Hi! First, big thanks for 2.6, especially the new "Instant Replay"-function is amazing!
Two things catched my eye, but i´m not sure if these appear on your machines, too (i´ve an ATI-Card):
Firstly: The Scenery farer away becomes blurred:
Secondly: This is very mysterious; When it´s night, I can´t see any lights (neither the instruments in the cockpit, nor the runway lights), but when i change the view, then sometimes the lights appear. Because i´m using an ATI card, i had to turn off the "Use Point sprites for runway lights"-option in the "Rendering options" window, to see the runway-lighting (in FG 2.4 also). If i switch it on, i can´t see the runway-lighting, but in exchange the cockpit and other lights are visible normally. But it becomes more mysterious This seems just to happen between the following clocktimes seen on the screens:
Before 23:00, everything works fine:
After 23:00, just the stars are visible, no other lights:
The same ~5'30 hours later:
Around 5:00, everything works fine again:
In 2.4 everything works normally despite of switched-off point-sprites.
My OS is Windows 7.
I hope this helps to find the cause Cheers,
