Well, it is surprisingly not that bad. I mostly fly GA so in the plane department I have ever only had issues with one plane but they supplied a 2K texture package as an option instead of 4K which solved all the issues. I can always run with texture quality on high so my sim still looks rather nice. I am on a windows pc that I built 3-4 years ago but I get 35 fps in payware and 50 in default but anything above 30 I can fly in. I just couldn't help but notice that most of the textures included in the scenery were 4K which is quite heavy for me. Not a big deal if you can't make a 2K texture pack, I can always do that myself but I just don't want to turn my texture quality down because it ruins the beautiful ground textures included in this scenery.
