Stuttering problem

[Denco 48]

After a while of switching from fsx to Xplane I finally decided to do a flight from a more demanding scenery, I was flying in Slovenia and its neighboring countries for a while now getting used to X plane. I started from London City and wanted to just fly around before I land.

 

The framerate on take off were good, a roundish 26, which in my opinion was great considering the scenery I was in. After takeoff the frames dropped to 20 - 22 so I lowered my objects number to "tons", it was set to "too many" since I had more than 30 fps in my previous flights. Anyway I didn't lowered my objects setting because of fps I lowered it because of horrific stuttering which didn't went away after I decrease my object setting or even after the frames picked up to 30 to 50. I had to move quite a distance from the scenery before the fluidity returned to as it was before.

 

I'll link my settings bellow and I also want to mention that I have Nvidia's threaded optimization turned off since I heard it reduces stuttering. My rig is in my signature.

 

Any advice on this? It wasn't the lack of ram or Vram since ram usage was around 6000MB and Vram usage was 2400MB. I don't believe too high settings were the culprit considering the stuttering continued even after the fps was way above 30.

 

EDIT: 

Addons I use

SkyMaxx Pro ( altough no clouds were present in my flight )

Real Weather Connector

[jcomm 5,890]

I never use cloud detail above 25 %.

 

For the shadows I use only "overlay"

 

For HDR AA - 4x SAA and in NI I set:

 

Triple buffering: OFF

Vertycal Sync: 1/2  refresh Rate

Antialiasing mode: enhance app sett

Antialiasing: 4x MS

AA Transparency: 2x SGSS

 

AF mode: App controlled

Texture filtering negative LOD bias: Clamp

Quality: High Performance

Power management mode: Prefer maximum performance

Multiple display: single display ( I have only 1 monitor )

Threaded Optimization: OFF

Try rebooting windows, that seems to work sometimes. Water reflections is a frame killer for me. World distance is a frame hog too, I have mine set to medium and it looks good enough. Try that and see how that works and you might be able to bring the number objects back up !

The most important "Tweak" for me regarding X-Plane is to turn OFF Threaded Optimization in the nVidia control panel. I think you will find that stuttering will be a thing of the past.  I updated my video drivers a while ago and the stuttering was back until I remembered to do this again.

All the best.

With SkyMaxx Pro having clouds detail set to 50% brings minimal fps loss. At least on my system.

I think I'll play around with the world distance setting. Its a shame though since the sim is running smoothly otherwise.

Threaded optimization is off.

Here's what I'd recommend with that as your current settings:

 

1) Change framerate-lock so it isn't locked to monitor refresh rate. I read on one of the dev blogs that when X-Plane can't manage as many frames as the monitor refresh, it cuts the FPS by a fixed amount of 50%. I get higher FPS without this setting.

 

2) Number of objects and roads is a frame-killer. Scale it way back, and then sneak back up on it gradually to find the optimal setting for your system.

 

3) I'd also recommend reducing anisotropic filter way back. You probably won't notice any real reduction in quality except near the far horizon.

 

4) Reduce cloud puffs to 20-25%. That sounds low, but the actual visual effect isn't greatly diminished at lower settings (this may have less effect with SkyMaxx Pro installed; it's pretty efficient).

1) Didn't know that thx. Don't really have fps issue, compared to fsx, but a gain is a gain nevertheless

EDIT:

 

I'll try decreasing shadow and reflections quality.

I actually have Cloud Puffs set at minimum, around 10%....massive performance increase but no real loss as Skymaxx controls the output.

 

I am no expert, but I got the tip from a few videos and also the Skymaxx forums.

Reduce Number of Cars to Siberia, that is a killer when flying big cities. Also I see you have 8g of ram, why not use Extended DFS?

[sparkie66 81]

Also exclude xplane from active virus scanning. (I fly with av off)

[jcomm 5,890]

Ehehe, even better - use no AV software at all ! Well, I have the default protection that comes built in in Windows 10 ... More than enough, and a scan with Malwarebytes from time to time...

[Denco 48]

I've lowered my "Number of Roads" to default and "Detail level" to Medium and lowered my AA to FXAA only. I now get 35+ fps leaving london city, but the stutters are still present. Just not so severe. I've also added Xplane to my exclusion list in my AA.

 

 

So I've come to conclusion that stutters are not caused by too high settings. Something else must be at play here. Are there official forums for xplane? Maybe I should try their support.

[CarlosF 1,235]

 

 

I now get 35+ fps

 

Denco, assuming you have a 60Hz monitor, have you tried to lock-frames to 1/2 of monitor's refresh?

[Denco 48]

Denco, assuming you have a 60Hz monitor, have you tried to lock-frames to 1/2 of monitor's refresh?

My monitor is 120Hz. I'll try 1/4 and let you know.

 

EDIT: Wait locking my fps by 1/2 and 1/4 will give me fps lock of 30, correct? If so I'll still try it but its not a solution. I prefer higher frame rate.

x-plane.org is probably the most frequented forum. It is not an official forum (there is none), but I guess seen as semi-official by many.
