About / EasyHDR features and requirements

HDR photo processing software

Requirement Description
Operating system
Screen resolution At least 1024x600 (at standard dpi scaling, at higher DPI larger minimum screen resolution is required).

It is strongly advised to work with higher resolutions, including 4K with HighDPI (i.e. 200% scale).
Memory At least 4GB of RAM
CPU Intel CPU with SSE3 instruction set (basically all CPUs manufactured after 2006).
Multicore CPUs are required for better performance.
Apple M1 supported with Rosetta 2 on macOS.
Hard Disk EasyHDR uses temporary files that are created on the hard disk. The default storage location is the system's TEMP folder, but it can be selected in the Program Options. At least 1-2 GB of free space is recommended. SSD drive is also recommended for better performance.
