Calling Rob and other VAS hunters

Recommended Posts

Hi Rob,

 

We are a few that suspect FTX Global MESH to have a VAS memory sort of item.

 

We are also a few at the thread of P3D3.4.9 experience thread that can reproduce a VAS memory hog in

 

at least London

 

Would you mind to do the same test with us ?

 

 

The test is EGLL at 27L BGK7G and monitor VAS all the way from departure to at least TOTRI

 

Note: Take VERY close note between BGK an TOTRI (about 7.1nm from TOTRI)

 

Thanks

 

Michael Moe

Michael, FTX Global is one of two products, a landclass or a vector product... there is no mesh.  Do you mean BPK7G?  I don't see a BGK7G in my LIDO charts, nor does BPK7G have a TOTRI waypoint, it's just a NE turn to CHT thence BPK.

The OP may mean Global 2010 which is a mesh but not an OrbX FTX product.

It's not fsglobal it's p3d. It's always been that way in London since fs2004. Why do people think P3d is some magic pill when it's a tweaked version of fsx.

 

Don't get me wrong it handles vas better in some ways but London always has and always will be a sink hole for vas no matter what different dress you buy the same London hooker

This thread links to experiences shared on the p3d experience thread and how pilots mesh is having an unexpected effect on vas usage around London .A post today suggests this may be more wide spread. I have used this product for years and is excellent .hopefully someone can shed light on what is happening or help someone who is having oom issues . Can give flight details to anyone who wishes to recreate my tests.

Sorry for the mis typing. Yes it is FTX Global Pilot MESH 2010 edition i was talking about and BPK7G

 

There seeems to be some sort of VAS issue 7.1nm before TOTRI. Please test this as it could be a major found. Maybe there is spots all around the globe like this one.

 

I have a 300mb save on VAS departing out of London.

 

Thanks Michael Moe

If anyone has free mesh installed could they try this flight egll bnn bpk lam egmc. Somewhere approaching Lam Vor you will get a vas spike between 150mb default scenary and 300mb with FTX England . Remember ftx eng has its own mesh which is above Pilots mesh.Hopefully we do not get the same effect with free mesh. I am downloading but will take 10 hours on a fast connection.

I dont get the VAS isue with FTX England or OPENLCEU.

 

Only with Pilots Ftx 2010 Edition

Sorry for confusion I am only getting it with Pilots as well my point is if I have  FTX England and Pilots mesh activated in the scenary library surely FTX England mesh should have priority. Either way only way I have found so far is to deactivate all Pilots mesh entries in the scenary library.

To get a rough idea of the relative contribution of the VAS usage of various components, use FSUIPC to display free VAS in the P3d title bar. Then start a scenario and watch the change in VAS as various components (mesh, autogen, AI Traffic, etc. are sequentially loaded). Although disabling the detailed Pilots! mesh will save VAS, that can be said of many 3rd party add ons and sim settings.

 

The point is, that we have reached the limit of the 32 bit flight sim and this limit is caused by users piling on complex addons. P3d has two distinct performance bottlenecks. One is the 4 GB VAS limit and the other is the minuscule single thread performance gains by recent generations of Intel CPUs.

Please have a read on p3d experience last few pages .This is a particular situation in a particular area.concerning sudden spikes in vas . Please don't generalise it with the amount of add ons. The issue occurred with just pilots mesh loaded nothing else .

I'll take a look and report back VAS numbers.

Maybe for you. I never see this. Besides, if it's some interaction between the sim and a particular addon, it's not very likely that LM will fix it. Keep up the good work. If P3d stays at 32 bit, these problems will just continue to fester. Despite what you state, it IS a general problem. I haven't been able to do a long flight with the Triple 7 for several versions of P3d V3.

These are my test results based on your criteria/situation:

 

634b06bb61e819985190415b338a0546.jpg

 

I recorded 4 videos of each test, but the file size is 10GB per test so don't really have time to upload them ... if someone is VERY interested in a particular test, I'll upload just that test.  Video shows what scenery library entries are enabled/disabled and graphics settings.

