Which version/release of Photoshop?

They have made changes that effect how photos look at different zoom values.

Does your computer have a graphics card that supports OpenGL?

Basically unless you are viewing the photo at 100%; i.e. one pixel in the photo equates to one pixel on the screen, then the software/hardware is doing some interpolating/resizing which will cause an apparent loss in sharpness. Depending on the exact software/hardware you are using this can either work well or not. Some zoom values, like 50% or 25% are easy, some are more difficult. Use windows' built in photo viewer to view a sharp photo at like 16% size to see just how unsharp a good photo can be made to look.

For those that don't know what i.e. means, viewing a photo at 100% means one photo pixel is the same size as 1 screen display pixel.
