Found a few possible graphics glitches, I'll screen shot and add them to this post as I find them (with location data overlay). See profile for system specs if needed:
(1). Co- planar Poly / Zplane (dunno). Map: Farm House
(2). Decals of bullet holes even though glass is broken out. This appears on several cars, all maps, and at random. Map: Farm House
(3). Bullet hole decals the same for Tires and Vehicle metal body parts. Map: Farm House
