ACDSee Pro is still the King of speed. The commercial software has its selling point.
But I would like to see how fast FastPictureViewer is with GPU acceleration.
Hamana is designed for reading comics.
JPEGView is the one I recommend, fast, free and open source.
Unicode filenames and directories are no problem.
It also support some photo editing features, and can show EXIF data on top of photos.
The only features I missed are color manager, and lossless crop.
