You might have an advantage in creating your own PictureBox that inherits from the original. You can override the OnPaint and tweak the following parameters of the passed Graphics object:

private override OnPaint(object sender, PaintEventArgs e)
{
    e.Graphics.CompositingQuality = CompositingQuality.HighSpeed;
    e.Graphics.InterpolationMode = InterpolationMode.NearestNeighbor;
    e.Graphics.SmoothingMode = SmoothingMode.None;
    e.Graphics.PixelOffsetMode = PixelOffsetMode.Half;
    e.Graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAliasGridFit;
    e.Graphics.CompositingMode = CompositingMode.SourceCopy;
    base OnPaint(sender, e)
}

Some of these parameters have a huge impact on the rendering speed (and to the quality of the result).

The parameters used in the code example are already quite fast but maybe you find better combinations for your requirements.
