I finally installed the actual RTM Windows 7 Ultimate x64 yesterday and I'm happy to confirm no issues with any of our products in either FS9 or FSX.I had a strange issue with FSX itself, but I think it may have been related to UAC and a reinstall using Run as Administrator fixed it. Par for the course with the Vista/7 architecture.Performance is very good, on par with XP to me and definitely better than Vista was.I'd recommend basically everyone upgrade to 64 bit Home Premium, Professional, or Ultimate when the general public release happens October 22nd. It's a very good OS and will solve most of the OOM/CTD issues people have had using 32 bit XP and Vista.

Good to hear Ryan. One question: why do you recommand the 64bit version when FSX is build for 32bit? Has 64 any advantages above the 32bit?

Hi RyanI also use win 7, but i have one problem. When im running pmdg 747 the game freezes at various stages with high settings. If i reduce my settings to low it runs without any problems ?? AT LOW SETTINGS I RUNS WITHOUT ANY PROBLEMS !I think its very strange because my computer is pretty good.Win 7CPU: intel core 2 quad q6600 2,4 ghz4 gb ram32 bit OSNvidia 8800 GTX At low settings my processor use about 700.000 kb according to my taskbar and have CPU use at 50 % and it runs as i said before without any problems. At high settings it uses about 1000000 kb according to my taskbar and have CPU use at app. 90 % and it freezes everytime !It is very annoying. Is the game too big for my computer or what is wrong ??I know there are many posts about this issue, but its all with Win XP or Win Vista. I hope you have some kind of solution. Or maybe you know a computer genius who can explain this problem.Regards Kim

I've been running windows 7 64 bit for a few weeks now - FSX runs faster in it than it did in XP 32 bit, by a fair margin. Default aircraft went from 35-40 fps in XP to 90-130 fps in Win 7, the heavier addon aircraft didn't see as much of a jump but the Mustang went from 15-20 fps to 20-25 fps which helps. Realair Duke went from 20-30 fps to 30-40 fps.

Is it true to say that, in order to use Win 7 64-bit OS, you MUST have a 64-bit processor?

Excellent news. I have been waiting for some reports on Windows 7. Do you have any preference between Home, Pro, or Ultimate for FS9 use? Thanks for the post. Great info.Fidel

Correct X86 vs X64. A 64bit system will run a 32 or 64bit operating system but 32bit hardware cannot run a 64bit OS and you have other things like memory limitations. If you can, I would highly recommend an upgrade if possible. Being able to throw 6 gigs of ram into a box running vista sure helps.Here is a great article you can read if you have more questions:http://windowshelp.microsoft.com/Windows/e...5c8a701033.mspx

Thanks for the link. Unfortunately my computer is just 2 years old, so I have to wait one more year for a new setup. I downloaded the 32bit version, so I think I will install it when the J41 is released. A clean install for this nice little bird!

FSX is a 32-bit app correct, but if you run Win7 64-bit you do not have the limitation on User Virtual Address Space, which is what causes the OOM errors in the 32-bit OSes. It's an OS thing not specific to the app/game being run. Aside from this you can use all of your RAM - no Core i7 system should have less than 6GB and you'd end up wasting almost half of that if you used 32-bit Win7. It's very likely that we'll place a 64-bit recommendation on the new NG, we're tired of the OOM errors and being blamed for them etc - technology has gone beyond what the 32-bit OS was designed for.

Is it true to say that, in order to use Win 7 64-bit OS, you MUST have a 64-bit processor?

Yes, but this is any CPU from the Core 2 or Athlon 64 series and on. Basically if you've bought or built a new computer in the last 3 years or so you should be fine.

Do you have any preference between Home, Pro, or Ultimate for FS9 use?

Home Premium should be fine for most people. I'm using Ultimate just because I can and it was available to me really. Pro and Ultimate have a few networking and encryption related features that are of use to businesses and something called "Windows XP Mode" that's an emulated XP virtual machine that allows you to run certain old business apps etc. Nothing the average home user/gamer/simmer would need.The one you don't want to use is the "Starter" edition, it lacks a lot of the cool UI features.

RyanHave they fixed the business about having to click in peculiar places before you can get FSX to add scenery properly? I've been using Win7RC for a while and this seems to be the only FSX-related glitch.Tim

Cheers with the 'no problemo' bit Ryan but.... yep always a but lolI'm going to Windows7 64bit myself in October but have a small question... Is fs9.exe ok as it stands or is it not 'large memory aware' like fsx.exe?I.E. is fs9 still subject to a 2Gb limit?John Ellison

I too installed windows 7 a few weeks back and I love it. I completely skipped over Vista because it was such a POS. My only complaint is the amount of resources W7 uses at idle... right now w/ 1 firefox window, AVG, and a couple component applications, I'm using 1.20GB of RAM. However, I also installed it on my second computer (AMD 3000+, 1GB DDR, etc) and it runs decently (I use it as a media center) and only uses about 550MB because it automatically turned off several components of the Aero interface. FS9 runs perfectly on this rig at 1920x1080 and all max settings (I haven't switched to FSX yet).-Peter AllenIntel Core i7 920, 6GB DDR3-1600, ATi HD4850 512MB

Peter,That is normal, Vista as well as 7 have a feature called superfetch. It's basically XPs prefetch on steroids. The assumption is that unused RAM is wasted RAM, so it will fetch as much as possible. I memory is needed, memory pages will be discarded in order to avoid paging to disk

Just to clarify, the same stays true also with Win XP 64 and Vista 64, 7 is no different here. FSX was written with 32 bit limitations in mind, so apart from fixing OOM problems with complex addons that push it beyond these limits, don't expect performance icrease. It normally still stays way below 2GB RAM usage and unloads textures very quickly when you're looking the other way, so dissapearing textures when switching views still happen.It is also specific to app/game, because 32 bit program still has to have the LARGE_ADDRESS_AWARE flag set in exe file to get more than 2GB. Fortunately it's easy to change by 3rd party apps and in FSX it is enabled by default starting with SP2/Accel.

JUst one qestion, im having keyboard problems with the fs9 version of the 737. If i switch between the MS737 all the keys work, when i switch back no keys work? AnybodyWIN7 |Ulitmate 64 with FS9Mike Utrecht
