Ashley the difference comes in how many pixels are actually rendered by the GPU. I want the ability to compromise number of pixels (resolution) for game speed.
For instance, I was trying the game out on a 1080p laptop with integrated graphics and the game ran slowly because apparently the graphics card simply couldn't push that many pixels. In such cases, the player should be able to select a lower resolution, keeping the fullscreen experience but with a slightly lower image quality.
'Letterbox scale mode' I guess would be called 'auto' resolution because it adjusts to the resolution of the screen.
appchogie haha, no worries mate. We're all learning and we can all learn things from each other ;)
However yes, you may have missed that my problem is GPU capability, not screen geometry.
