    Ive saw the differences while setting my old high quality wallpapers (1920x 1200) as background.Being used with the same wallpapers for some long I instanly noticed the differences.
    I have the latest drivers

    so here is a capture while runing winodows 7:

    and with windows 8:


    Attachment 1726

    Oh crap I cannot insert links to the actual size pictures nor to isert bigger pictures than these

    the diffrence its more proeminent on the fullscreen size



    Another change Ive spoted is that my desktop does not respond everytime when I click refresh. Only on 5th- 6th try.

    Hi StefaNafetS,

    Thanks for posting. I dont notice this tiny difference on my windows 8. Anyway, this is not a big problem. You may ignore it.

    well I have to disagree... we are staring at our desktops all day and this is quite an issue of windows 8 appearance. Im sure the new look of the new windows was the main aspect people upgraded to it.

    Anyway I found the solution
    It seems this is the way windows 8 deals with non PNG formats like JPG or BMP. So you need to convert them to PNG to no loose quality. Tough I cannot figured how to do these in case of wallpapers that come with themes.

    If a moderator/ administrator could edit the thread title the way I modified it in the original post.

    I strongly recommend to move this somewhere to be broadly visible as is an importan aspect of windows 8 appearance.!!!

    I think I found why this happens with windows 8
    Im quoting someone from other win8 forum:

    "It is possible that windows compresses ALL file formats for wallpapers as when I go to C:\Users\USER_NAME\AppData\Roaming\Microsoft\Windo ws\Themes\CachedFiles my wallpaper despite now being a PNG file has been changed to a JPEG file of a much smaller size. So windows is still compressing the PNG files but the quality isn't as poor. It is likely that when someone uses a JPEG as a wallpaper, because of the already poor quality of the jpeg it gets further compressed and a low quality wallpaper results (kinda like a double effect). HOWEVER, I used to use JPEGs in windows 7 and they weren't compressed so much. SO maybe in windows 8, MS has decided to increase compression of the cached file/transcoded wallpaper?"
