- preload next image to cache 690ms
only after preloading is done, the next image can be displayed.
The most expensive part is instanciating a QImage(myimage) object with 690ms, which includes reading the file from the harddrive. Downscaling to screensize and converting to GL format takes around 70ms. At least on my setup, downscaling by CPU is still faster than copying a 20Mb texture to video mem and downscaling by GPU.
