I haven't turned anything off, ever. I was playing earlier no problems, reconnected after I had to step away, came back and all hats were gone. Then in the same play session body parts went missing. Bloop has the same problem. I thought, maybe it's my GPU, maybe we both have the same GPU and need a driver update. Nope, not the case. Idk what it is but I'm not inclined to care right now. It's TF2, shit happens. I thought maybe it was the plugin, but if that is working fine for everyone else than it probably is just TF2 being TF2.You turned that off yourself. It is in the menu.
I thought that would only hide the hat effects, wich make it harder to get headshots. Oh well ty for clearing that up.
