Hi Thorsten, Just to say that if you have a serious cloud coverage (with or whithout rembrandt) you'll never get more than 30 fps and more likely 15 fps. Here, core i7-3Ghz-16 MB RAM, GTX 680-2MB VRAM, 1920*1200px, you can set a 200 km visibility, every shader to the max, complex models like the f-14b + the Vinson, and fly around SFO with a steady clamped 50 Hz. But as soon as the clouds start to cover the place the fps drop to 20 or less. So I never fly with the cloud slider set to the max. CPU/GPU power doesn't do much in regard to clouds rendering. Since I got this new powerfull box, everything got *really* improved but clouds rendering. Advanced weather cloud coverage seams to be a bit faster than the visually equivalent global weather cloud coverage (just talking about what you see from the cockpit when inside the weather, that is plenty of grey everywhere). Isn't that you are seeing ? Alexis > > > It doesn't seem to be Flightgear though...
