i7-990X and GTX580 low FPS on FSX?!

Nothing wrong with WOAI especially considering its price. Suggest you give it a try. If you're not happy, you can always switch to something else.

Lefu - Maybe the reason your old games ran better on an old sytem is because (A) those games were written for single core and/or (B) the clock speed of your old single-core CPU may have been fairly high.
As for FSX, when Microsoft was developing FSX, their thinking was that processors in the near future would be running at ever higher clock speeds. Instead, CPU development went towards more cores at slower speeds leaving Microsoft with a product release (ie FSX) that wasn't written to efficiently run multiple programming threads on a multi-core CPU. Subsequent service packs improved on this somewhat but FSX is still not very good at using mutiple cores. As for using a six-core CPU to run FSX, having all those cores available is in no way detrimental to the running of FSX. My thinking, though, is that using a six-core CPU for FSX is certainly getting into the area of "over-kill" given FSX does so poorly at utilizing multiple cores and given that an over-clocked 2500K quad-core runs FSX just as well as something like a six-core i9 while costing far, far less.

I am seriously planning in to going to quadcore but now that the new MF (microsoft flight) will eventually be released and, sure, i will be desperatly shopping for it, i am no sure if quadcore will run it well..

Not to worry - a quad core will run it just fine.

I know this is a really old topic but this caught my eye.

My computer specs are even better than yours EmadIV and I only get about 8fps at major airports.... such as Sydney International airport in Australia.

I am currently using only 3 addons..
---> REX Essential
---> ORBX Australia SP4
---> Level-D 767-300ER (Flight 1)
*** I'm currently using Flight Simulator X: Gold Edition***

I am wondering that if I use the utility that is suggested in this thread "http://www.venetubo.com/fsx.html", will all my addons would be affected and everything will go back to default? Or do I have nothing to worry about and it won't affect my addons?

Thanks in advance!

It only touches the FSX.CFG file and modifies it. Your addon will be fine!! It's a good tool. Also follow Noell advice on the other parts as well.

DownlOad a good config file from someone with similar specs

The worst thing that can be done.

I've been using it for a few years and love it. Something about all the realistic livery's flying around with you makes FSX that much better. I have every file that they've put out, even some that have been removed for copyright reasons. For me, it's worth the frame rate hit. And the price can't be beat!

Hello, I have the same problem. I cannot get more than 7fps and I am starting to be a desperate. On pc where I run BF3 on ultra details I cant get FSX to work properly I have i7 950 3,07GHz, Gigabyte UD3R motherboard, 12gb 1600Mhz ddr3, nvidia gtx 670. Ive tried to follow noell guilde, I used nvidia inspector as mentioned and tried to do the same with the cfg file. Not even little improvement, still I load JFK and I have around 7 fps. I did even tried to install some texture conversion (http://mileswebsolutions.com/FSXTextureConversion/) which was supposed to improve my perf but still around 7fps, nothing improved. I have fsx golden with sp1 installed and installed acceleration pack. Yes that 7 fps is on high (not highest) settings. Can you guys advice me what was exactly that you had to set in cfg to increase perf??? Thank you in advance
