<p>
  Selects an amount to scale the primary buffer by. May cause slowdowns in certain applications or on certain computers.<br />
  Can enhance the resolution of 3D applications.
</p>
<p>The following options are available:</p>
<h3>1x scale</h3>
<p>Disables primary buffer scaling.</p>
<h3>Scale to screen</h3>
<p>Scales the primary buffer to the current screen resolution.  May cause significant artifacts.</p>
<h3>Maximum integer scaling</h3>
<p>Scales the primary buffer to an automatic amount, by a whole number amount.  This may reduce artifacts compared to Scale to screen.</p>
<h3>
  1.5x scale<br />
  2x scale<br />
  2.5x scale<br />
  3x scale<br />
  4x scale<br />
  5x SCALE<br />
  6X scale<br />
  7X scale<br />
  8x scale
</h3>
<p>Scales the primary buffer by the specified amount.  Note that this may fail if the selected mode scales the primary beyond your graphics card&#8217;s capability.</p>
<h3>Custom scale</h3>
<p>Scales the primary buffer by a custom amount.  This amount can be entered in X and Y dimensions and may be an integer or floating point using the boxes provided.  The default scaling is 1&#215;1, disabling scaling.</p>
