FS9 Stutters with Quad core: really?

Featured Replies

That's not an unreasonable number of processes. I regularly run with around 60-80. You need to enable the "CPU Time" column to see which are consuming the processor, and you need to see what's going on at those 60 second intervals. That's likely the cause of your problem.

 

Cheers!

    If the stutter happens at exact 60 second intervals, it is not FS9, but some other process on your computer that is running at regular intervals and either momentarily hogging the CPU, or causing a di

  • As mentioned above -- multi-core CPUs weren't really a thing when FS9 (or even, to an extent, FSX) was released. I suspect MS developed the code based on what had been true up to that point -- the ass

Your processes seem fine as mentioned above and if you uncheck "Show processes from all users" you will see less as the duplicates won't show. You do first want to make certain nothing on your system outside of FS is causing the stutters. Quickly scanning your process list, things like O&O and whatever the malware thing is I would disable these totally and then check FS. It's these kinds of system tools that can often create the biggest headaches.

Edit: Just looked again and also found the advanced system care process. All this type of stuff disable and then try FS.

I it's been a long time.

Sorry about that.

 

There are a good improvement.

After installing the CFF Explorer

I fire up FS9

Infinity masks to "0"

Priority to "High"

O & O defrag

 

It's not perfect, maybe I need to work on FS9. Cfg

What is the top resolution of your monitor/tv.  FS should be the same.

 

NI profile, try just 8 instead of 8S.

 

Can you post your cfg so we can take a look.

Finely I get ride of the stutters thanks to config in FS9config.

Especially :

+ TEXTURE_BANDWIDTH_MULT=210

+ TERRAIN_DEFAULT_RADIUS=3.700000
+ TERRAIN_EXTENDED_RADIUS=3.500000

+ //TEXTURE_MAX_LOAD=1024

 

and it default put it back to

+ TEXTURE_MAX_LOAD=512

 

 

and thanks to this topic

 

the result is quite good, but not top max.
maybe because of the CPU, I don't know.

 

 

 

i7 would be better, frankly I don't know

What is the top resolution of your monitor/tv.  FS should be the same.

 

NI profile, try just 8 instead of 8S.

 

Can you post your cfg so we can take a look.

Dear RichD,

 

What do you mean by :

"NI profile, try just 8 instead of 8S"

 

Thanks

Sorry for the delay, setting up a new rig :fool:

 

In Nvidia Inspector, Antialiasing Setting = 8s. Try 8

 

Just noticed in your CFG the following;

 

//
//TEXTURE_MAX_LOAD=1024

 

Should be;

 

IMAGE_SMOOTHING=1
TEXTURE_MAX_LOAD=1024

Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz 3.60GHz. RAM 32 GB 1 500GB SSD and 1 2TB HDD NVIDIA RTX2080Ti 11GB WATER COOLED

One of the most common reasons for "regular" stutters is addware in the background trying to log on.

Download a free copy of autoruns.exe. That will show you everything that starts up and will allow you to block stuff that is unnecessary or unwanted. For a while my sim used to pause to desktop until I found some addware that was the culprit and stopped it.

I did every thing I could in msconfig

Let's see how does autoruns help us.

Hold on, you have got things a little mixed up in your cfg.

Here are the important parts of mine and it works real well.

 

[GRAPHICS]

TEXTURE_MAX_LOAD=1024 // this sets maximum texture size to load. 1024x1024 is max what fs9 can handle and should always be used. Note! Only in the [graphics] section!

 

[DISPLAY]
UPPER_FRAMERATE_LIMIT=62 // this is because it gives a little margin when I use Vsync @ 60hz (fps)
TEXTURE_BANDWIDTH_MULT=120
TextureMaxLoad=8 // Note, this is NOT the same as the texture_max_load in the [graphics] section
 
[TERRAIN]
TERRAIN_ERROR_FACTOR=100.000000
TERRAIN_MIN_DEM_AREA=100.000000
TERRAIN_MAX_DEM_AREA=1000.000000 // Don't know what this does, but it's possible to use high values
TERRAIN_MAX_VERTEX_LEVEL=21 // Because I use NextMAP Europe Mesh which has 19m resolution
TERRAIN_TEXTURE_SIZE_EXP=8
TERRAIN_AUTOGEN_DENSITY=5
TERRAIN_USE_GRADIENT_MAP=1
TERRAIN_EXTENDED_TEXTURES=1
TERRAIN_DEFAULT_RADIUS=3.9 // Keep below 4.0 to avoid tearing in the scenery mesh
TERRAIN_EXTENDED_RADIUS=3.9 // Keep below 4.0 to avoid tearing in the scenery mesh
TERRAIN_EXTENDED_LEVELS=1
 

If you're using NI, try using Nvidia Control Panel instead. N Inpector seemsed to give me stutters for some reason. CP gives me smoother performance.

 

Just an option...

NI gives you more antialising modes to choose from than CP does. That's the only difference.

 

It's of course the AA mode you choose that determines if you're gonna get stutters or not.

 

Using NI is better because it also has a GPU monitor so you can see your GPU load.

If it maxes out at 100% when you are V-Synced, then you need to lower your AA setting, otherwise you'll get stutter.

Test in the heaviest weather to see how your gfx card handles it. Then start testing modes.

 

I've got a GTX970 and a tip if you guys have a similar or better card, is to use 16xS for normal AA and Supersampling 4x for transparency AA.

It handles full overcast and thunderstorm weather without a a sweat (on my 1920x1200 monitor), and the image quality is sharp and vibrant, almost without shimmer.

16xS is probably too much for the OP's multi-monitor system though... Maybe try Multisampling 4x.

I've found regardless of settings, like others, NI provides the stutters whether GPU usage is low or not. Since switching to CP, stutters gone. Strange but true.

 

I use the same basic mode in both except no SGSSAA which CP doesn't have.

As i said, the AA mode you choose is what matters. You said you use a "basic mode". You need to be more precise than that.

Tell me your NI settings and I'll help.

Basic mode like 4 x AA and 4 x SGSSAA. Gpu was never maxed out.

 

Ditching NI removed the stutters. Simple as that.
