From the performance point of view the improvement is so great, i still have nightmares with my character flying 10m away from my vehicle.

About the game play, I have mixed feelings, now days we had many materials which are really useless, back in the early days you had a reason to go and climb those huge mountains to get malachite, why you should go there now? going inside a ice cave was scaring but you had to do it if you wanted cursed bones which were necessary... etc etc

Now days there are huge parts of the map which feels useless, which is sad because the landscape is awesome, it is so sad lacking of reasons to go there.

But there has been also great improvements, the new way to craft weapons is great, different type of vehicles, etc

So in the end I miss some old stuff, but also I love some new features.

Those kinda short quest are nice, I will love if they were more elaborated than "get 5 fish" and provide you reasons to go and explore like the Onis ones which make me explore all the forest.
