Good fps but bad stutters mainly when taxiing

Recommended Posts

Hello everyone,

 

I know that this subject has been adresses hundreds of times but i still i cant find any way to eliminate stutters in fsx even if i have great fps. My fps are locked internally at 30 and i have 1/2 refresh rate vsync with Nvidia inspector. I tried a few teaks to get ridd of those nasty stutters but nothing really worked for me. I also know that each case is different, thats why i am linking here my specs and my cfg. If any body have an idea about how to eliminate or decrease the stutters i would be eternally greatful.

Have a nice day ! :lol:

A quick look ... personally I would suggest your graphics card is choking with your setting of texture max 4096... , you could try to reducing this to 1024 or 2048 - as well,  your OC may be too much for the card so you could adjust your OC from 4.4 down to something your graphics card can handle via the Bus

I can see a number of things in your CFG that may be causing this.

 

Try deleting your FSX.CFG file (you can back up first if you wish) and FSX will create a new one when you load FSX.

 

Then close FSX, edit your FSX.CFG to put back ONLY the following:

 

[GRAPHICS]
HIGHMEMFIX=1

 

WideViewAspect=True

 

TEXTURE_MAX_LOAD=1024  (should be there, and you can move to 2048 or back to 4096 later after testing).

 

[JOBSCHEDULER]
AffinityMask=14 - This is okay, but you might first try not using an Affinity Mask setting.  Let me know if you Stream your flights and we can work on the best settings for you - IF you actually need to use Affinity Mask (again, you may not).

I recently had a similar problem which i was able to solve by finding out the right

balance between Affinity Mask and Bufferpools/reject threshold setting.

Below is how i set mine and it is working very well.

 

Give it a try!

Thank you all for you very quick answers I'll try the few things you suggested. Hope something will work for me :)

 I tried just that but it seems that my fsx suffers from even more stutters after it :(

Is it possible that I have to entirely reinstall FSX and all my addons for the stutters to be gone ?

Lateros,

 

Here is what I done.

 

1-Start FSX

2-Open Task Manager

3-Open Processes

4-Find fsx.exe*32 file and right clik on it

5- File Location page will open

6- Find "Set Affinity" click on

7- Which processors are allowed to run "fsx.exe*32" will open

8-Check only "All Processors"

9- 0-11 CPU will have the check marks

 

Close it and go fly.

 

THis is worked for me. It may not  work for you,so be carefull do at your own risk.

Did you noticed  what % Load you have in CPU "0" in Task Manager?

 Its around 20 to 30%. The three others are going up to 100%

Someone told me that wanting to achieve LOD radius=5.5 and bufferpools with a GTX600 is madness. Do you think i may have to get at least an other bufferpools setting for my GPU ?

in FSX set frame limiter to unlimited and set 30 fps limit in NVI plus vert. sync. - 1/2 refresh rate ( i assume that ur monitor or tv is refreshing with 60Hz )

Can you 100% confirm that you renamed your fsx,cfg and rebuilt a new one? If its still stuttering after that then probably a reinstall ...I feel your pain I just did it with a full reinstall of win7as well and that made an unbelievable difference as you would expect

As I suggested earlier, it cannot harm your system if you drop your overclock from 4.4  and try 4.2 or 4.0. Your 660 Card could be  choking at the bus with your high settings in the FSX.CFG file and that overclock. While others may disagree, have a look at the video Cards section of Nicks Bible - It doesn't mention your card specifically, but you can glean a lot from the article.. you can find the bible here;

I write a little how to now, but if you want it to be successful, you absolutely need to STICK to this how-to. Afterwards, if you are not happy with the one or the other setting, you can still change it, but DO NOT try to change some settings while going through my list. Here we go:

 

Delete your FSX.cfg and let FSX build a new one. Open your Sim, set your resolution correctly, be sure that you use 32bit for colours and make sure that all those .dlls are accepted again. Then you exit FSX without doing anything further.

