Smoke, yes I suppose it is a mod, not released though. Another one of my on going tweaks to make it look as best as I can. Believe it or not my smoke is set to low and still looks amazing. It's taken weeks to get it like this. No fps drop at all. V1.1 of the game is addressing the smoke lag issue. If mine still works after 1.1 I'll release it.
Thank you very much, means a lot. It's been around a while, it's been used by others, tweaked, copied, stolen (well not really stolen, I'm happy to share) I've tried others myself but I couldn't find exactly what I wanted, so I had to do it myself. It started life as a Kunos photographic filter I think from an early version of AC and went from there. The key thing was to keep it simple and easy to use and look good across all times and weathers.
