Yeah, interesting to discover.  For me, it looks like turning off all shadows and decreasing or turning off dynamic reflections altogether seemed to do the trick.  Now I can sit at the "heaviest" airports with the sliders to the right and manage.  I didn't know that dynamic lighting produces shadows and reflections as well.  Interesting little feature in this new verison;-)

Today I installed envtex beta and configured it accordingly. 

When I start up the 777 at night my landing and runway don't light up the run way like they used to.  I have dynamic lighting enabled as well as HDR.  I have the latest Nvidia drivers installed.  I don't think that it was envtex that caused this but I really don't know what could be the cause.

This was the item that changed between it working properly and not working properly. What would lead you to believe that this is not the cause?

I'm not ruling it out but a  friend of mine did the same thing (installed envtex) and his lights are still working.  I will reinstall the 777 and see.

Don't reinstall the 777 unless instructed to do so

I reinstalled this morning and the landing/runway lights are once again working.  During the reinstall, the Ops center complained about some missing textures.  In any case, I am now able to fly and enjoy night time flying.
