Hello , I will be showing you guys some commands that helped me increase performance in the game, before these, I couldn't play in my native resolution (1600x900) because lag was terrible, but after these tweaks, I have no problems at all and I can play with my original resolution, they are just some simple commands that need to be typed into the chatbox, lets get started...

Click the Chatbox in-game and type the following..

/option SpellEffect_DisplayLevel 4
This setting is used to decrease the particle level in the area
You can set this from 0 to 4 ,
0 =Shows All particles.
1= Shows only particles in your raid.
2= Shows only particles in your group.
3= Shows only your particles.
4= NO particles.

/option RenderSetting_EnableGrass false
I think this one speaks for itself, removes all the grass leaves in the level, the changes are barely noticeable.

/option RenderSettings_RemoveFoliageAroundCharacter true
Not sure what this does, something to do with tree leaves or trees in general, but it boosts up some performance, again, the changes are barely noticeable.

/option RenderSetting_HighQualityNPCRange 0
This option affects your character as well as other characters, the number changes the meters of which you can see hi-res and detailed characters, setting it to 0 will show no high quality in characters, but your character's weapon will be affected too and it will show all black, I recommend setting this to around 10 or 15 but if you want max performance, set it to 0.

/option RenderSetting_ViewDistance 25
Reduces the view distance of the game , you won't be able to see too far, but it will increase your performance.

/option RenderSetting_AnimationLODRange 0
Not sure what this does, but it doesn't hurt to toggle it.

Here's the list of the original values for each one :

/option SpellEffect_DisplayLevel 0
/option RenderSetting_EnableGrass true
/option RenderSettings_RemoveFoliageAroundCharacter false
/option RenderSetting_HighQualityNPCRange 30
/option RenderSetting_ViewDistance 0
/option RenderSetting_AnimationLODRange 60

-Some bugs can occur related to the /option SpellEffect_DisplayLevel command, such as invisible walls, invisble stuff that kills you, etcetera, it is very rare but it can occur,(I've only seen a problem with some lasers in a certain part of the game) if you happen to be stuck somewhere, not being able to advance properly, revert this setting's value to 0.
