Caveats

Memory requirements
Please read the blog entry on maximizing memory efficiency
Differences between the preview and the output image
The color-managed preview in RawTherapee is (and has always been) based on image data in the Working Space profile. Although the actual preview is rendered using a monitor profile (or sRGB profile, if the monitor profile is not specified), it does not reflect the Output Profile & Output Gamma settings. This can lead to a slightly different output rendering when Working Space profile and Output Space profiles are not the same. You should set them to the same values to ensure the preview accurately reflects the final rendered output.
