Runway and a/c landing lighting (new drivers for GeForc

I've commenced the excellent RIVA tuner routine discussed here a week or so ago. I must admit that I have not yet completed the tune-up, but have successfully loaded the 29.42 drivers after running Driver Cleaner to ensure that all remnants of older drivers are gone.What I now note, besides what appears to be a better fps performance, is that the really nice yellow/gold lighting for runway and external views of a/c landing lights has gone, and now it's back to just plain "white" lights. The ones I had before this were from FSW, and dated back to just after FS2002 was released. This was a replacement file in FS2002Texture, as I recall.Has anyone else seen this issue? Could it be a function of the 29.42 drivers, or is there another setting that I have yet to tweak?Thanks.WinXP/SP1GeForce 3 Ti200Bruce.
