Yes. I have an ATI Radeon X1600 with 128MB of VRAM. The shaders seem
to work (I get nice water effects, for example), the clouds look okay,
and I get no error messages on the console. It is *slow* though, with
the speed depending on the view, and how close I am to the ground.
Sitting at the default starting location at KSFO, I get:
Normal inside view:
17 fps - shaders and 3D clouds
20 fps - shaders
20 fps - 3D clouds
22 fps - no shaders or 3D clouds
External chase view:
3 fps - shaders and 3D clouds
4 fps - shaders
4 fps - 3D clouds
4 fps - no shaders or 3D clouds
Inside view, if I zoom in close enough so that I can't see out the
windows (and yes, it really does run a bit faster with shaders and 3D
clouds turned on, but the difference probably isn't meaningful):
40 fps - shaders and 3D clouds
38 fps - shaders
38 fps - 3D clouds
38 fps - no shaders or 3D clouds
In summary:
(a) Things work
(b) Shaders and 3D clouds slow things down, but not by much
(c) The view makes a big difference
(d) Being close to the ground makes a difference (although I haven't
tried to measure it)
