouds, dozens of vector layers, and 3D visualization. 4. Performance Requirements (Heavy / Enterprise workloads) For large-scale projects: statewide parcel data, high-resolution satellite mosaics (>20GB), real-time GPS tracking, or batch geoprocessing. qgis requirements
| Component | Recommended | Why it matters | |---|---|---| | | 4-core, 3.0+ GHz (Intel i5/i7 or AMD Ryzen 5/7) | Faster geometry calculations, reprojection, and rendering. | | RAM | 16 GB (8 GB absolute minimum for professional use) | QGIS loads data into RAM. Large vector/raster files need memory. | | Storage | SSD (NVMe preferred) with 500 GB free | GIS involves many small file reads (SSD is 10x faster than HDD). | | Graphics | Dedicated GPU with 2–4 GB VRAM (NVIDIA GTX 1050 or higher / AMD equivalent) | Smooth pan/zoom, 3D map view, and terrain rendering. | | Display | 1920 x 1080 (Full HD) or higher | QGIS has many panels (Browser, Layers, Processing Toolbox). | | Page file / Swap | 1.5x RAM size | Prevent crashes when processing large datasets. | | Feature | Integrated GPU | Entry Dedicated
| OS | Minimum Version | Architecture | Notes | |---|---|---|---| | | Windows 10 (64-bit) | x64 | Windows 7/8 no longer supported. Windows 11 works perfectly. | | macOS | macOS 11 (Big Sur) | Apple Silicon (M1/M2/M3) & Intel (x86_64) | Native Apple Silicon support since QGIS 3.30. | | Linux | Ubuntu 20.04 / Debian 11 / Fedora 36 | 64-bit | Installed via apt , dnf , or Flatpak/Snap. | | Android/iOS | Not officially supported | N/A | Use "QField" (mobile version of QGIS) instead. | Important: 32-bit operating systems are no longer supported after QGIS 3.0. 2. Minimum System Requirements (Runs, but slowly) Use this as a baseline for small projects (e.g., a few shapefiles, small rasters <100MB, basic editing). | Component | Recommended | Why it matters
QGIS is a free, open-source Geographic Information System. Because it is constantly updated, its demands on hardware have increased, but it remains less demanding than proprietary software like ArcGIS Pro.
