Pushed it a bit but was realistically hoping it would not fail

 

From KPHL (Sunskyjet) to FSDreamTeam's KJFK with Aerosoft's Manhattan X; AXE; JFTraffic360 at 35%

 

screen resolution was  (3 DELLS)  = 3150x1680 eyefinity

HD7970 3G videocard

 

FTX Global and Vector (update

 

ASN with REX4 (4096 graphics)

 

cloud shadows draw to 20km

(100km and max density in settings)

terrain shadows 20 km

 

veg and bild dense

 

fps a constant 16 on final

 

after landing....

VRAM maxed at 2.7G (400 for win-7.64 etc.)

RAM usage maxed for P3D got to just above 3.2G before calling the OOM flag but was able to continue to the ramp

 

That was a whopping 5.5G max usage for P3D

 

Solution: do not use 4096 textures, might work well with 2048

 

anecdote: FSUIPC was able to save the situation at the ramp from an autosave... sort of a complete flight then

You asked for it! Lol

 

Did a similar test flying over the Nyc/NJ area with nycx and fsdreamteam jfk....

 

.. . Flew about an hour with everything maxed (no shadows except cockpit)... and not a single OOM.

 

And.... Flying up to the city from jfk.. . the whole skyline was in view and never dropped out once.

 

Previously, that flight lasted about 10mins before OOM and all soughts of texture issues.

It worked out pretty good actually, considering the settings

 

Anyway, the act of only reducing the texture max to 2048 was sufficient to replay the trip without even coming close to any  OOM 

 

And the view from far out is amazing !
