8x Sparse grid supersammpling is a way to much, nobody will get more than 12fps with that. Set it to 2xSGSS. (4xSGSS is ok too, but bad weather and HD clouds will killl your fps if you set SGSS to 4x) 

 

 - Change "Nvidia Predefined FXAA usage" to "off"

 

 - anisotropic "filter" and "sample" optimization, both to "off" 

 

 - texture filtering "trilinear optimization" to "off"

 

 - Change maximum pre - rendered fps to 1

 

- NVIDIA Frame rate limiter off

 

 -  vertical sync to 1/2(do this only if you have monitor refresh rate 60Hz, othervise set it to "use 3d application setting"). If you get bad performance, this is becouse monitor refresh rate is not 60Hz 

 

Now start fsx, and in FSX menu - set internal FPS limiter to 30 and select anisotropic filtering. Leave anti aliasing unchecked

 

Now, try and report your fsx performance. Why you guys don't realy read that guides?

With the settings in the pic I posted I get 25-30 FPS in DX10 mode (with bad weather, etc.) These settings are completely different from what I had when using DX9. I appreciate your thoughts though, will give it a try!  ^_^

You didn't mention that :lol:

 

I know DX10 is different, and you can use higher settings. I just don't like idea that DX10 is unfinished in FSX, and for some reason i have stutters. In DX9 with my settings fsx is much smoother

Without any tuning you should still be getting more than 15fps, especially from a core i7.

If you haven't overclocked, I would expect your symptoms.

I disagree with that. I have a i7 2600 not over clocked and a nvidia 550 ti. 6Gb internal ram

Flying with the NGX gives me 30 fps. (that is the maximum framerate I set in Nvidia inspector.)

At the gate of EHAM, very frameconsuming scenery, it gives me 15 to 25 fps.

 

Maybe a very slow hard disk?

Flight simulator is heavily dependant on the CPU.. The higher you clock the processer the faster the performance in the sim. If I reduce my clock on the core I immediately notice the differences.

Yes you're right.

I only wanted to say that you don't always have problems with fps on non overclocked cpu's.

When I overclock I see higher fps, but it is (in my case) not always stable.

(not enough knowledge in over clocking  ^_^ )

CPU I5 and 560 ti stable around 20 frames at airports and 30 fps flying !!

 

And overclocking shortens the life of cpu !!

And that is so frustrating! My computer is so much better, but I never make these FPS.

Martin,

 

It is always difficult.The problem could be anywhere.

Did you tweak your FSX.cfg via this site : http://www.venetubo.com/fsx.html

It helps a lot.

And don't install FS in the C:\programfiles, but in another directory. (C:\FSX or D:\FSX)

 

You can also try to set your sliders in the settings to max. 

It is strange, but if I do so I get higher frame rates.

Only the water setting is at 75%

Traffic at 20% and no boats or ferries. And no bloom effect. If I switch " bloom" to on, my fsx drops to 10/14 fps

 

Succes

DX10 is unfinished because MS fired the team doing FSX. That's why it's still called DX10 preview.

I would have to argue against this one. Overclocking really shortens the CPU life only if you are running it too hot. With normal overclocking and higher (than normal) temps, you will still be able to run the CPU for years without really noticing the reduced lifetime.

Eric,

 

I know and aplied all these hints and tips, believe me. Whatever I try, it is still bad.

Delete your FSX.cfg, reset any profiles you have for FSX in terms of nvidia and see what performance you get then. 

@@joona_ , that's very true, both things About DX10 and overclocking. Anyway, you need to stay in limits of max safe vcore too(procesor specific), not only safe temps. For sandy bridge, 2600k and 2700k, you should not go above 1.45vcore for example. That means 4.8 - 4.9Ghz depending on your cooling(may be higher) and how lucky you are with the chip, and CPU should be just fine for the next 3 years(approximately). You can go higher with Vcore, but then your CPU life shortening will be noticed. Anyway, i didn't planed to use this PC for the next 20 years.

I say this, becouse to many people are talking about shortening CPU life, but there are some question to be asked and facts when you are going to buy new PC for FSX. This is in case you are going to buy PC for FSX, and you want to make your fsx a simulator, not a game. 

 

-  How many years you plan to use new PC?

 - how many years you plan to use your CPU? Keep in mind - there will probably be new, faster, or better overclockers CPU in near future

- most of parts have warranty 3-5 years (well overclocked, stable CPU should last at least 2 - 3 years too)

- you are shortening your CPU life every time you use it 

- you'll never know how is FSX at 4.5 or more GHz if you don't try it

- you'll never know about overclocking and shortening CPU life if you don't try it

 

I know too many people's who will discourage new simmers, but they never tried to overclock, or they have set some too low safe limits. Or they didn't OC in the right way, bad luck etc. You are not going to fully enjoy fsx in this way.  

 

This is how i think about this, sure - no intention of causing offense, just exchange of opinions

 

 

@@Ericd - yes, venetubo helps, but now we have new and better guides for modern hardware. They works a way better than venetubo if you have fast, modern CPU and GPU. 

 

 - Nicks N windows 7 tuning guide + Word Not Allowed's FSX tuning guide are the best combination for me, and many others. Word Not Allowed's guide is for DX9 mode.

 

- if you want to try DX10, you have all info here on AVSIM, in DX10 forum

 

 - and there is AVSIM fsx guide too. 

 

They are all better than venetubo automatic tuning. I'm not saying that venetubo is not good, but we have now better alternatives, which includes bojote's tweaks(creator of venetubo), adapted for new hardware.

 

And you said well about sliders, this is covered in Word Not Allowed's guide, some sliders should be maxed out for better fps. Sliders to the left can mean lower FPS, becouse FSX is a simulator, not a game 

I would have to argue against this one.

 

And then again I would have to argue against this one.

 

Everybody can do this, it is your own choice!!

 

First: why should I overclock when I am happy with the way FSX is running right now?

 

Second: I have two very good friends that really really know everything about computers and work everyday with them!!

 

They say: Never OC if you cant afford to lose your HW. Plain simple!

 

All hardware will eventually fail, overclocking does decrease the lifespan by some largely unknown amount.

 

And there is that part of the silicon lottery!!

 

There is alway's a risk !!!!

Martin,

 

Somewhere on the AVSIM forums (I think it was the DX10 forum, but I can't remember) I came across two other things that people were suggesting.

 

One person said that some graphics card manufacturers ship their cards with the GPU voltage not set at the standard level, but slightly 'underclocked', if you will. This person described a huge improvement when he upped the voltage a little bit (not over clocking though).

 

Second thing: some time ago I came across another person who mentioned that for some reason, some Nvidia GTX cards cannot interact with FSX in a certain way, which causes the cards to be barely used. I don't know how this works or why this would be the case, but I think my card could be one of those models, because when I switched to an ATI card I borrowed from a friend of mine with roughly the same specs as my Nvidia, I did see an increase in FPS.

 

I'm not suggesting that these things will work and these are both things that actually seem highly unlikely to me to be the cause of the problems you're having, because the sim is so CPU-dependant, but it's something I remembered and just wanted to share with you.  ^_^
