QGIS was born on Linux. It remains the most "performant" OS for the software because of lower system overhead. Ubuntu and Fedora users generally see the fastest processing times for heavy geoprocessing tasks. Performance Pro-Tips for 2025
Let’s break down the official requirements, recommended specs, and pro tips for 2024–2025.
3D map views and point cloud processing require significantly more graphics power.
Then, check your OpenGL version: glxinfo | grep "OpenGL version" (Linux/macOS) or use GPU Caps Viewer (Windows).
Allow 20–30 GB for QGIS itself + temporary files (often stored in C:\Users\...\AppData\Local\Temp ). Temporary raster processing can eat 50+ GB.
