Hi,

 

I just bought the nvidia GTX680 4GB which i am running on following rig:

 

- i5 3570k OC @ 4.2ghz

- scythe mugen 3

- pwu 550W

- Z77 motherboard

 

I used to have the GTX550ti 1gb which was running FSX between 20-30fps with following add-ons:

 

- FSX gold

- GEX europe

- UTX europe

- REX overdrive

- PMDG 737 NGX 

- Aerosoft Madrid X

 

Being at airport madrid barajas in good weather (day), i am having between 5-10 fps with the GTX680 only.

With the GTX550 ti i was having between 20-30fps everywhere...

 

I am using Word Not Allowed's settings and haven't changed it since i bought the GTX680.

 

Why am i having such low fps?

 

Thank you.

Hiya, well for certain, it's nothing to do with changing the card. You must have made some other changes while installing the newer card. I suggest 1) use driver cleaner to clean the older GPU driver, although probably not necessary, I always do that anyway. 2) Install the DRIVER ONLY during installation of the 680 driver software. Opt for a custom install and untick all the other bollocks that is in addition to the driver. 3) It maybe that you have changed some settings in Nvidia Inspector? Failing that, it will be a question of some further suggestions and advice from others... BTW, IMO Barajas is a vile airport for performance,,,

Dear,

 

thanks for your reply.

I am wondering where to do the changes, in Nvidia Inspector or in the Nvidia control panel where i can make some same changes...

 

I did the expres installation for the cards driver...

 

I have done some other flights in Aerosoft Paris X (Paris CDG) where the FPS i already better between 11-20 fps.

 

Is it possible that the FPS is dropping because the resolution is higher and asking more of the CPU even though the GPU is much more performing?

Hi,  for inspector settings check this post out elsewhere on the forum:

 

http://forum.avsim.net/topic/324786-nvidia-configuration-guide-inspector-2xxxx-drivers-version-20-explanations-of-all-settings/page-20?hl=%2Binspector+%2Bsettings#entry2789973

 

If you did the express installation then I would suggest you now uninstall the GPU, do a driver sweep/clean and then reinstall the driver using the custom method, only installing the actual driver and nothing else.

 

If you have Nvidia inspector installed, then never open the default Nvidia control panel, as soon as you do and make any changes it will effectively make your Inspector settings obsolete until which time you go back and initialise them.

 

You ask if frames are dropping because of the additional resolution? I'm afraid I'm at a loss here... are you saying you have increased the resolution? If so how? Have you changed monitors to a higher resolution? You don't increase the resolution by simply upgrading your GPU. Where you will get a hit, is if prior to installing your 680 you were using the default Nvidia control panel and then now you are using higher anti aliasing and filtering settings through using Inspector.

 

From where I sit, you have made some radical changes while changing your card and I suggest you figure out what those changes have been.

 

BTW, Aerosoft's CDG is one of the heaviest performing airport you can fly from!

Hi,

 

I will try uninstalling it. Should i just uninstall the driver or the full GPU?

 

Initially i hadn't changed anything about the control panel, nvidia inspector. I haven't change screen resolution neither.

BUT, in fsx you can change the screen resolution higher. I have done that, as i thought i have to increase it to get better visual graphics.

 

Will i get higher graphic resolution just by using the GTX680 without doing any change? If not, what is the purpose of having a GTX680?

 

I always used to use Nvidia inspector...

 

It's strange that FPS is higher at CDG than Barajas... no?

Hmmm ?

 

Ok...

 

Should i just uninstall the driver or the full GPU?

To uninstall I don't mean take the GPU out of the PC! You uninstall through the add/remove programmes in the CP of Windows. Then run a driver cleaner, plenty on the net, some free. Then relinstall just the driver after having rebooted the computer.

OK, FSX resolution in the settings page should be set at whatever your default monitor resolution is running at. The most common res is 1920x1050 for a LCD/TV or if a PC monitor, 1920x1200. Check it out via the display settings of your monitor in the Windows control panel.

Simply by changing a graphics card does not alter the resolution of the display, although you can do, but you should be running at the monitor's native suggested display. The monitor is provided data from the CPU which is displayed by the graphics card. How well the data is displayed is determined by the quality of the graphics card. The better a card can deal with antialiasing (horrible jaggy bits) plus texture filtering, and other things that help to display an image, then the better quality picture you'll be looking at. The easier it can fulfill these requirements then the easier it is in other areas of the whole data processing system. Changing the GPU for FSX, will have a very marginal affect on frames, if any, but upgrading the GPU can improve the things I have already mentioned. How much of an improvement is determined by the type of GPU you will be using.

 

I always used to use Nvidia inspector

That's good, don't touch the default Nvidia control panel. In that case, run the inspector settings with some of the samples shown in the post I gave a link to.

 

It's strange that FPS is higher at CDG than Barajas... no?

