1.2 Basic Settings

The Main screen - Basic Settings section let you set following options:

Low Priority - By default application priority is set to normal. If you have weak CPU, you can try setting priority to low to keep your PC performance.
Auto Hide HUD - HUD is hidden when the game window is not active.
Auto Terminate - When the game process terminated, HUD process will auto terminate.
High Framerate - A higher framerate means higher graphics resource consumption, but it will make your HUD look smoother. If this option is checked, HUD will work at about 60 frames per second. If it is unchecked, refresh rate will be about 30 fames/sec.
Paragon capture - When you leveling your paragon and this option selected, HUD will automatically take a screen shot for you. It is recommended to keep this option disabled.
When this option is enabled, it will save a lot of screen shots to your hard drive.
Text to speech volume- set speech volume. There is TTS built-in component in TH LightningMOD. Some plug-ins use voice to remind you about actions to be taken or to inform you about important events.
 in Language - You can set your preferred language from drop down menu. Be aware, some plug-ins support only traditional Chinese and simplified Chinese and language can't be changed.

DirectX menu - you can select DirectX version from drop down menu. It can be used in case of performance issue.
Don't touch this, if you are not sure.
