Selects an amount to scale the primary buffer by. May cause slowdowns in certain applications or on certain computers.
Can enhance the resolution of 3D applications.

The following options are available:

1x scale

Disables primary buffer scaling.

Scale to screen

Scales the primary buffer to the current screen resolution.  May cause significant artifacts.

Maximum integer scaling

Scales the primary buffer to an automatic amount, by a whole number amount.  This may reduce artifacts compared to Scale to screen.

1.5x scale
2x scale
2.5x scale
3x scale
4x scale
5x SCALE
6X scale
7X scale
8x scale

Scales the primary buffer by the specified amount.  Note that this may fail if the selected mode scales the primary beyond your graphics card’s capability.

Custom scale

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 1×1, disabling scaling.
