KDFW is already DX10 compatible, 100% FSX native code and P3D compatible, and very good with fps.
The KLAS and KORD overhaul are way more pressing, yet users on the recent poll we had didn't seem so interested in KLAS upgrade, as an high priority. KDFW would probably be even less than that.
Which means, that fix might only come if we find some additional spare time, but right now we really have our hands full, with starting KMEM, finishing another large US airport we have been working at for a while, updating GSX with deicers and other new features and doing the GSX Cargo Expansion too.
