Visual Stutters & Skeleton aircraft.

Recommended Posts

Hi,

 

Forgive me for my lenghty post. But honestly I'm tired of stutters on PMDG.

 

I run the PMDG 738 NGX on a Dell Alienware i7 2820QM (2.3 gh) , 10 GB RAM, Geforce GTX 460M graphics card. I'm encountering regular interval stutters while taxing, takeoff, landing (1000 ft and below) and during turns.

 

It's like ( smooth ...... smooth ....... smooth goes .... on) and then it stops. Same thing while taxing.

While stuttering the frame rate drops to a miserable 5fps.

 

I do not want to overclock the cpu/gpu as it's a laptop and it's never a good option to overclock. In the long run, it's going to mess up the system.

 

I've tried to optimize the fsx.cfg file using ******* Altuve program. But there was no improvement at all.

 

Due to this problem, my sliders are mostly to the left.

 

My setting below. Since I do not have MS-word, I've to type out all settings.

 

Graphics

Target frame rate 20

Global texture resolution - very high

Anti Aliasing - selected

bilinear - selected

lens flare - unselected

directx 10 preview - unselected

adv animations - selected

 

Aircraft

High res 3d virtual cockpit - selected

aircraft casts shadows on ground - selected

aircraft casts shadows on itself - not selected

landing lights illuminate grnd - selected.

 

Scenery

Radius level - small (With a high value, if I walk, I'll reach faster to my dest )

mesh complexity - 50%

mesh res - 38m

texture res - 5m

water effects - none

land detail textures - selected

scenery complexity - very dense

autogen density - sparse

ground scenery shadows - not selected

sp. effects - low

 

Weather

cloud draw dist - 60mi

thermal vis - none

detailed clouds - selected - low

download winds aloft real world weather - selected

 

Traffic

Aircraft traffic density - 85%

gen aviation traffic - 25%

airport vehicle density - med

road vehicles - 22%

ships/ferries/boats - 5%

 

With the above bare minimum settings, I get periodic stutters with PMDG. Please help.

This is a brand new machine and i assume that this a pretty good configuration.

 

Thanx

Sanjay Dhareshwar

Try turning off AI planes, they can be a FPS eater and put FPS to unlimited and use an external limiter.

Try adding the HIGHMEMFIX=1 to your cfg and running your cfg through this handy tool on venetubo.com

Sanjay,

 

Do you use autosave with FSUICP (or something like that) ?

Standard it makes a lot of savings and cause a lot of stutters, but if you save every 10 minutes it isn't that bad.

There is no known issue with the airplane itself that causes stutters - you've got something else causing that.

Speedbird:

When is the last time you did a disk clean? This must be done almost every time before you play. Also the add HIGHMEMFIX=1 to your cfg like phoenixphire said. If you are not sure how to do this there is more info in the forums or you can submit a ticket. Turn off the shadows, turn down the AI, and for at least one flight try to fly with clear sky's. Real World Weather is rough. I fly with it all the time and it took quite a while to get it under control.

Good luck.

Ron

Hello All,

 

To answer your suggestions 1-by-1.

 

1) Ryan you are correct.. and I'm trying to find that "something else" that is causing the stutters. PMDG is brilliant.

2) I did use the Word Not Allowed tweaks from the website. Stutters still present. Skeleton plane still occurs. The tweak has HIGHMEMFIX=1.

3) FSUIPC - I've the inet downloadable version (not the purchased one). I don't save it via fsuipc. I used the " : " option to save flights at reg intervals.

4) I regularly do a disk cleanup and defragment. There is not much on the hard disk so programs run very smooth. It's a new lptp.

6) See above - Shadows are pretty much turned off.

 

I haven't tried flying with reduced AI aircraft's . I could try that.

 

BUT I think this is a software code problem. It's something to do with threading/multi tasking. I say this because when I change the AffinityMask=12, I think I see an improvement in the performance. Don't want to get too excited. Today is Saturday and perfect timing. I'm going to test this further.

 

Thanks,

Sanjay Dhareshwar

If you run FSDT airports then make sure that you have the very latest version of their addon manager. Older versions are known to cause the symptoms that you are describing

Sorry to say but that's not true !!

In Word Not Allowed's guide you have to turn of AI aircraft !!

Very important to read it slow and good!

You have to start with a clean cfg !!

And take your time to follow instructions.

 

Another thing If you are using FSUIPC disable the autosave

 

Good luck

 

Robert
