I've read the whole your post, MeusH and it makes a lot of sense, however I didn't know each puff takes up a vehicle's slot.MeusH wrote:....This is why I think "more smoke" patch has less chanches to be merged, because each smoke puff uses vehicle slot. But "smooth economy" doesn't drain more memory, and it is configurable, so expect this in a merge-me list.

Although I think Bjarni was mentioning it some time ago...interesting thing is, that Integrated games (internet games too) with quite many trains were working flawlessly without any hiccups... I guess it would be only for computers with more RAM?
The good thing is, diesel_smoke patch is also configurable - setting 2 can decrease smoke quite a lot - to the amount OpenTTD has now, or a bit more...
