Dynamic lighting

Is there any way to get landing/taxi lights to show with dynamic lighting off?  P3d 4.2 didn't seem to fix anything. Lot of people are reporting a big performance hit.  I'm locked at 30fps without it and it's smooth, turn it on it's a slideshow.

It seems to be system specific.  I have an older system and it dynamic lighting doesn't cause performance problems.

Yeah, but that really doesn't help my situation. An option to use legacy lighting would be great.

Turn the volumetric lights OFF.

Still getting big performance hit with volumetric lights off and dynamic lighting on. It's not just the 757, but other developers who use it in their models. Can't figure out what's causing it. Using msaa doesn't help like other people said on p3d forums and neither does panning around the aircraft. With dynamic lighting off I get 30fps locked and it's smooth.

With the new Prepar3D v4.2 update, Dynamic lighting performance has improved. Maybe the 757 needs recompiling in the v4.2 SDK.
