Why did you do this: Higher resolution ground Textures ( from 1.36 m/pixel to 68 cm/pixel )
Because we didn't find a noticeable hit on fps, on a good video card with enough video memory, something that one has to have anyway, to use FSX.
If you put down the slider that sets Maximum texture size one notch, it would have exactly the same effect than using Zurich 1.0: it will use 512x512 textures instead of 1024x1024 textures.
This way, users with enough video memory can enjoy better resolution, and user with less video memory, can simply use the texture size slider, and have exactly the same result than Zurich 1.0, without having to release two separate versions of the scenery.
