I cannot believe that all this posts are about a problem that the OP does not have...

I would say VAS management is very good , it never OOM when the VAS usage was getting high...

Looks like his hobby is to constantly check P3D performance not flying...

Ray, I would advise to provide us with some information about your settings. Stating that your settings resemble Rob's high-end settings doesn't reveal a lot of information. If you don't want to upload images, you can also post (or attach) your p3d.cfg. For example, what is your LOD setting?  That setting has a huge impact on VAS, and setting it to maximum in P3D is equivalent to a value of LOD=6.5, while maximizing the slider in FSX only gives 4.5.

Please post details of your rig.

Intel i7-4790K @4,7Ghz (all 4 cores)
16GB DDR3-2400 CL10
EVGA GeForce GTX 980 Hydro Copper
2x Samsung SATA SSD
Corsair Professional Series HX850i
(CPU, Mainboard, and the GTX980 are watercooled with a customized cooling system)

I use P3Dv3 with 1440p resolution, ORBX Global, Vector, OpenLC Europe, Freemesh X, AS16 and UT2.

I'm using the NVIDIA 381.89 driver and it seems to be working pretty well, though I've not done any real testing on it.

Generally speaking I don't suffer from OOM issues, and the only way I could beat the DXGI issue was to go back to P3D3.35.

Since I only fly high-end third party commercial aircraft, my graphics settings are roughly 1/2 to 3/4 on various settings/sliders.  I don't use the HDR/shadows - somewhat meaningless for me in the commercial aircraft.

i7-4770K x4 cores at 4.3GHz.

GTX960, pushing x1 55" 4K and x3 23" monitors.

 

Best wishes.

I disagree. When you pass from land to ocean why is the VAS not being recovered? And if I approach FSDT JFK2 with only 500Mb remaining how can I be sure I will have enough VAS for a landing?

As I said earlier FSX could recover VAS after leaving an airport. P3D doesn't appear to do that. It might be the drivers or it might be P3D. I've only had it 3 weeks.

I'm not a hobby tweaker. I set settings and leave them alone. Life is too short.

Hi Ray, not to sure if you were using DX10 in FSX which  handle memory better than dx9 by off setting it to the gpu. maybe dx11 can't do it as well. don't know .

just a though have you turned Shader cache off in the NVidia control panel as this has been reported as helping a little with vas.

Hi Bob,

No, never bought DX10 Fixer. I've turned Shader Cache off, it was on. Thanks.

I have a test scenario with the Cub positioned over T5 at Heathrow pointing east so the whole airport is visible. Ai is limited to 150 and zero wx. In Locked Spot view the available VAS with settings as in my P3D.cfg above is 1519Mb.

If I move all sliders to the left in Scenery, Lighting and Traffic and turn off any options selected and then save and reload P3D the available VAS is 2530Mb. FPS is 125.

I'll gradually add back those settings and see which has the greatest impact.

Hi Ray, you could try altering this to 30 and restrict/lock your frames. This may have an impact on texture loading, of course this depends whether LM altered the coding from fsx to p3d.

Hi Bob,

The overall consensus on this appears to be to leave it to unlimited. I would imagine LM have changed quite a bit to do with texture loading and unloading.

I have dropped Scenery Objects settings back to Dense for Complexity, Autogen veg and Buildings. Very Dense is probably responsible for VAS consumption even if it didn't impact fps.

Ignoring all the scenery settings in P3D. I'd just like someone to explain this to me please.

I loaded the Cub and positioned it over T5 at EGLL at 2000ft on a heading of 045. I slewed at 320kts for 10 minutes. Stopped. Turned to a heading of 225 and continued back towards EGLL at 320kts. I overflew EGLL and stopped the test around 4 minutes later.

This is the graph showing VAS consumption. It is going in one direction only. Why? Why isn't P3D releasing VAS as I pass complex areas? This is the essence of the problem, not my settings in P3D.

Incidentally, it also includes this line which appears to make no difference whatsoever...

ENABLE_MEMORY_OPTIMIZATION=1

Ray .... 

 

The bottom line is ... are you suffering from OOM messages which are interfering and stopping you completing flights? 

Paul 

Hi Ray,

Pulling your hair out yet? If so, I wouldn't blame you as we've all been down this road at some time or another and know only too well what you are experiencing. Many of these are System specific and may not help you. It can all get a bit confusing when assailed from all sides with suggestions and/or 'recommendations'. Don't forget you can always get back to the sim's pre-tweak default state by renaming Prepar3D.cfg (preserves your previous settings for reference) and deleting the Shaders folder (NOT the ShadersHLSL folder in Prepar3D root. There is a strong case for starting again and building up your settings bit by bit while witnessing the effects produced by each change.

I noticed you are using AffinityMask=255 with HT=ON (11,11,11,11). Actually this entry is not needed as it's the same as AffinityMask=0, the sim's default setting. When you have time to explore this setting a bit further there is no better resource than Steve Waite's excellent article over at his CodeLegend website:
