On the right top corner of the screen I have it turned off but how do you turn on the Iray render preview box (or whatever its called) please.

In your viewport, there should be icons in the upper right. These allow you to customize the View.
The round thingy to the left of the View selector box? (Mine is set to Texture Shaded.)
Nvidia Iray view is under there.
Thx but you misunderstood I meant the small Iray RENDER preview box on the top right box (not in viewport area)
If you hover over it with the mouse you should see the same controls as in the Viewport, just use these instead.
