Taxiway lights at O'Hare do not render properly for any of us who use FSX in "Preview DirectX 10" mode.
That to be expected. We don't support DX10 in any of our sceneries, with the exception of JFK which, incidentally, took a lot of criticism for having less ground texture quality compared to the other ones.
I'm one of the many FSX users who run aircraft liveries and airports only in Preview DirectX 10 mode. If a livery or airport does not render properly in Preview DirectX 10 mode, I don't use it.
That's your own choice, but you are in a very small minority. DX10 Preview is so buggy, that not even the default airports renders correctly. Is really an unfinished work.
The problem at O'Hare does not result from a missing or corrupt fx_2.bmp file. It would be a shame to leave the problem uncorrected. Other than the problem with the lights, the airport is an impressive work. I hope a patch will be issued.
There's no "patch" planned because, the DX10 problem lies in the very way how the airport is done which, due to the vast majority of users, that are using DX9 ( or even FS9, btw ), DX10 compatibility is not rated very importantly, which is clearly shown by the sales. Having full DX10 compatibility would mean redoing the airport from scratch, and making a specific FSX-only version, losing FS9 back-portability in the meantime.
You want a fully native FSX DX10 compliant airport: we have Cloud9 Orlando.
Wasn't for the "small" detail that, due to the constraints of having full DX10 compatibility, we had to renounce having a certain kind of ground rendering ( and of course it's FSX only ), resulting in actual sales about 1/10th of O'Hare just because of this, it's clear that users are voting with their wallets and, the vast majority of them is not prepared to lose the ground quality they get used to, in order to gain DX10 compatibility, which can only means, DX10 users are a very small minority, otherwise we would have seen a surge in KMCO sales, because it's the only scenery that is 100% FSX native.
We are exploring new solutions for KDFW to finally have DX10 compatibility, with a very high quality custom ground. This means the FSX version will look much better than than FS9. Which is something we might afford now, year 2010, when FSX is a little bit more established compared to 2 years ago, when O'Hare was released. If we released an FSX-only or even an too muchb FSX-oriented O'Hare in 2008, we would have gone bankrupt already by now...
Which doesn't change the fact that, the scenery is done like is done, because these are things you need to decide at the initial stages of developement, it can't be just "patched", because it would mean basically redoing it. In fact, what we are doing for KDFW, doesn't have anything in common with all our previous products, the whole design process is radically different, and it's not something that can be retrofitted to an already existing scenery.
