Hello
First of all I would inform about my system setup:
Windows 7 Ultimate 64-bit
Intel Core i7 3770K
32GB Dual-Channel DDR3
Gigabyte Z77X-UD5H
3071MB NVIDIA GeForce GTX 780 Ti
232GB Samsung SSD 850 EVO
ASUS Xonar DGX Audio Device
FSX
PMDG 777
Active Sky Next
PRO-ATC X
I been trying to find out why the 777 freezes during flight. (Sim freezes, sound goes in a loop).
I have done a lot of flights with different parameters in the fsx.cfg.
The parameters which I used was found in various forums and webpages.
In the beginning I did believe that the VAS memory usage limit was exceeded, but that was not the case.
For a couple of days ago, I stumbled over some post's about "videomemoryoverride".
Things started to get very interresting during the test flights when trying this new command in the fsx config file.
I first tried a setting with 1GB, and I was able to fly for about 1 hour before it froze.
Then I used a setting of 0,5 GB or 512 MB and voila, I could do transatlantic flights which had a duration of 9 hours and still no freezing. :smile:
In the last couple of days I have flied 3 long flights, and no freezing. :smile:
The flights duration were:
-9 hours
-4 hours
-3 hours
-----------------------------------------------------------------------------------
Here is how it is done:
[DISPLAY.Device.NVIDIA GeForce GTX 780 Ti .0]
VideoMemoryOverride=536870912
You put the line in the graphics card section.

I hope this info can be of interest to others which experience the same problem with freezing. :wink:
Best regards
