Agree with Dan.  It is my understanding all 32 bit scenery will work with the 64 bit version.

Took just a few days of mucking around with XP 11 demo  to realize that X Plane was a waste of time. 

Absolutely agree, I mean look at the atrocious lighting (especially at night!), the horrendous performance, the instability (I heard someone had a CTD once), the terrible default planes, the garbage scenery, the lazy community (they don't even bother to charge money for the stuff they make - how rude!). And they even sell it on steam like it was just a kiddies game not a super-serious simulator. What a waste of time. /s

XPlane users are so insecure that they take every opportunity to beat their chests.  I really don't care which simulator you prefer, it has no impact on how I feel about my favorite platform and I've spent plenty of time with all three.

Are you kidding???  This thread is multiple people beating on XP based on a few hours of using it?

I think you can safely change that remark to "Simmers are so insecure..."  P3D users are just as bad as rabid X-Plane users; myself, i have used both sims, i prefer P3D but X-Plane certainly does have it's charms.

I am curious to know why the "memory leak" issue has been so elusive. Is it 32bit ram OS limitations, or software specific, in this case bugs in the sim code.

Hi Tony,

From Wikipedia: "In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released."

Prepar3D, like FSX is a 32bit application and, as such, is resource restricted by only being able to use up to 4GB of VAS (virtual address space). Those experiencing OOM (out of memory) episodes are either running with memory hungry addons, insist on unrealistically high in-sim settings or a combination of both. This potential problem is compounded further by memory leaks, either in drivers (more recently NVIDIA) or application software.

Here is some useful bedtime reading which should help shed light on these issues for you: https://www.howtogeek.com/56701/htg-explains-whats-the-difference-between-32-bit-and-64-bit-windows-7/

In addition to the above, I have found avoidance of OOMs can often be achieved by resisting the temptation to switch scenery locations repeatedly in any one sim session. Instead, plan ahead and devote each session to the one intended flight. This is much less of an issue in lower density scenery locations and the use of stock aircraft.

Regards,

Mike

In Windows, the 32bit Address is not a limit on the use of memory. Advanced techniques available to specially supported MS apps can address dozens of Gb through paging, although it cannot all be addressed at the same time.

An app can ask for more memory than is available and the code fails with no storage, or an app can determine the memory availability before allocation and defer if required or report gracefully to the user or system. Instead if the sim crashes with OOM, this is ungraceful and indicative that something bad went wrong. It's rare that system specifics like GPU drivers cause this kind of problem, more often it is some kind of problem within a model or the way the sim is utilised by poor SimConnect code. Sadly going to 64bit addressing won't cure these problems.

When getting OOMs simple deductive methods usually surface the culprit, in other words going to stock sim usually cures all problems. With FSX this is more than 99% true, but the plethora of clever techniques and ingenuity within FSX based addons and with FSX based on iterations of the product keep all sorts of stuff working fine. However with P3D, changing almost anything in the code could very easily disrupt the intended outcome of these techniques and crash the sim. They have to tread very carefully to ensure compatibility is maintained throughout the available addons and have done a tremendous job, not for the feint hearted.

Thanks, Steve. I just wanted to be sure that part of the issue is in bad coding rather than memory limitations.

Bold statement from a long time member...  I use both sims and it is quite apparent from my screenshots - I sing high praise for both of them.  I am not insecure though... your comment is out of line!  

ANY sim takes TIME and effort.  You can't just try the demo for a few days and make your assumptions.  It took me a few months to get into XP10 when I started three years ago.  Think of the time it took you to perfect FSX, hours of tweaking, learning how to install addons, paints, sceneries.... XP needs that sort of love too!

If this thread continues down the XP path, it will be closed. Let's please stay on topic.

Thanx,

Vic

I didn't start it down the path, but I'll steer it back on course...

P3D 64bit - I'll probably buy it, but if the many aircraft I own don't work I won't.  Also I'm hoping F1's GTN units would work as well.  Scenery should be more easily "ported" than aircraft.

Not quite as we you get to the other side of the fence and the grass is actually greener there is little reason to come back.

Better lighting, totally superior flight modelling its only the addons which keep people using P3D.

I mean if it wasnt for Pmdg and FSLabs why woukd you ever consider using a sim which is actually very poor at simulating the way an aeroplane flies?

Heaven help P3D if Laminar ever convince Pmdg to release a full sim for Xplane...

Yeah I fully agree with you Darren.  I use P3D because of all of my add-ons such as Orbx scenery and, most importantly, my PMDG aircraft.  If I could have the PMDG 737 on X-Plane, I'd forgo all of the scenery as the rest of the X-Plane experience is superior to P3D.  If Orbx scenery was available too, I'd be in Sim heaven!

I guess the P3D bashing by the XP people is going to continue...Figures. 

Some people on here are so defensive, like P3D is their own creation and nobody can speak of anything else; you sound like children. Most of us will use more then one simulator and we'll get the most out of this hobby while supporting all companies that support our hobby, and you'll sit in your grumpy old man chair and fuss about petting issues.
