After a considerable amount of time spent experimenting and attempting at tweaks, I've finally decided that the costs of the "dynamic lighting" feature of Prepar3dv4, in terms of performance, far outweigh its benefits. How many times have you experienced studders and low frame rates during your most critical phases of flight, i.e attempting that blissful flare prior to touchdown? Well, it felt amazing to uncheck "dynamic lighting" in my graphics settings and get that smoothness back, without even having to wait for my sim to reload :) Please tell me about your experience, are you running it or not? Is there any hope for "dynamic lighting" at the end of the dark tunnel? :) 

With moderate settings at KSFO at night using Flightbeam's SFO v2, I am seeing locked 30 fps with no stutters and it being perfectly smooth. It seems to depend system to system.

Enjoy your dark and bleak unrealistic night flying!

What a sarcastic comment! Although the "Dynamic Lighting" feature is an attempt at realism, it does NOT disable lighting. I would advise you to do some research before posting up a response in this forum, Mitch. 

You and everyone else. Seriously, people are posting this stuff as if they are the first ones to take notice.....

Good points, Milton; it really does vary system to system. Anyways, since my first post, I realized that it was actually a high SSAA setting that was the culprit of my low fps, especially with the landing and taxi lights on full blast. I went from 4xSSAA to 2xMSAA and noticed a considerable improvement in FPS and smoothness. In terms of locking in my FPS, I've noticed better performance on unlimited and kept it as such, would you recommend otherwise?

What a silly comment! Dynamic lighting isn't all that!

After seeing that DL was limited from the start and then the performance penalty, I just left it unchecked from day 1. I am fine with the old lighting system where I can achieve a smooth flight.

Why is it so important to get in the last word...quick, someone post after me!

You gotta get in before the lock!

LOL.  Simmers are a funny lot.  You all make car forums look polite

 sweet, what a debacle

You are probably using display settings that are too high and running your system at 4k.

Now what hardware do you have? If anybody wants to use DL under 4k with SSAA enabled it just has unrealistic expectations.

This has been explained here in the forums before several times.

For DL to work under 4k you need to forget about SSAA and be sure you have a monster of a video card, 1080ti is highly recommended.

If it wasn't for Vic and the occasional use of his big gun (the lock) these forums would look like a nasty scene from GTA V

well, it does for e.g. PMDG. So not fully sarcastic, just a bit short mouthed ;).

But yeah, I'm also still doubting, but for now.. I just love the dynamic lights on Ai and online flying.. somehow
