In my experience, when performance varies so much between different users, it’s often down to the VRAM. With my RTX 4090, I’ve got plenty of headroom, and the airport runs absolutely flawlessly for me, with no stuttering whatsoever. But when the VRAM is full, performance plummets. That hasn’t been the case for me so far, though.
There’s no question that the building and ground textures all look a bit sterile. So I agree with you that I wouldn’t go so far as to say the airport looks great. But for me, the update has optimised key aspects, so I’m satisfied overall. But of course, satisfaction ultimately depends on performance above all else.
This evening I’ll take a closer look at how well BATC is working.
