Yes, someone else mentioned in a WU9 topic that suddenly the ground textures in South Africa were better, and I noticed an improvement in the middle of the Nevada trip.
About a month ago, there was a topic “what do you think the june surprise is going to be”. Microsoft gave Blackshark.ai a huge amount of funding after MSFS went live, and there are several other companies who also have given them grants. I made the guess “I wonder if it is going to be BlackShark.ai is going to introduce new textures or autogen” but people generally shot me down on that guess. But seeing some of the improvements in the new WU, as well as some off the beaten track places, I am now generally wondering if the surprise is they are going to overhaul all the base scenery with new Blackshark.ai techniques. You need look no further than main Italy compared to Malta (which people have shown had no change in the base textures) to see the radical change.
