Happens to me as well. I'll also get very laggy hit boxes, like I'll be all the way around a corner away from someone I was fighting and suddenly I'm dead, even though I am FAR out of their range of sight. I get the random floating muzzle flashes, floating guns, etc. Dead bodies appearing and disappearing. Sometimes I see CT as T and vice versa. Sometimes I get models that are doing that "Jesus" pose (best way I know to describe it) and floating around.

From what I've been told, the gore/blood mod fucks with the reg. I don't know that to be a fact, it's just what I've heard.
