It shouldn't auto detect it because its not installed. You will have to find it yourself. But, I rarely ever had Xfire up when I played LFS because when someone talks to me my xfire minimizes and my gas would go full throttle and I would crash.
It does get frustraiting once in awhile because you have to start off with a single shot and everyone else pretty much has full auto..So the weapon I suggest you using is the shotgun it sprays about 5-6 paintballs every shot but you have to be quick because its a slow gun.
Oh and if you dont have the mod already, I suggest not downloading it ingame because its a big mod and will take you awhile to download..So get it from CoD files its Modern Paintball mod.
Yeah I know, I have always used the wheel view. It's hard for me to get used to not seeing the brake disc there anymore. I guess taking anything away from the car to get more FPS for people is good.
