Is he notified at all? He might not be aware of the issue or something.
If he is, I'd love to hear some input from him about what he thinks is causing problems, someone might be able to help.
This mod makes me sad for being broken, it's THE most useful mod in game imho. I consider it a thing that should be implemented in game by default, not only as part of mod pack. Smoke is nearly impossible to see from within, no matter what I do with the settings.
edit: sadly, GUI refresh rate doesn't help me one bit, hangs every time I exit the match.
