Just bought & installed the excellent IMHO Black Marble for FSX:SE. I'd made a cargo flight from KSTL recently in the daytime, & seeing as my USA is devoid of photoreal scenery for the most part, where better to check out the new effects. NOTE this is the Base software which uses native sim data only. The Vector add on injects all the real world roads into the sim! Anyhow, for those of use who haven't bought Vector yet - here's the the native FSX. You can tweak loads of parameters for the lights - I can get the FPS into single figures by overdoing it!
