Prepar3D v4 Compatibility And PMDG Products

With the move to a 64 bit environment I hope devs don't decide - "its 64 bit so we won't bother optimising our products for the least amount of VAS usage". Although VAS and OOM's are pretty much out of the question now, for those that are running lower than 8GB of RAM it is not. Will you (PMDG) continue to optimise your products to use the least amount of VAS possible and not overload your aircraft with VAS eating items? 

I don't think they would just disregard any optimisation, first as long as they are developing for both 32 and 64 bits which I guess will still be the case for sometime, they will need those memory optimisation, and as I don't think there are doing a complete rewrite for 64 bits, a good part of the code base is probably similar for both 32/64 bits version.

Also just as a matter of fact you won't see a crash at 8GB if you have only 8GB of RAM. OOM occured because of the lack of possibility to adress more memory with 32 bits addressing system. With the 64 bits you can access theorically exabytes of memory, so if you were to run out of the physical RAM, Windows will then start using the SWAP memory (basically using the HDD as memory), so you should not see right away OOM until the HDD is full or the SWAP memory size limit is reached, which gives some margin above the RAM memory you have ;)

That is reassuring, I was considering upgrading to 32GB from my current 16GB of RAM, but as a couple posts before this stated, we will wait and see how P3D V4 uses the memory. However, I will be upgrading to a 1080Ti to take advantage of much better settings within v4 as my once tank 780Ti isn't so much of a tank anymore in todays simulators.

Yes and I would not worry too much because today there are OOM but they take some time to happen with 3GB of RAM usable by the sim, so with your 16GB I don't think you'd be having an issue very soon either. I'm on 16GB right now and I4ve not planned to change. I4m already on a GTX 1080 non Ti but I think that is more than enough :) I'm really looking forward the change as it will be the big jump from FSX to P3Dv4.

What do you think of P3D v4? Is it worth to change vom v3?

[simtom 495]

I'm still using FSX: SE and I'm not sure what to do now. 

I only have the 747 QOTSII and Active Sky Next add-ons that are simulator specific. GSX is cross compatible, right?

Is the performance leap between FSX and P3D significant or not really? I have a 1070 so maybe that will make a difference since P3D uses your GPU more than FSX.

Uses the GPU more than FSX, but not fully like modern games, and so on...

The performance jump from P3Dv3 to v4 easily gave me a decent increase in frames for equivalent settings/areas (not going to be specific since an exact number would only be good for someone with the exact same comp as me). It's definitely smoother, as most of the team has noted.

Hi Kyle, do you think I'd see some improvement in that area as well?  Seriously considering P3Dv4 once all my favorite add ons are ported and working.  I have a GTX970 but do have money to upgrade a simple component.  Although I'd imagine my system is pretty balanced between CPU and graphics card.  Certainly won't worry about system RAM

I see, that's what I wanted to hear ;) 

But I'm still not sure if I want to spend $199 just to have better performance. I know that more frames will give you a smoother game experience but the price tag is a bit steep for me (I'm still a student). 

This also means I would have to repurchase the QOTSII, which is also more expensive than the FSX version.

I'm not trying to blame anyone here, I just think that P3D is a bit overpriced. Or perhaps this has to do with P3D not being a true flight simulator, right? It also simulates ships, if I'm not mistaken? It's basically a simulator platform then.

Good news the 747 will be available so fast! Just upgraded to 32gb of ram, cant wait to see the improvements over p3d v3.

[Brit 3]

Can you have both v3 and v4 installed at same time?

Yes, all versions of P3D can coexist on the same computer. Confirmed by several beta testers.

Having said that, I don't know whether all addons will work simultaneously on one computer. Some developers such as Orbx have confirmed that they will.

[downscc 1,327]

The PMDG products can coexist with any combination of P3D, FSX and FSXSE but I'm not sure they will install to P3D v3 and v4 at the same time.  That would changes to the installer and Operating Center and separate instances of each version for things like liveries.  Might get messy and I don't expect PMDG to want to accommodate something like that. It will be interesting.

Good news, thank you for the fast response to the community.

Now I just don't know how I'm going to handle the sim without FSUIPC...

Even more good news: http://forum.simflight.com/topic/83388-fsuipc-sdk-64bit/#comment-503251

Apparently he's running FSUIPC 5 64bit with v4 already.

I was worried about that too.

Yeah, after we got the information that there will be FSUIPC5 very soon after V4 comes out along with PMDGs,ORBX,AS16,etc.... I immediately uninstall P3D V3 and everything from FSX:SE. Will go straight for V4.
