alright so heres what you do... its real simple.go to your nexon folder which is in your C drive, then click on combat arms. go until you see someting called profiles. double click that. then double click players. scroll down until you see somethin called light map. change that to 0 instead of 1 (if you want gore also type in 1 if you have it on 0) that should do most of it!
EDIT!!!: also if you take all of the details out such as FX detail, Environmental detail, and Extra Detail all the way at the bottom that helps alot too :P your welcome :P :P :P
