This command will toggle (enable and disable) End-of-Frame ImageSpace graphics settings including blur and contrast adjustment. These graphics settings can cause lower frame rates, because of this, this command usually raises FPS. The changes made the graphics settings are not saved - you will need to re-execute this command when you close and re-open the game.
If end of frame imagespace effects are enabled, this command will disable them. Otherwise, this command will enable them.
The above command is the same as the first (TEOFIS), it is simply a longer version (alias).
