I'm not really sure what's wrong with my Killing Floor, but whenever I play it on my friend's computer it works perfectly. But when I play it on my computer, all the characters, specimens, flamethrower flame (the one coming out the flammable gas exhaust port/blower.), ejected shells, and guns are white. Also the red dot sights and holographic sights aren't transparent. There's only 2 characters that aren't white. That's the Private_Schneider (I think his name is) and the face of Corporal_Lewis (Once again, I think his name is that, he's in a woodland Army Camo). I'm not sure if it's a glitch or my computer doesn't have a graphics card. Or maybe it's just too old for the textures/meshes and Steam/Killing Floor doesn't install/show them. I have some screenshots of what I'm experiencing below.
