to retina factor
What does the retina factor do?
The retina factor controls the pixel density at which images are displayed on high-resolution screens. A higher value makes images appear sharper on Retina displays but also increases file size.
By default, the neo Optimize plugin uses a retina factor of 1.5x to enhance rendering of small text, icons and image details on Retina displays. In the Pro version you can set the retina factor individually and compare it directly in the preview.

Clear cache
When should I clear the neo Optimize cache?Under normal operation it is not necessary to clear the neo Optimize cache. The clear cache button can be helpful if you want to remove old image variants after many tests or tidy up after major changes to image sizes in the page builder. Optimized images are then automatically regenerated as soon as they are needed again in the frontend.
If you change image quality, the retina factor or other optimization settings, neo Optimize will automatically create new optimized images. When an image is deleted from the WordPress media library, the associated cache files are automatically removed. Even optimized images that were renamed with neo Rename are automatically cleaned up.
The Clear Cache button is therefore intended primarily as a reset and cleanup function.
