So frustrated that I thought I'd share as part of the therapy. Got FSX with ORBX and REX OD tried every farking tweak under the sun with limited success as the damn auto gen trees kept farking things up for me (stutters). Seriously have spent the last week trying to get this POS working smoothly. I am running a i5 2500k with a 6970 2GB card ffs its just ridiculous how can I be experiencing stutters?!??! Its an old game by now and I can run ROF with everything on MAX without a prob. Sorry for the rant but what a waste of time more than anything. Microsoft you really did build a #%&*$#, #%&*$#, flight simulator. God help us when FLIGHT comes out.....

Ahhhh that's better.

Danosh

have you tried that ?

FSX.cfg manager/tweaker by Bojote

It helps a lot for better FPS.
Make a backup of yours 1st

I can understand your frustration and the sad thing is that when you do eventually get it running well it doesn't look as good as some of the games that have come along since and play better on lesser specs.

I enjoy FSX but the stock scenery looks pretty rubbish now and is only saved by expensive add-ons.

Having said that it is good for learning plane systems and navs etc.

HAve you OCed your CPU?

For FSX 3,4 GHz is around the minimum.

That said, even with the system below I have stutters at times, but than I have a #%&*$# of addons.

Hate to say it, but MS had a good reason to give the Aces Studio the heave-ho. You found out the hard way.

at Heathrow, with all the traffic + scnenery addon, I have like 5-8 fps....
same thing at Charles de Gaulle....
quite a joke

Did you install SP1 and 2?

FSX is definitely CPU hungry. I didn't get good results until I OC'd my i7 to 4.0 Ghz. Not the most effecient Microsoft programming.......

I have a dual core i7 3.95 GH processor with a Radeon 1gb 5770 graphics card. 8 gb of memory. Runs great. Got REX and the ORBX Northwest Pacific. Favorite place to fly.
Runs smooth. Looks great. Don't have my system all junked up, though. Lean and mean. I use enditall to shut down all running systems. An absolute must. I always know when I've forgotten to run it. I'll go to fly, and I'll be getting little burps and hiccups. Oops. Get out and yeah, forgot to turn off the background programs. You've got to do this. FSX demands all of your computers' attention. It's like Glenn Close in fatal attraction.
I'm able to run the payware, Manhattan New York, scenery, with that helicopter tour with no trouble at all. I had it with my older , single core PC, and it was immposible, of course, without turning the specs down so low, that it wasn't even worth it.
You have to keep your system defragged, too. She's a demanding *itch!

If you can do that, you're a friggin' god, man! Wish I could do that. I live in your shadow, bro'.
