64 bit OS and PMDG aircrafts?

Recommended Posts

HiI'm planning to switch to 64bit OS, and could somebody tell me what I could expect with 64bit OS.Also which one do You prefer, XP64 or W7 64.The main thing is fs9 stability and compatibility with payware a/c and scenaries.I don't care about visual look.Thanks in advanceEdin

Yes maybe Win7 64 is a stable system as Ryan says. Will get that OS when I buy a new puter this autumn. But I will also install my XP-64 on that new system, just to be safe, that

I've had no problems with Vista 64 running both FS9-10. W7 would be the way to go now, but I am waiting for my work to pick back up first.

I just purchased WIndows 7 Ulitimate 64bit and I like it. I had a couple of kinks for some really odd reason and after 3 days of days working on it i got it going and its runs nicely. For some reason, if someone could explain why this happened, on my first clean install of Windows 7 I couldn't install itunes(I spent 5 hours looking for a reason) then on the second clean install of windows (FSX was crashing) and on the 3rd clean install it all worked(3rd time is a charm?) Windows 7 in general is the way to go but 64bit will love your PMDG. You should not get any more out of memory errors as I read in this forum and so far I haven't. Other than those 3 clean installs I have had 0 problems.I also suggest putting FSX on a separate hard drive.Taylor Oldham

Thanks guys.One more question.In case of installing 64bit OS, should I Use CFF Explorer to set the flag in FS9.exe?Because I read that without this procedure 64bit OS is useless , with whatever RAM you load in it. http://forums1.avsim.net/index.php?showtopic=270471And now I'm curious , should I expect again problems with AES as I had it with 3GB sw after changing fs9 flag.Edin

Hi Edin, I have Vista 64 and am also one of many that have a disappear textures issue, that people have cleared up switching back to XP64. If you have a lot of adds, I would just go with XP64 honestly. I am actually about to downgrade myself. Win7 has the same issue from what I've read but have also read some good things. If you do go to either Vista or 7, do yourself a favor and install your FS other than the default directory, anywhere but Program Files (x86) anyway, that may lead you to some nanny Admin rights issues.

Really? I went from XP Home Prem 64Bit to Vista 64Bit (for like 1week) then got my disc for 7 64Bit. I dont have any issues with FSX in Win7 except for a bottleneck (but thats not because of Windows) I found in the x86 directory not much different to XP's Program Files.

Like I said, I don't have it, but have "Read" lot's of the same Vista issues that I experience often.As to the x86 directory, again I go by the many posts I've read about admin rights, because Vista and 7, safeguard it and make writing to those files sometimes difficult. I never install on my OS drive anyway, but giving advice from what (as I said) I read, and I think is good advice in general anyway, but thanks for your opinion also.

Hi Dan and others and thanks for valuable information.I think I will go for XP64, because I want reliable solution.Still W7 is new OS, so maybe with new PC :-). Is it problem with x86 directory vissible on XP 64 or..?Also, nobody confirms that I must Use CFF Explorer to set the flag in FS9.exeAnd another question. I have 2 identical HD 320gb, and I had RAID0 on my XP32bit.In Your opinion what is the better solution, make a RAIDO or normal array with 2 identical HD, and then install FS9 on that second HD. Edin

I have run normally run my system with Raid 0 up until about a few months ago. Even with my drives (2 WD Velociraptors) in raid 0, isn't going to give you much for gaming as most people think (if anything). I liked it for video editing but no longer bother.Running your FS installation and add-ons on HD by itself has it's benefits though, and that's what I do currently.The x86 directory thing is just the extra contol Vista has on it (Thus the nick name, "The Nanny"). If you look around you'll read tons of people not able to do certain things without first running it as Administrator. I just don't like the attempts for control MS has done in the last two OS's and only thing I would recommend 7 for is if you want it to change your wallpaper on a schedule. I have installed it on a couple comps I built (per request) and it does boot fast and installs with no prob, but other than that don't have any experience with it (minimal).To each their own.

I am one of those who tried Windows 7 Ultimate x64 and had a bloody nightmare with black/disappearing textures and CTD's on long (4+ hour) flights. My final conclusion was it has something to do with the combination of my rig and how the newer Vista/7 kernal allocated RAM and GPU memory. Since switching back to my tried-and-true WinXP_x64, I have not had one single texture loss, black-screen, or CTD. I won't look at Win7 again until well after the first service pack is released for this OS.Don't get me wrong, I liked Win7; I have it running on all my other computers in my household - it just couldn't stand-up to the rigors of my full-blown FSX environment. YMMV...

One thing I wonder about the vista64 and win7 texture disappearing act (dawn/dusk), is if it's only nVidia cards. If both Ryan and Dan D, recommend it both with "no issues", then I take it they don't share this anomaly, and I notice they both have ATI's. If that's the case and you have or plan on getting an ATI card, then 7 is probably not a bad choice. But I'd research a bit to be safe. One thing I do in my spare time is do custom builds and I actually just got a call this morning from one of the comps I recently put 7 on, asking me to take it off and throw vista on there? Not sure why yet, but if the choices are between vista and 7 only, then I would say 7,,, I think this guy's tokin on the wrong pipe.

Thanks guys.I'm going to XP64, because I think it is more reliable for fs9.Today I have hard work to do with installing fs9 and addons.One last question about memory usage on FS9.Hypothetically, I'm flying with MD11 above huge VFR scenery, and mem usage is around 1.4Gb and rising.After passing this scenery I'm above ocean (only water textures), should memory usage go down??Because in my case I try flight from EDDF-KATL, and somewhere above EGAA (Belfast), memory usage start to go up very quickly from normal values around 960000, and goes up after passing EGAA (UK 2000), even when I was above ocean. Then fs9 OOM happened with mem usage around 2.0Gb. I have 3gb switch activated.Edin

Hi Edin!If you are going for a 64-bit OS, you should have at least 4GB of memory. I have XP-64 Prof using UT-texture for Europe, US, Canada and Alaska and lots and lots of Purchased airports including landclass and mesh for the whole world. I usually have up to 2,1GB of virtual memory when flying long routes, over those areas. When passing over waters, my virtual memory usually goes down but only very little to 1,8GB, but it will not rise either.But if I

Hi Leffe.Thanks for great explanation.I have 4GB of ram, so I hope it would be enough.I will do it like You explained.How big should be pagefile?And on 32bit Win, OOM happened with Virtual Size of below 2Gb.Thanks againEdin
Yes in a 32 bit OS, OOM usually happends to me at around 1,6 GB of Ram. Had it not patched though and only 2GB of Ram that time.The only thing you do after installed the new XP-64 is to patch the Fs9.exe file....d/l the above utility and checkmark it, can handle >than 2GB as shown inthe pics.

Leff, I thought we went over this already? http://www.simforums.com/forums/forum_posts.asp?TID=29041 it has nothing to do with the OS. Vista and W7 need it to.Hi Edin,You received most of your answers below just to add my 3-cents I recommend that you precisely follow this information posted here word for word: http://www.simforums.com/forums/forum_posts.asp?TID=290411) Just to be clear FS9 requires CFF patching to allow it to use greater than 2GB memory regardless of what 64-bit OS you choose.2) XP-64 is the most stable platform for FS however:a) XP is antiquated and many software developers are no longer making XP-64 drivers.:( W7 should be the system of choice. Many do not have issues with W7 and FS however some do. If you are one of the ones that do then you are in trouble.c) I use XP-64 and will not change unless I must.d) W7 is the right choice as long as it doesn