Then, you open the config file with a text editor, and you check if

HIGHMEMFIX=1

is correctly written in the section [GRAPHICS]

Now, you can modify your FFTF value. For this, you add in the section [Main]:

FIBER_FRAME_TIME_FRACTION=0.22

I would start with 0.22, the standard value is 0.33, lower values increase generally your FPS with the risk of blurries... I would never go higher than the standard value of 0.33...

Now, you fire up FSX and you go through the settings. First, set the internal FPS limiter to 33.

Then, I would select in the graphics section:
- Resolution as you want, 32bit.
- trilinear filtering, antialiasing off (we use nVidia Inspector for this later on)
- global texture resolution to max
- no DX10
- lensflare on
- lightbloom off
- advanced animations on

in the aircraft section:
- 3D panel or 2D panel as you want
- no transparency
- no tooltips
- high-resolution 3-D cockpit on
- aircraft casts shadows on the ground off (unless you use only fsx-native AI models or no AI at all)
- aircraft casts shadows on itself off
- aircraft landing-lights illuminate ground on

in the scenery section:
- level of detail radius: large
- mesh complexity: 100
- mesh resolution: 10m
- texture resolution: 7cm
- water effects: low, 2.x
- land detail textures on
- scenery complexity: very dense
- autogen density: normal
- ground scenery shadows: off
- special effects detail: high

in the weather section:
use the pulldown to select "ultra high", then:
- thermal visualization: none
- select detailed clouds and move the slider to "high"
- simulation settings as you wish (depends on whether you use an external weather tool or not)

in the traffic section:
- airline traffic density: as low as possible, depends on your AI traffic tool, if you use none, I would recommend nothing higher than 20%

- general aviation as above...
- airport vehicle density: as low as possible, I have it off, as I mostly fly to and from AES supported airports. For GSX, check their manual.
- aircraft labels at will
- road vehicles: max 5%
- ships and ferries: max 10%
- leisure boats: max 10%

Thats for a beginning. If you encounter low FPS, start reducing autogen and AI traffic first without touching any other settings. Autogen, AI traffic and those vehicles (airport, ships, cars) are FPS killers, you can reduce those settings always a notch without loosing to much image quality and immersion.

 

Now we can fire up nVidia Inspector. Open your FSX profile and change the settings as followed:

 

- Antialiasing behaviour flags: none
- Antialiasing Mode: override any application setting
- Antialiasing Setting: 8xS
- Anisotropic filtering mode: User-defined/Off
- Anisotropic filtering setting: 16x
- Texture filtering - negative LOD BIAS: clamp
- Texture filtering - Quality: Quality
- Multi-Display/mixed-GPU acceleration: single display performance mode
- Power managment mode: prefer maximum performance

and, most importantly:
- Vertical Sync Tear control: standard
- Vertical Sync: 1/2 refresh rate


And that's it. This should give you without touching your 4.4GHz OC on your CPU a nicely fluent and smooth experience with FSX.

 

Just keep in mind (again): if you do not stick to above "manual", nobody can help you. If you think you know it better and instantly put LOD_RADIUS=5.5, textures to 4096 and stuff like that, no one here ore somewhere else (simforums...) will be able to help you.

Hey, I happen to have the same setup as you.

I5 4670k, overclocked to 4.4, 8Gb Ram, GTX 660, Win 7 64 bit. Same.

 

I see from your CFG that you are running DirectX 9.

On my system with a clean install and simply the HighMem fix, FSX + Accel, I get great frame rates and no stutters even with Anti Aliasing turned on.

Adding in WOAI aircraft at 60% and a single payware or freeware airport - still no stutters.

 

I have since switched to DX10, but by system ran very smooth with DX9.

 

What else do you have installed?

 

Your video card should not choke this game unless you are running full AA and have a crapload of Cumulus clouds and a thunderstorm going on.
