Er… at first I though your post was enlightening but after reading it twice I am totally confused LOL

 

Maybe someone can post a RAM-guide for newbies?   The way you say it makes it seem to me that you only get an OOM-message when the VAS has been filled… so this has nothing to do with RAM…? But isn't there also a physical RAM limit of 4 GB? Don't you get an error when that reaches 4 GB then? Or do you only get an OOM when physical RAM and VAS has been filled which would add up to 8 GB before you get an OOM? And where does VRAM fit in here? Does whatever doesn't fit into VRAM get moved to physical RAM or VAS…? As you see: total confusion.  :blush:  ^_^

 

EDIT

Here is a picture I made of how I currently see it:

 

 

Presumably that's you in the middle?  :lol:

Presumably that's you in the middle? 

 

 

That's exactly how I feel right now, yes.  ^_^

 

@Oliver, thanks for the explanation. I still don't really get it LOL You totally surprised me when you said your FSX RAM usage goes up to 6 GB… so I think my understanding of what VAS is, is totally wrong. I'll have to have a talk with my good friend Google, I think.  ^_^

P.S. AffinityMask automatically sets Core 0 free only when you use a 6-core CPU or higher.

 

I dont get you.

 

My 4 core CPU automatically leaves Core 0 for the OS etc, without using any affinity mask setting at all. P3D V2 does this by default as confirmed by LM.

 

 

 

V2 is smarter about generating its default affinity mask, but if you want to tinker with it yourself you still have to add the entry to the config file. P3D is still better off with one thread per physical core, so it generates an affinity mask that puts one thread on each physical core of a processor. If you have 4+ physical cores, the application will bump itself off of the first core to free up the processor for the OS and other applications. Thanks,

Well this is how I understand it...

 

It doesn't matter how much VRAM/RAM/SheepRAM you have, if P3D uses more than 4GB of memory during operation, it will OOM. The constitution of your system (ie how much VRAM & RAM you have) simply affects how it will perform, rather than anything to do with OOM.

(...) You totally surprised me when you said your FSX RAM usage goes up to 6 GB… (...)

 

 

Sorry, I was unclear there: I can run FSX with a number of external addons (*.exe's like weather, VoxATC etc.), so the combined usage of physical RAM exceeds 4 GB. Still every single 32bit app running has a VAS limit of 4 GB each.

 

Reaching 6 GB of physical RAM happens with the VoxATC voiceserver *.exe running, an external application needing 1.2 GB of physical RAM on its own.

Ah, got it. I am beginning to understand it, after also reading for instance http://#####.wordpress.com/fsx-oom-and-addon-vas-usage/ and http://superuser.com/questions/332564/virtual-memory-vs-virtual-address-space

 

P3D, as any 32 bit program on a 64 bit OS, simply has 4 GB room for data which is the virtual address space, VAS, and the OS takes care of how this is actually spread over physical RAM or a page file. I think I was confusing the page file, virtual memory, with virtual address space and I was also thinking it mattered how much physical RAM or page file was used. But that doesn't matter at all for P3D: it only sees that 4 GB of VAS. Got it. 

 

​With the knowledge I will do some testing this evening to find out what exactly floods my VAS!

 

I now also see how P3D 64 bit would help… and I don't really understand why some say that doesn't make a real difference. But well, P3D 64 bit won't happen any time soon so I will have to get a hold on my VAS. Still it surprises me that we have these problems as I presumed LM would have fixed this so a certain point. 

 

​Anyway, to get back on topic: How is it? A bit of a mess right now…  ^_^ 

Yep, the confusion usually starts with the virtual memory/virtual address space terms being so similar.

 

Process Explorer from Microsoft.com (for free) to measure VAS during your flights.

 

And what is, BTW, ""P-r-e-p-a-r-e-3-D"?!?   :lol:  :ph34r: 

Jereon, if you have registered version of FSUIPC , you can monitor VAS usage in sim with logging and displayed either in SIM or on menu bar.. helpful little tool.

I NEVER thought in the world that I would see the 'This Topic is now being monitored, etc' from within the P3D forum.  Wow.......

 

I remember the excitement that preceded the launch, as was the same for Flight. It's happening all over again.

 

Happening all over again....what a shame.....

That feature's available in the unregistered version too.

 

 

Please take a thorough look at both his performance analysis and autogen comparison, and then try to prove me wrong. What's he's posting is the actual results.

 

blah blah blah blah blah blah blah blah blah blah... 

 

You still haven't replied whether or not you own and have installed the Prepar3d V2. As someone already reminded you, the thread is titled "How is it?" not "How you think it will be based on someone else's blog"

 

Right now you're providing a lot of chaos and no beauty, quit fogging up my AVSIM windshield

I deleted FSX in frustration after a bunch of BEX/APPCRASH errors started occurring suddenly after 2 years of having it run flawlessly preventing it from starting anymore.
So P3D is pretty much sim or no sim at all for me at this point. I'm done with FSX forever.

I definitely was skeptical about this product even installing correctly without errors. 

The whole process ran smooth and easy.

Just installed V2 and got everything up and running no errors no OOMS no crappy FPS micro stutter all cockpit clickables work great also.

Very fluid smooth stable 30FPS with all sliders maxed out except Shadows which are on Medium.

Best of all I didn't have to fiddle with any Nvidia Inspector or cfg crap at all to be satisfied with the looks ingame.

I honestly never cared much for REX either just more stuff to load the game down and rob FPS so Ill be doing without Rex for now I always hated the way REX loaded in weather to my sim always broke immersion for me.

You guys really wanna see some eye candy???

Fly outta Princess Juliana late evening and enjoy those lush tropics and beautiful warm looking coastal waters.

Being a 3DVision enthusiast what really made the P3DV2 purchase was that LM are working with Nvidia for the 3DVision support and hopefully when a better Occulus Rift releases the 3D/VR wizards will conjure up the configs to work with P3D also as they did FSX!

 

Only thing I'm hoping for now is compatibility with FSRecorder(because I like to fly with my AI recording in formations) Ill give it a try to see if it will work.(Fingers Crossed!!!)

I also now have a reason to purchase FTX Global in which I was just about to do before my FSX started crashing.

 

Also for you potential 780 buyers I see all this 780ti talk you can get my version 780 for cheaper and it has better clocks than a reference 780ti.
My EVGA ACX 780 runs great cool and quiet and has eaten everything I've thrown at it so far I haven't even bothered to overclock it,

the default clocks are more than enough to handle everything I'm playing.

This release is nothing like Flight. 

 

CB?  Why is it so hard to just say "yes" or "no" in regards to whether you, personally, have installed and tried P3Dv2?

 

It's really a simple question, and not answering it is just as discrediting as answering it with a "no."  So, if you actually do have any experience beyond reading someone else's blog commentary to discuss, please do so.  We are interested in hearing it.

I'm gonna actually go ahead and send a request to have a mod take another look.

 

You've been nothing but an irritant since your first post n this thread.

 

It seems that you do not own P3D2 and have no interest in owning it, and are only here to speak for Word Not Allowed ? or something, really not sure.

 

If the only point of your posts is literally to be argumentative, then you can take it somewhere else.

 

Congrats on likely getting the thread locked though. Very well done.
