Quality

Quality is a section accessed from the options menu, present in Super Smash Flash 2, that allows the player to adjust the game's visuals. As of Beta, it can be set to seven quality levels:
 * Minimum - sets the display quality to low and disables stage weather, effects (global, hit, and knockback smoke), screen flash, ambient lighting, HUD fade, shadows, stage effects, and the menu's background.
 * Low - all settings from Minimum remain, except the menu BG is enabled.
 * Medium - all settings from Low remain, except the global effects, hit effects, knockback smoke, HUD fade, and shadows are enabled; stage effects are also set to simple.
 * High - display quality is set to medium, stage weather and ambient lighting are enabled; the rest is unchanged from Medium.
 * Maximum - all visuals are enabled and the display quality is set to best.
 * Custom - players can customize what visuals they do or do not want and what setting they want for fullscreen.

The Fullscreen Quality can also be adjusted to one of two different options. The first option is "Hardware (Speed)", which will enlarge the game's window as if it was still in normal size (640x360), resulting in blurred graphics. The second option is a more crisp "Software (Quality)", which will optimize the graphics without any detriments to keeping the smooth edges, resulting in a native and clean look but slower speeds.

Fullscreen Quality is automatically set to hardware for minimum, low, medium, and high quality levels, while it is set to software for maximum. However, it can be changed to either one when the player sets the quality level to custom.

Being a Flash-based game, changing the quality will determine how fast the frame rate in Super Smash Flash 2 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 same happens for fullscreen quality, as setting it to hardware quality will make the game run faster while software quality will reduce it.

It is similar to the screen display and deflicker options from Super Smash Bros. Melee and Super Smash Bros. Brawl, respectively. However, these options do not affect the frame rate of the games.