Different airports and sceneries will give completely different performance and this is determined by many, many aspects. To name just a few, size of airport, amount of autogen, amount of airport vehicles, amount of AI, and of course the biggest factor, how well the airport was or was not designed.

Also check your FSX.cfg for left over display devices. Only the new GTX 680 should be listed.

Hi,

 

Indeed, the old GTX550ti was still showing up there. Should i just remove the lines underneath that?

 

[DISPLAY.Device.NVIDIA GeForce GTX 550 Ti.0]

Mode=1024x768x32

Anisotropic=1

 

[DISPLAY.Device.NVIDIA GeForce GTX 550 Ti.1]

Mode=1024x768x32

Anisotropic=1

 

[DISPLAY.Device.NVIDIA GeForce GTX 680.0]

Mode=1680x1050x32

Hi all,

 

I have created a new fsx.cfg file. Now i only have one display line with the GTX680.

 

I cleaned the drivers and reinstalled the GTX680 driver. Now the driver is 320.49.

I have checked the nvidia inspector settings without changing the control panel settings.

 

But i am still not pleased with the results i see.

Apparently Madrid X is a FPS killer.

At Heathrow X and Paris CDG X with PMDG 737 i get better FPS: between 10-20 fps...

 

Once i the sky with clouds (REX) it is between 18-24 fps.

 

Should i expect better FPS? Should i change other Nvidia inspector settings?

 

Thank you

What model PSU are you running?

 

Minimum recommended for the GTX680 is a 550W so you should be ok ona good PSU, but if your PSU is not up to scratch even though it states it's 550W it may not be delivering enough juice. Just a thought.

 

Otherwise perhaps it's just the scenery you're using pulling down your FPS.

 

What sort of FPS do you get for example at a default location like the default flight or at Seattle?

Dear,

 

My PSU is only 500W, but i have no crashes in the system. I guess the PC would shut down if the GPU is pulling out all the juice out of the PSU.

 

If i fly a default Cesna in Mega Airsoft Brussels X i get 30fps easily.

So i would most probably get the same in a default scenary (fps is locked a 30fps).

 

But in combination with the PMDG the FPS is going down...

At Heathrow X and Paris CDG X with PMDG 737 i get better FPS: between 10-20 fps...

 

Fullscreen or windowed? Have you tried changing just to see results? healthrow I will get 20fps with locked at 30 so I wouldnt be to concerned specially with any amount of AI.

I always play fullscreen in VC.

I have 75% of Ultimate Traffic AI and get between 10-20 fps...

 

If i use 3 screens using nvidia surround, would the FPS drop even more?

This topic, as so many framerate topics get, is so subjective. There are dozens of reasons you may not be happy with your frames. The first thing that needs to be said, is that framerate, while a good yardstick, should not be deemed as the be all and end all of a successful FSX install. If you are getting smooth flying, without stutters, blurries and so forth, then you are almost where you need to be with having a stable and enjoyable FSX experience. The other thing that is coming out of this thread is you are flying at some of the most framerate/intensive airports available! CDG, Barajas and LEBL are among the worst performing airports I've had the displeasure of owning! There are loads of other things that could affect your performance hat has not been discussed. Simply by running AI at a high setting can affect performance immensely, as so can a combination of other things. Rendi made a good point, running either full screen or windowed mode can also affect frames. FWIW, here are some settings that I use that could help:

 

Aircraft shadows on the ground. Unticked

Aircraft shadows on itself (or something similar). Unticked

Bloom. Unticked

Ground shadows. Unticked

Run all textures at 1024 res

Disable all airport vehicles

AI ferries and boats. 8%

AI aircraft 10% if default, no more than 30% if third party addon such as MTX

If running with a frame intensive aircraft such as the NGX then autogen set at normal

For GA flying in urban areas set autogen to dense, for bush flying autogen to very dense

For water settings run (I think away from rig) low x2 or with Bufferpools tweak maybe High x 2

I have just noticed you're running your AI at 75% well, IMO that is waaaay too high, knock it back to 35% and see what you'll gain. As I say, these are my settings and I run a pretty fast rig. I hope you find them useful, just a few options. I'm away from my rig at the moment but all I can say is that it is so very easy to expect too much from FSX. By being a little more conservative with your expectations you may become a little happier. Anyway, see how you get on and report back to us all...

 

BTW, you say.... But in combination with the PMDG the FPS is going down... Of course they are... Running a quality addon such as the NGX, which has been developed to such a high degree of quality, will always be more intensive than a default aircraft.

hi

 

Thanks again for your reply. I used to runthe gtx550ti considering lot of the settings your mentioning. For this i followed Word Not Allowed's tweak guide.

 

I will try out the ones i haven't tries before.

 

I know which are the FPS killing add-ons etc... Thats not the point for me.

I am just astonished that i almost don't see any differences between the 550ti and the 680.

I even feel that some sceneries are running worse.

 

I am certainly not expecting miracles here, but just some improvement compared to the previous setup. Don't you agree?
