The NDU “fix” should be fairly benign. It’s easy to reverse anyway. I cannot certify whether it works or not, as I haven’t done flights more than 8 hrs. And long-haul is 8+ hrs. Obviously. 

Use the start button to search for "Regedit". Navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ndu. Find and right-click the "start" option and click on "Modify". Change the value from 2 to 4. Click ok and reboot the system.

I think its a placebo. I have applied this "fix" and nothing changed.

It could very well be. Difficult to know if tweaks like these actually work.

5 hours is fine, but 7 to 8+ you will experience performance loss regardless. It also depends on what area in the world you fly in. For example - I can fly from Cork to Tenerife and back to Cork which is a 9 hour round trip when you factor in ground time. With that flight I don't experience any performance loss whatsoever, but when I fly Manchester to Hurgahada and back which is around a 12 hour round trip my performance drops by over 50% halfway through the return flight, and those flights are in the Fenix 320.

So these aren't single long haul flights, but turn-arounds without reloading the sim in between?

If the latter, I can see how this could possibly lead to decreased performance. There's a chance the previous flight plan or something to do with the previous leg isn't unloading fully and then the system is getting bogged down as another flight plan is loaded perhaps.

Always a good idea to reload the sim between flights IMO. Not realistic I know but you can just re-spawn on the same stand with the same panel state in a few extra minutes.

I managed a 6 hour flight (single flight, not a turnaround) in the 737 today and had no degradation that I could tell.

SU 10 Beta,

DX11, PC crashed after about 4Hrs of flying Fenix 320 (it could be hardware related issue).

DX12 + same settings, several flights over five Hrs each, so far with no FPS degradation, no CTD and no PC crash.

 

fingers crossed that we are getting there.

CX11 here, no Beta.

Flew the Fenix on what was planned to be a 5Hrs flight today, and performance also dropped roughly after the 4HRs - from smooth flying to terrible slideshow. 

Rage-quitted, and took the dogs for a long walk on the beach. The lab loved it while I suspect the short-legged one had mixed feelings about it 🐶

Cheers,

I don't have time to make such long flights, but for you who do and like to delve into computer "nerdship" occasionaly, I ran across this link - ISLC 

He is the creator of DDU.

Just noticed this program has already been mentioned.
