Maybe this is intentional design, but when selecting:
- the smallest resolution (640 x 480)
- the highest Graphics Quality (Fantastic) in Player Configuration

and then running the Windows Player in fullscreen mode, the cubes in the scene look very aliased and it also looks like they sink into the floor.

To reproduce:
- Open attached project and launch "LightShaft Spot"
- Build And Run a Windows Player and observe the scene

For comparison, build and run the same scene in fullscreen enabling:
- the highest resolution (1920 x 1080)
- the highest Graphics Quality (Fantastic) in Player Configuration
