Nope.......nothing is changed except the renderer.
Of note - if I run render diagnostics, this is what I get:

MENTAL RAY RENDER DIAGNOSTICS:
Textures
- Filter type of file node "file1" (Quadratic) is not supported.
- Filter type of file node "file2" (Quadratic) is not supported.
// Warning: 2 warnings, see script editor for details. //

File 1 & 2 are the wallpaper bitmaps for the 2 walls.
