curious if popular addons will work under 64 bit ie Wideview ,Goflight and FSuipc , I guess FSuipc and Wideview would work as they are imbedded addons in the FSX menu, but Goflight ? Allan

Dual booting Win XP 32-64 since XP-64 became available. No problems at all. Win 64 even found and set up my HP LaserJet 2100 by itself.My systems runs FS9 with PMDG's and Level-d's stuff with everything maxed out. FSX is another ballgame. I can run FSX at 20-25 FPS with everything turned down, sliders left. No autogen, global max.My setup is a 754 socket and 3400 CPU, 1 gig corsair memory. I build lots of machines and core 2 duo is faster.I did notice that on the AMD side a CPU with 1 gig of L2 cache seems to run FSX better than 512, even if it's a slightly slower CPU.NewEgg has received a shipment of the new dual socket mobo by Asus for the new AMD FX series, FX 70-72-74. They should have it up very soon.I don't know if this 940 pin socket will be able to use the so called K8L chip or not. If it does it will allow for an upgrade path.I'm told that AMD and MS are working on what they call Super Fetch or something like that, for the 64-bit Vista version. It's supposed to reduce file access times greatly. The K8L has just about doubled the pre-fetch units on board the CPU.I think Vista 64 will come into it's own when mobo makers add enough dimm slots and memory makers produce 2 Gig modules. Corsair is about to do so, at a reasonable price I'm told.I think 4 gigs of fast RAM will make a big difference with FSX.

I can't speak specifically to Goflight & WideView, but on my WinXPx64 machine, FSUIPC3 & 4, and WideFS6 & 7, run great. See my sig below. My best guess is, if they work at the application layer, they should be fine, if they require drivers, then make sure you can locate the 64-bit flavors.Regards...

Just to reiterate what Mike T said, there's really no benefit. I'm typing this on my new Vista 64-bit box, and FSX plays exactly the same as it did on 32-bit. Further, I'm screwed because I can't use my TrackIR 4 Christmas present from my wife since 64-bit Vista will *only* install WHQL signed drivers. If I were running 32-bit, I'd be able to use the XP drivers.The only real reason I can see to use 64-bit Vista is if, for some reason, you plan on running with more than 4GB of RAM in your computer.Neil

I'm confused, your first sentence seems a bit at odds with what you say next. Did you mean to say that the 32-bit version will have better driver support? Or do you think that 64bit Vista will have better driver support than 64bit XP?It just seems to me that for the next year or two, 32 bit apps will reign, and then slowly 64 bit apps will take over.Adam Szofran told me that it is currently possible for FSX to run out of ram because it is capable of reaching and surpassing the 2GB memory limit quite effectively. And, unfortunately, having a 64 bit operating system does not alleviate that since it is a 32 bit app.In fact, I seem to remember that 64 bit OS actually hurts use because it uses larger memory addresses (since it can access more memory), which wastes some space. But take that as idle speculation because I remember neither the source or exact content of what was said.Thomas[a href=http://www.flyingscool.com] http://www.flyingscool.com/images/Signature.jpg [/a]I like using VC's :-)N15802 KASH '73 Piper Cherokee Challenger 180

My uderstanding is that an upgrade license will only allow x64 vista to upgrade from X64 Win XP.scott s..

NeilI would be cautious using a win-xp driver in vista-32bit anyway.

If you don't have Vista drivers available, it's you're only option :) My printer is the only thing right now that's running using the XP drivers (64-bit, in this case), and it works fine. On my laptop at work I'm running with XP audio drivers. Pretty standard practice, until the rest of the world catches up and releases Vista-specific ones.Neil

Hi Thomas,<That was basically what I was trying to say :->And while a 64-bit OS won't help one 32-bit app access more memory, it will allow the OS to run more memory hungry 32-bit apps at the same time (since the OS can access more memory - assuming you have more memory installed of course :-> ).Like I said, 64-bit apps will show up in niche areas first (like the music production apps I mentioned before), then games will start using it more (I know, some are using it now :-> ), then eventually most apps will ship that way (because eventually the OS will only be 64-bit :-> ).Like someone else mentioned, if you have a machine capable of running 64-bit Vista, install it and try it out for a few days (without registering it) to see if it has drivers for all the stuff you want to use, if not, then fall back to the 32-bit version for now and maybe try 64-bit again in a year or so.Tim
