Occasionally, when Rico and sometimes some enemies get shot, strange red lines and objects start coming out of the people. Sometimes bullet holes can be seen on these red lines. This sometimes happens with vehicles as well; sometimes strange bullet holes can be seen surround the car but not actually on the car itself. When this happens the frame rate drops down to about 15 fps. I'm running everything on max settings on a GTX 670 and have stress tested the card numerous times to see if its the card that's causing it and everything seems to be fine. I've also stress tested my cpu (i5-3570k) but everythings fine there as well. Anyone had anything like this? If I can get any screenshots I'll post.
