I am trying to make the the graphics look as best as possible. I have the first Splinter Cell game and would like to know some tweaks if possible. I do not know the parameters of the the config so I will post here:

[Engine.EPCGameOptions]
AnimatedGeometry=True
ShadowLevel=0
LightMapsLevel=0
TextureLevel=0
Resolution=1920x1080
AmbiantVolume=99
VoicesVolume=99
MusicVolume=99
AudioVirt=2
Sound3DAcc=True
EAX=False
InvertMouse=False
FireEquipGun=False
MouseSensitivity=29
ShadowResolution=2
EnableFadeOut=0
FadeOutNearPlane=1000
FadeOutFarPlane=1250
SFXVolume=99
Brightness=42
Gamma=48
EffectsQuality=3
FadeOut=0
VidMem=2
GraphicsCaps=2
EAX_Capable=False
AntiAliasing=4

How can I make it any better? How High can I put the parameters that are at 0 or is that the best? I have the game set on high with everything and was able to use custom resolution just fine however... how high does the AntiAliasing go? I put it at 4 for now. Please help.

Thank you.
