I really liked Win7 RC compared to Vista (In general, not in regards to FSX). But, I went back to Vista 64 as I knew it was stable. For the record, I didn't see any performance difference in 7 compared to Vista for FSX. It will be interesting to see what the RTM looks like...BTW, Vista Nvidia drivers will work fine in 7. The 185 drivers are crap in my opinion.

Here's my personal experience with FSX and Win7 Ultimate.I've just completed a series of tests between Win7Ult v7137 and Win x64.Here's what I did: 737 is sitting at end of 14R at KORD. Time is 12:00 midday.No clouds. No ai.Autogen DenseScen. Complexity V. DenseWater Low 2x. Mesh at max.Textures 1m. Aircraft details Xtra High.Default scenery. No UTHardware: C2D 8500 at 4.1ghz, Ram 4gig 1066, mb Asus P5q pro, GPU GTX285-1gig ramDrivers: 185.85 (not using Nvidia CP) Nhancer 2.51Setting AA combined 4Xs, AF 16x, Vsync offPC in triple boot XP x86, XP x64 and Win7Ult X64So, what are we comparing here? FSX SP2 under x64 XP and Win7Ult x64 on the same PCBoth defragged with O&O space/name (per Nick's procedure)Here are my results All tests have been repeated 3 times and PC has been rebooted also.No further comment,edit: Both OS were tested for smoothness: using the P51 and flying at 200ft/300mph in Chicago area. No difference, both were crips and smooth.Pierre

Additional info about adding Scenery in FSX with Win7.1. Select the folder of the scenery (as usual);2. The result is that the folder is opened and you can see the <scenery> & <texture> folder. That is not normal.3. But wait, there's a way : RIGHT click in that scenery folder and lo and behold you<re brought back in the FSX scenery window (which should have been done after step 1)4. Click OK and the scenery is loaded.I am just passing that neat trick here. I found that somewhere on the web. Very clever (or very lucky)Pierre

you're right, no comment other than the test just by the description is flawed.. very flawed

Explain please.

Just to name a few?I

Nick calm down. Relax a bit, will you?The point of having no traffic or weather is to make a true comparison between two FSX situations in two different OS's. It is a STATIC comparison. <period>No more, no less.I did those tests for myself, sure they aren't ISO9001 but they tell me that I will likely use Win7 in the future. I say likely because I don't go for hype either. I still need to do further testing, and that I can do It has been part of my job for the past 15 years. That chart up there is for real. People will decide for themselves,I will stop here. Amen to that.Cheer up man, take a breakPierre

whos not calm?you asked LOL!In a nutshell, your test methodology does not reflect a realistic performance evaluation of a simulation and the title in question. I do not have to get excited to know thatthe initial post 'suggested' the way it was presented you were getting some kind of large perf increase when that is not in any way shape or form the case. Since you asked I am going to be quite frank.. Microsoft was smart this round. Instead of making people buy the OS they released a stable version of a past OS with fixes and changes.,. never underestimate the power of the

You are in your right to be sceptical Nick, and I have my reservations about Win 7 - especially the fact that it should be a free upgrade fixing the flawed Vista rather than a new OS, but: I see +30% fps easily in most situations, with traffic, with weather, etc. Flawed methodology or not, is is faster and smoother.

what is your spec?What is the graphics driver your are using if nivdia?

I dont have to be sceptical.. I have them all sitting right here and have been testing on them allfigure out what was wrong wth your last install then you will figure out why the increase, plain and simple

I have tried FSX SP2 on Windows 7 build 7100. I notice that everything runs smoother until i turn on AI which frames decrease a lot. Is there a problem inside FSX that reduces frames a whole lot when AI is enabled?

Try calculating the position of over 100 planes in one area by yourself and giving vectors to all of them and controlling them so they arrive at their destination and see if it slows you down... FSX has always been slowed down by AI, no matter what OS.

ISTM that Win 7 is aimed at the business Win XP installed base. Doesn't really offer anything for a Vista user. I guess through repackaging they are changing Vista biz into Win 7 pro (incl media stuff), which it should have been all along, considering the uptake of Vista Ultimate apparently hasn't been great.scott s..

ie., there certianly no improvement in performance. and the graphics are a lot worse compared to Vista, this may be due to the Nivdia driver.

the new nvidia drivers are bugged. I get very bad performance with 185.85 on vista OR Win7. Details on the nvidia forums :)

ah, I was wondering how long it would take for the condescending tone to creep back into your posts.I don't have to figure it out, my last Vista installation was good and solid. My new Win 7 is faster.
