Through my ATI 9800 XT, the ILS glide slope markers (for example "yellow brick road") show erratically or not at all until the last mile or so from the runway. An nVidia 5600 on the same system shows them steadily for several miles out. Anyone else have this problem? Anyone have a solution? Thanks.

Try a different video driver. After upgrading to the ATI 4.12's the VC panel in the Aeroworx B200 became translucent on my system. Was never a problem with previous driver sets.The ATI 4.10's and their Omega counterparts (2.5.76's) worked very well for me in this sim. But each system works differently with each driver set. Experiment until you find a set you're happy with.Cheers,Greg
