You wasted your money!! Go back to FS9

What drivers are you using? The newest ones (185.xx) suck...the version 182 drivers are much better for FS

BobI am rapidly coming to the same conclusion as you: The 185.xx drivers are not doing well in FS, at least with my 8800GTX.What in particular did you find wrong with the 185's?

The 185.xx drivers are not doing well in FS

No problems here, I

I did a reinstall of FSX and some testing along the way using 182.0x drivers with the 285GTX 1st run was the same sh#t.FSX SP1 same sh#t, FSX SP2 same as before sh#t. Connected a 2nd PSU just to run the 285GTX and was the same.Run 1 7800GTX now getting lot better FPS more than the 285GTX was doing, 7800GTX x2 Sli only a small change in FPS.I could up all sliders in the game to max and get more out of the 7800GTX cards that i could would 1 285GTX.So now its a clean install of vista 64 to see if i can get my FPS from the 285GTX but i dont like my luck

VillanThis is counter-intuitive. Like one of the other posters, I got a good boost from going from an 8800 Ultra to a GTX 285. And I only bought the 8800 to begin with because everyone at the time thought it was the best card for FSX.When I read your first post in this thread, my initial hunch was that you forgot to delete the FSX.CFG file when you upgraded your card, which might have prevented FSX from adapting properly to the upgrade. However, I see that you have since reinstalled FSX, which SHOULD have given you a clean FSX.CFG file so that shouldn't be the problem. You might just want to check, though, by deleting it and letting FSX re-build. But otherwise, it sounds as if your registry has got into a muddle (which your fresh OS install should sort out) or there is something wrong with your GTX 285. Different driver versions - assuming there's no underlying corruption in the OS - shouldn't make THAT much difference.Also - and I'm sure you know this so forgive me - your images showing a very high FPS are taken in areas where the load on FSX is extremely low: pretty much just the landscape textures in a completely clear sky. Your new GPU will help you much more when you've got lots of different cloud layers, mixed visibility and you're approaching a major airport hub near a socking great city with lots of polygons.Tim

Mace,The 185s introduced massive stutters for alot of FSX users. The 182.50 drivers are solid and smooth. I have a suspicion that it can be a problem between the drivers and specific hardware and how well they play together. If I use the 185s' in DX9, and run FSX, my DPC Latency goes through the roof and there is no amount of tweaking that I can do to rein it in. The drivers behave differently in DX10 and the problem is not exhibited. I however am not going to give up the visual quality of FSX run in DX9 mode.

FS9 does not leverage the GPU either and grafix are hideous, oh and enjoy the popping tiles all the time.

I have done a clean installed of vista 64 and installed FSX with SP2 using 182.05 drivers. I have got it to look a bit better with no add on at this time but still have some spikes and have the scenery moving left and right or up and down the screen when the jet im using will stay in the same place on the screen. Sometimes with taking off the lines on the runway when looking from outside the jet are moving like a stop start or really poor frames. I have overclocked my CPU to 4Ghz and the 285GTX to 700Mgz and underclocked as well trying to fix the problems.

Now with a clean install try this:

1. Remove all tweaks in your fsx.cfg file.
2. Limit FPS in FSX to 25 fps
3. Load a flight and go to an outside view and pan around your aircraft.

Do you still get the spikes after this when you continue that flight?

I never got back to doing tweaks as i wanted to get it running almost stock before adding more to the sim.After setting FPS to 26 i no longer got shutters and spikes so thanks for that as it was driving me nuts.I have the sim almost maxed out on all settings using some heavy scenery going as well and only drop down to about 12fps without screen shutter

I am having some similar issues.... Here's my set-up:Core i7-920 (not clocked... yet)6GB Corsair DDR3 RAMAsus P6T V22 WD VelociraptorsnVidia 9800 GTXVista Home Premium x64I have the OS on one HD and FS-X on another. I started out using the 185.85 drivers, no tweaks, no nHancer, no FS add-ons.... with the default aircraft I was getting great performance; no stuttering, smooth graphics, high frame rates. I was thrilled!!!Then I installed nHancer 2.51 and followed all of NickN's tweaks (please don't interpret this as a swipe against Nick as he has been nothing but helpful and informative in my experience). My performance did degrade some.... some stuttering, slightly lower frame rates..... but I had turned up some of the sliders and the performance was "liveable"...Then I installed PMDG's 747-X... :( the world as I knew it ended.... Corrupted graphics, black screen, missing textures, etc... There is a very large message thread devoted to that topic. I am in the process of completely re-installing everything from scratch (not the OS) and starting over (assuming my wife doesn't call her lawyer first).I have come to the sad/harsh conclusion after many hours and alot of $$ that we are beating our mutual heads against the wall. The fact is (to paraphrase NickN) that FS-X was designed with old graphics technology and tested on Windows XP... If you layer in Vista x64 (and all the associated Vista issues), nVidia drivers which are designed to deal with modern graphics (pixel shading, games like Crysis) and top it off with complex resource-heavy add-ons like PMDG aircraft, we are rolling the proverbial dice.... These forums are filled with a spectrum of results: folks with no problems who report wonderful performance, guys holding their head in their hands and sobbing, and everything in between.The outlook for the future is even more bleak. With the demise of ACES and MS appearing to have no future development plans for FS, the hardware world will continue to march forward with technology designed for much more advanced graphics and Windows 7 will be the defacto OS on the block, adding further confusion and mystery to our little world.Phil R.Wow, sorry for waxing philosophic..... I guess I need to get out of the house and hit the beach for a little R&R (weather permitting in NY).....
