This game looks great ! But sadly i have an ATI card :/
My card is an HD 5770 on win7 64, and i experience the most common problem with ATI cards : planet and ship icons disappearing a few second after game start, or never appearing at all.
I also have the same disappearing problem with the green direction lines, either thoses showing the current ship course, and i cant even see the destination height line even by holding CTRL.
Those problems might not be linked because lines disappear a few seconds after icons.
Without lines and icons, quite hard to play ^^
I tried a lot of ATI settings, even completely disabling AI by editing profiles.xml (tutorial here : http://www.moddb.com/mods/perfected-doom-3-version-500/features/how-to-disable-catalyst-ai-with-the-latest-ccc
) but nothing changed at all.
Finally I managed to find some kind of workaround by putting an older atioglxx.dll in star ruler folder, from old catalyst drivers (9.11).
It partially correct the problem, by replacing the missing icons with some random garbled texture, changing with each game session, and lines are present but barely visible (might be an antialiasing issue, i still have to make some tests).
here is a screenshot with planets on background and some cruisers on foreground :

if needed the catalyst 9.11 win7/vista 64bit dll i am using : atioglxx.dll - 2.5 Mb
with 9.10 and previous drivers the game will not be able to launch, and starting from 9.12 up to 11.6 the bugs are still there :/
Would it be possible to provide a command-line option for choosing opengl version, or maybe even other irrlicht versions if possible ?
If you could make a simple compatibility mode by trying to use different ways of rendering lines and icons that might do the trick !
I am open to anything to help you resolving this issue, and i am sure that a lot of people in the community would gladly make a donation to get you an ATI card ^^.
In the meantime i think i will try to buy a secondhand geforce card :/ ...
