FSX low FPS (8-13FPS) on high end PC

[penta_a]

Hello every one
I have a PC with following specifications:
ASUS motherboard Ramp page II extreme
Intel i7 965x @3.2 Ghz
6Gb @1600mbs RAM
2 WD 150Gb each @10000RPM hard disks (windows 7 64bit on one of them and FSX on the other one).
1 Maxtor 300Gb @7400 hard disk (for my data)
ATI Radeon HD 4870 X2 with 2Gb memory.
1200 watts power supply
Thermaltake case (6 cooling fans all over it).
Saitek Flight control

I did follow all instruction for clean installation that are presented in this forum and I still get low FPS and short pauses during flight with professional add on like PMDG products (system OK with default aircrafts, but bad with same aircrafts at busy airports).
I should also mention that FS9 runs with very high FPS till I hit bad weather, it starts giving me 12-18 FPS.
Man I paid a lot for this computer.

Any idea on how can I get the most out of this thing? :-/

Note: I did buy this computer on FEB 2009 and was trying to fine tune it since then using every possible advise from around the WWW including all the advises from this forum before I post this thread, so please do not jump on me asking me to search first

Well, the problem might have several causes.
First of all, the fact that you get

Thank you much for the reply.

1- I have no crossfire, I have one card with dual GPUs.
2- I've been trying drivers starting with 9.1 till 10.1 with no much difference except for one (I can't remember the number that caused low system performance in general).
3- I could not install Video card Catalyst software for some reason (my system just freezes when I start installing it) so I just install the drivers after expanding Catalyst using device manager. so I have no setup for AA, AF except from FSX.
4- Advanced setting in FSX were exactly as posted in tweak thread, then I tried my own tweaking with no luck (I will try to post a screen shot later).

why did you go into tweaking in the first place? unless you know exactly what you're doing, that is not my case when computers are concern, you shouldn't need it. you bought a bigger better computer let it do the job. you should play with the game not the pc. here is my advise, you probably won't like it. go to the fsx settings main page, put back default settings. then go in personnalize, see what the program offer you as original settings and start from that.remember if you add something somewhere the program will take it elsewhere, it's like a balance.i am sure with original sttings it will give you more then 8-13 fps, if it don't clean up a little bit, this mean you have too much stuff running background. i personnaly put more realism in the plane appearence than anything else. i mostly fly in VC so i want it to look real. i dont have any xtreme terrain, mesh,weather or clouds, why should i ? if i want to see clouds i go out and enjoy the view. no pc will ever match the real world. i love flying my plane wherever in the world, i don't care if niagara falls doesn't look like the real one, there not.enjoy your pc. work with it,not against it. preaching finish. see you.

I had the same problem, I can usually run FSX at 20-30 FPS and then I was getting around 8, even with the settings all the way down!
This probably isn't your problem, but it can't hurt to check.
I had the FPS slider set to 10

Trying to benchmark your system with a pmdg airplane (747 in the VC?) will lead to endless frustration!

Your framerates don't sound all that far fetched.

Thanks jlab58,
I did start from scratch (very clean system with all settings at default) and still have this low FPS in busy airports, system OK when I leave airport behind me.
About the terrain and clouds texture, here is the thing, I live in Saudi Arabia (mostly desert with no rain for several years) and it does matter to me to see a good view.
For the background running stuff, I did kill all programs except for the required ones and still same issue.
Thanks for your input.
