• Custom OpenGL settings displays a list of the custom settings (or "tweaks")
you have saved. Selecting an item from the list will activate the setting. To
apply the setting, click OK or Apply.
• Save As . . lets you save the current settings as a custom "tweak". Saved
settings will then be added to the adjacent list. Once you have found the
