I can honestly say that on V4.3 and the latest update to the NGX, I am encountering this freeze/lock up problem every time I take off. I always start in P3D  at a gate with engines running. I shut down the engines after the "setup countdown" so as to do my Virt. Airline / GSX stuff. I can taxi fine, but come take off and raising gear, the sim stutters a few times - like way too many textures trying to load in - then freezes. I can do the gear thing and have tried the clicking on the screen(s), but no luck getting back into the flight.

My system is i7 8700k, 32gb RAM with an EVGA GTX 1080i 11GB, 1TB SSD drive and a 4TB HDD.; Logitech (Saitek) Flight Yoke System, extraa throttle quad; Thrustmaster T Flight Rudders.This is a new computer, only a week old. I use nearly all ORBX products, from the airports to the most all LC, Regional and Global scenery textures, FTX Vector. Latest FlyTampa All are up to date - spent nearly a week reloading it all 😀. I do not use the HDR or the dynamic lighting at this time. At first I was and the problem began right after the update, so I turned off HDR and Dyn Ltg to see if t hat was it. 

Don't know if the above will help. Have searched through the Forums for possible fix, but only found a similar topic from Aug 2016. Right now it appears only recourse seems to be uninstalling and re-installing the 737 and not do the update. 

Kind regards,

Try it without the virtual airline "stuff."

The reason why you haven't found similar topics is because this is not a known problem with the NGX.  Try looking at other items such as FSUIPC.

Okay Dan. Explain this then, please. I deleted the patched Base pkg, rebooted, then reloaded the original Base pkg sans the latest patch - and everything works fine. This would include using FSUIPC for axis/button/switches control and Dyn Lgts. Now, I load PMDG patch for the base pkg with nothing else being changed, the gear up problem reappears. Without FSUIPC, gear up problem. I did not load in the Logitech drivers for the Flight Yoke system - just the Thrustmaster T-rudder driver. Am using whatever MS dwlds per quite a few "suggestions" between Forums and U-tubers for the Yoke system.  Know this is a different sim system, but FSX:SE version with patch runs fine with the latest patch. Soooo... scratching head on this. I just uninstalled Base pkg, rebooted and reloaded again the Original dwnld Base pkg - and hey hey - all works again. So I will make the conclusion that v4.3 broke something that PMDG was trying to fix with their latest patch hence the issue I am having.

Kind regards,

That conclusion is only valid in isolation; however, there are thousands or more of NGX users and you are the only one reporting this problem.  It sure points to something unique in your configuration.  I think the best course of action for you is to explain this problem in detail, perhaps reference this thread, on a support ticket at PMDG Product Support.  I expect you will find more in depth support directly from PMDG than from a user forum in this case.

Thank you, Dan. Did find a topic from 2016 on this same issue dealing with P3D.but again - no answers hence restarting the thread.

Kind regards,
