Please run the FSDT Live Update now. I'm confident it should work much better now.
Thanks very much for the fix Umberto, I was only having slow texture loading not blurriness but the latest update works great. I think it also reduced the CPU load if I compare it to GSX v1.
Yes, it's a bug we had since the first 64 version. But you needed jetways to notice it, because they are created everywhere, not just on an FSDT airport.
