Warning: there are some possible issues with Linux open source Radeon drive: older version can crash, if texture size exceeds resources and automatic down-sampling of texture can fail; very big ROIs or very many images may exceed limit of 65536 VBOs. Proprietary drivers don't have the issues. Anyway in most cases open source Radeon driver will work.
- hardware and recent drivers with OpenGL 3 support are required for some modules
- OpenGL modules may be disabled - if hardware was not detected or optionally
- min. 1 GB, recommended 8 GB, better 16 GB and more
- more swap is recommended
