- Minimum - sets the display quality to low, disables stage weather, effects (global, hit, and knockback smoke), screen flash, ambient lighting, the HUD fade, shadows, stage effects, and the menu's background/animations
- Low - all things from minimum are still disabled, except the menu BG is enabled
- Medium - all things from low, except global effects, hit effects, knockback smoke, HUD fade, and shadows are enabled, with the stage effects being set to simple
- High - display quality is set to medium, stage weather and ambient lighting are enabled; the rest is unchanged from medium
- Maximum - makes the game's performance very smooth (depending on your computer settings), acting like the normal game; all things are at max (display quality is set to best and stage effects are completely enabled)
The fullscreen quality can also being adjusted to hardware (which will enlarge the game's window as if it was still in normal size resulting in blured graphics) or software (which will optimize the graphics without any detriment keeping the smooth edges) quality.
Being a Flash-based game, changing the quality will determine how fast Super Smash Flash 2 frame rate will run. Setting the quality to low could result in the frame rate running faster at the cost of good visuals, while setting the quality to high does the opposite, the frame rate could be slower by keeping good visuals. The same happens for fullscreen quality, setting to hardware quality will make the game run faster while software quality will reduce it.