 

The results are about what I expected.  The mesh, be it from PILOT's or an Orbx Region appears to use about 300MB or so.  In test 4 the VAS did increase by 300MB as I approached TOTRI ... visually I couldn't see why, but based on the proximity of TOTRI to Region A (europe germanic) per this diagram from SDK:

 

4e80ff93db5fea8ad9c891abaaf9cf52.jpg

...which would explain the 300MB increase in VAS.

Thanks for testing.

 

I now consider removing mesh on heavy routes with flat areas.

Don't forget about the interaction with the airport elevation corrections that are a part of the FTX Vector configurator. You might as well also unload all ORBX full fat regions and set your mesh resolution to something a lot higher than 5 m. ORBX scenery is designed specifically to work with Pilots! mesh.

Thanks Rob so far I have not had the same issue with FreeMesh x though though the 300mb spike may have just moved slightly and I am yet to find it

Nobody is doubting this but i dont think you have the picture here  :wink:

 

It has nothing to do with Vector,Regions,LC etc but FTX Pilot Mesh when we talk about  "wordwide regions" It seem to cost about 300MB and you will find that 7.1 nm before TOTRI your VAS will increase at about 300MB at least going east .

 

Now knowing this i might just disable FTX Pilots Mesh when i want to land with en extra margain from EGLL.

 

That is actually also what Rob tested so "we" (that would be me) are quite happy  :wink:  It just a coinsidence that this Mesh for Germany-east europe is loaded at that specifically place near London

 

i do not know what a trip will do from for instance EKCH-EGLL but those 300 MB are welcome and might even ad to enabling Vector  :smile:

 

 

Thanks

You suggested disabling FTX Global mesh and I was just pointing out that you will see anomalies with the other ORBX suite of products if you do that in a piecemeal fashion. It easy to use the Vector configurator and just disable the airport elevation corrections where the default mesh produces an elevation that conflicts with an airport elevation.

You'd need to disable the Mesh and Orbx Region ... can actually be done during flight to recover VAS if one is close to 4GB.  Most airports should have exceptions under FTX Central (Vector tool) ... but not always the case, so results will vary on approach to airport.

 

Cheers, Rob.

You trying to bend over Sam to help Belinda- not wise

You could always disable mesh, FTX Global and regions, and all airports you're not landing at. In fact, you'll save lots of VAS if you simply don't install any add-ons.

 

Interesting observation regarding the edge of global regions. Makes sense.

Yeah , 

 

I use the configurator Editor,

 

So using Tubes like the 777 PMDG i just disable every ORBX regions so only FTX Global is in Command (maybe OPENLCEU)

 

I dont find any anomalies here so far  (disabling FTX Pilot Mesh but i could be wrong ?)

 

At least i now have 300MB to spare

 

So far i am really happy

An update:

 

I manage to get to EGLL from EKCH with about 300MB to spare but i really think 3.4.9 should be performing better.

 

This amount of VAS i seem to recall at least with 3.3.5 and FTX Global MESH installed

 

On the other hand my memory was also using another version of Active Sky with REX instead of ASCA so could just be a "new situation "

ASCA so could just be a "new situation "

 

VAS testing I've done with AS16 and ASCA and REX for sky textures has shown very minor VAS usage (75-50MB) and that was with extreme distances (110mi) and 5 active cloud layers using Full Dynamics in ASCA at 2048 cap in some very nasty weather.

 

You don't need to disable ALL add-ons, just Orbx regions and/or PILOT's Mesh ... I do that whenever I fly heavy VAS usage aircraft like PMDG.  FTX Global and OpenLC and Vector (configured carefully) and 3rd party airports and PMDG aircraft with AS16/ASCA/REX seems to work very well with VAS usage ... no problem completing long 10+ hour flights.  It is important to set your CPU affinity correctly also as that can save on VAS.

 

I did ask Orbx dev crew to provide an option in FTX Central to make it easy to switch into "Pure FTX Global" mode (FTX Global only, OpenLC, Vector) and back to "Region" mode.  Orbx indicated they plan to implement in their next major FTX Central version, but not sure if they were just teasing me or it will be a real option.

 

Cheers, Rob.
