Is that what you all are talking about?

Is that what you all are talking about?

No, A 64 bit OS can run either 32 bit or 64 bit apps. People are asking why P3d2 is still a 32 bit app. What this means is that under 64 bit Windows, P3d2 can only access 4 GB of RAM (or virtual address space if you are silly enough to run 64 bit Windows with less than 8 GB of physical RAM.)

The OOM problem wasn't because of 32bit and addons.  It was because of FSX.   Lockheed has been making products that lives depend on since before most of our Parents were born.  I think they can handle memory cleanly in a 32bit app.

 

I don't think I've pined for a program more.  Not even MSDOS 2.0.  64bit wouldn't make me want it more.  4GB ought to be enough for anybody.

+1. I have never had an OOM error with P3d 1.4 and it is crippled with DX9 which is a bane to memory management.

+1 also - never an OOM and I run sliders maxed, FTX Global, and all sorts of stuff

Again I ask what about the 100's of improvements that P3D v2 offers over FSX? You are just going to ignore them because its not 64 bit? Its extremely short sighted.

 

I jumped into this senseless conversation due to the fact that you called the OP an XPlane fanatic and that made me wonder what led you to believe that, that's all.

 

Don't have FSX nor do I have P3d v1.4 installed. I'm a XPlane 10 user, so I can't talk about FSX vs P3D v2 improvements. 

 

P3D v2 will be a success and as long as you don't overload it with scenery/addon's, I think OOM's may be a thing of the past.

 

 

profound improvement is of going to 64 bit

 

There is NO profound improvement in terms of performance, but it does make a difference when 64 bit breaks the 32bit 4gb VAS barrier and lets you access quite large amount of RAM, Windows 7 ultimate can access up to 192gb in a 64bit environment, so your 64 bit app will have that much ram available, if of course you have that amount installed.

DirectX 11 will only do so much, even though LM has manage to balance the load between cpu and gpu, the fact remains that once you start shoving p3D's directory with a bunch of add-on's and increase eye-candy, you will experience OOM's, garanteed! 

 

DirectX 11 is not the solution to OOM's, 64 bit on the other hand is. 

 

unless you are in the beta how can you 'guarantee' this? all of this is simply speculation. 

 

it's completely possible to write a 32 bit app that does memory management correctly. the OOM's are a fault of buggy coding that doesn't correctly release unused memory, that has nothing to do with the number of bits used. whether LM has fixed or improved this stuff remains to be seen but we'll know for sure in a few days. i personally would rather have a memory manager that works correctly than have one that is broken but it doesn't matter because it can leak over a much larger pool.

AMEN,

 

you can get OOM's in 64bit as much as in 32bit, lets please please please dispell this strange notion on these boards that a program has be 64bit to be good. Have a look at the PC gaming market which is still the largest gaming market and look at how many games (And general software for that matter) are 32bit including all of the recently released blockbusters.

 

64bit is nice, it can offer some extras but a correctly optimized 32bit system can certainly do enough to keep us simmers happy for a fair few years yet.

 

thanks,

If there were a P3D 64 bit version, half of the addons that are memory heavy (i.e. likely to cause OOMs) wouldn't work anyway! 64 bit is not some silver bullet that will magically fix all of FSX's problems.

 

There are plenty of complicated games out there with stunning visuals that run perfectly well in 32 bit. How? They manage the memory efficiently, and that would make much more of a difference to FSX than 64 bit.

 

My understanding is FSX cannot unload anything from memory once it's put it there, so every single thing you see or do in FSX stays in the memory until you exit the program. This is why longhauls are more prone to OOM, every single addon airport you fly near gets loaded in to the memory, and as you fly between scenery regions all the textures no longer in sight are still sat in the memory space.

A 32bit OS uses a max of 4GB ram, including that of the graphics card.

A 64bit OS will use all the ram.

A 32bit program in a 32bit OS will max out the memory -- OOM issues, no matter how much RAM

A 32bit program will see a max of 4GB ram.. No matter how much ram in in the machine.

A 32bit program in a 64bit OS will let the program use up to the whole of the 4GB ram + the ram of the graphics card + give extra ram space & headroom

 

Very simplistic, but I think explains.

Lol.....

 

So let me get this straight.

 

You are an xplane only user in the p3d forum talking about OOM in fsx and p3d like you are a user yet in reality you have no experience with either?

 

Then you actually take issue with my use of the phrase "xplane fanatics"? Honestly, you couldn't make this stuff up........

You are an xplane only user

 

lmfao!!!

 

Do you mind pointing out where I posted the "only" word?

 

Everything about OOM's its here in the FSX/P3D forums, and  by the way just so you know, I DO have them both, just not installed. 

 

No point in continuing this senseless conversation, you WIN, lets move on.

I agree. The question was asked and answered correctly in the first reply. Everything that's followed has been hashed and re-hashed ad infinitum, ad nauseam...
