Did a trial flight with Majestic Dash 8 KPSP-KSEA. All sliders to the right, except shadows. Full ORBX package with default ORBX KSEA, and ASN16+Clouds.. P3D crashed on 5 mile final over Seattle scenery. Obviously 8 gigs of video memory not enough :)

The card memory has nothing to do with the crash! FSX and P3D are both 32bit so they can't use any more the 4GB. You could have a 50GB video card and you will get the same result. Maxing out the slid

No, it's the fault of P3D being a 32 bit application, same as FSX and FS9, although P3D can make better use of the allocation, it's still 32 bit.   You've been here since 2011 and I would think that

Very much doubt that was because of maxed VRAM.

 Then you should doubt LM message box as well since it stated upon exit that P3D ran out of memory

That kind of sucks I have memory but can use it :(

I can't kill my eye candy. Gotta back up on sliders.

 

By the way since P3D was not freshly installed with new video card would it make sense to do something with shaders? Renew them perhaps?

You ran out of Virtual Address Space, not VRAM.

 

Cheers!

Yes you can.

Just keep adding monitors to your system and you will eventually use up all your 8 GB of VRAM.

But your crash was probable due to to lack of VAS (Virtual Address Space) which has nothing to do with VRAM.

 So is it OS fault then?

 In other words, no hardware can manage full load LM graphics  + ORBX?

You've been here since 2011 and I would think that in reading the forums you would know the limitations of 32 bit sim as it's almost discussed daily here.

Yeah, as mentioned a few times now, this has nothing to do with VRAM. Nor the OS's RAM management. This is the application's virtual address space, nothing else.

Correct.

 

If it is still unclear, the memory in question, that P3D ran out of, is not the VRAM soldered on your GTX 1080. It is the RAM inside your computer, the memory "sticks" on your motherboard. As the others have stated, P3D is based on a technology can only make use of 4 GByte of that RAM (so don't bother buying additional RAM modules with P3D in mind if you already have 8 GByte or more in there). If the P3D program needs more RAM than those 4 GByte to display additional objects, clouds, aircraft etc. it will produce the aforementioned error message.

As a rule of thumb, never fly a complex aircraft onto a full-fat Orbx region. When flying PMDG or Majestic it's more sensible to use FTX Global.

 

As others have said, its not your card.

One can monitor the GPU with GPU-Z a freeware tool very well. I doubt that your card run out of memory.
