There are several posts about this but they are somewhat old.
Above all I want to ask this question with a view to the future, to what will come in Infinite flight. I do not want to be short of the power of my device because for my Inifinte flihgt it is already my main simulator ahead of Xplane 11 that I got tired and I desperate.
The issue is that I have been told by twiter that they are working on putting clouds (I put a photo to see that it is true), I have read that now they will try to put terrain above latitudes of + 60º and then they will add autogen (what more will demand).
Now I have a OnePlus 3T with 6GB of ram, it gives me about 170.000 in antutu and I can play to the top of graphics in Infinite flight in online although it is lagged in very recharged airports, I will buy the OnePlus 7 or the 7T with 8 or 12 gb of Ram, which will be according to the forecasts in Antutu about 375,000-390,000 points.
Maybe I value the xiaomi black shark 2 with 12 gb ram that has liquid refirgeration and reaches more than 380,000 points in antutu.
With that would be enough?
