Okay, I don't really think that modifying the graphic settings using this method is a good idea, because I believe the GameOptions.ini is different on each operating system, and between 64 | 32 bit OS.
Your settings as you provided:
Code:
WIDTH=640
HEIGHT=480
DETAIL=3
MIPMAP=2
FOG=0
ENVIROMENT=0
SHADER=0
BLOODEFFECT=2
BULLETEFFECT=2
---
Mine is way different by default actually:
Code:
WIDTH=1024
HEIGHT=768
DETAIL=2
MIPMAP=0
FOG=0
ENVIROMENT=0
SHADER=0
GAMMA=0.500000
SKULL=1
BLOODEFFECT=1
BULLETEFFECT=1
USEHELP=1
KILLCAM=1
RIGHTRADER=0
PARTNER_RATE=0
I believe using the in-game settings to modify the graphics would be way better and non-risky to do rather than doing it manually!
Thanks for share anyway.
