On RWG in a17:Random worlds in a17 onward will be fully "pregenerated". This means that the world generator will output the same data structure as navezgane but in a save folder. This means that any rwg world will load just as fast as navezgane going forward.
After fixing the vehicles and adding new ones it was determined that RWG's runtime code was just waaaay too slow. So now it instead gets all the data set up and exports it in a common format which allows for quicker chunk loading.
With the change to pregeneration and using the socket(tile) system over the entire world there will be some other changes as well. For the better. Over the next couple of days I will give a bit more detail on what else these changes to RWG mean for the average player, modders, and server owners. I think most will be very happy.
More to come...
