Hi all,
I had some issues with FPS lag in my game, tbh I have quite a decent setup, and I could not understand why so I Googled for answers everywhere. I spent hours trying different options and settings until I had found exactly what helped me the most and thought I would share it with all of you. 
This guide isn’t there to show you how to change the basics like shadows, draw distance, etc… Those you can play with for yourself to get the best possible results with visual imaging to suit your eye. The only change you need to make in game for this guide is set the Lighting Enrichment to 1
This guide is a brief one on some “behind the scenes” changes you can make to improve responsiveness of the game in general in addition to the visual changes mentioned above.
If you are looking for a guide on changes for visuals in game there are many on the forums and on the net that explain each and every setting (although they are pretty self explanatory tbh).
So where we start is with a few necessary changes to the S1Engine.ini file:
Note: If you want to know what any of these changes do please go take a look at this site (just so you don’t change anything that will give you undesirable results) - LINK
Firstly you will need to look for “bSmoothFrameRate=true” here there are 2 major changes you can make (this generally helps for people who have higher end CPUs).
1. Change “bSmoothFrameRate=true” to “bSmoothFrameRate=false” (This is what I currently use)
2. Leave “bSmoothFrameRate=true” and increase the min/max values below to a desirable setting (30MIN/130MAX is a good place to start)
Make the following changes to other values
DisableATITextureFilterOptimizationChecks=True > DisableATITextureFilterOptimizationChecks=False
DynamicShadows=True > DynamicShadows=False
LightEnvironmentShadows=True > LightEnvironmentShadows=False
MotionBlur=True > MotionBlur=False
DepthOfField=True > DepthOfField=False
Bloom=True > Bloom=False
UseHighQualityBloom=True > UseHighQualityBloom=False
bAllowBetterModulatedShadows=True > bAllowBetterModulatedShadows=False
bEnableForegroundSelfShadowing=True > bEnableForegroundSelfShadowing=False
MaxShadowResolution=2048 > MaxShadowResolution=512
Once you have made these changes to your config file we will need to open your graphics card driver window and set app specific settings for Tera.exe:
1. Under the anti-aliasing option set this to override application settings and set the level to either x2 or x4
2. Look for quality settings and set this to performance
We are almost done now, for users with multicore processors (which I assume everyone is if you play this CPU intensive game) you will need to do the following:
1. Download this app: LINK
2. Click check status
3. If you see any cores labelled “parked” click the “unpark all cores” option
Once you have done the above go back to your S1Engine.ini file and search for the line “CompatLevelGPU”, once you have found this add the following line directly below “CPUNumLogicalProcessors=X” (Where “X” is the number of logical processors windows detects for your CPU, the amount of logical processors can be checked in the performance tab in your task manager where you will see the amount of processors windows detects there)
And there we go you should be getting quite a decent FPS jump with those changes.
