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.

 

It's not official in the sense of being run by Laminar, but this is the largest X-Plane forum:

Look for the "Technical Support - Cubby's Corner" sub-forum. Note: unless they've changed it recently, I think you have to post a few times to an existing thread before you can start a new thread. The moderation over there can be a bit grumpy at times, but it's a generally helpful place to ask for tech support.

I prefer higher frame rate.

 

This is from Laminar:

 

Frame Rate Locking

The frame rate lock to monitor drop-down box allows you to steady the simulator’s frame rate by not allowing the frame rate to exceed a certain value. If X-Plane generally runs as a high frame rate on your computer, but does not do so smoothly and consistently, you can lock the frame rate to some ratio of your monitor’s refresh rate to keep the frame rate steady.

 

Ideally, constant 60fms would be perfect, but realistically unless you have the newest and greatest hardware, this will be hard to achieve unless you go with minimal rendering settings.

 

Try at locking at 30, just don lock from within the sim, use driver control panel or Nvidia Inspector.

Sadly locking my frames did not work. The stutters were still there, same as before :(

Have you used GPU-Z to check how much VRAM is actually being used? The indication you get from XP is just the size of loaded textures and should not be relied upon. I find you have to adjust things until your usage is below what's on your card or you get stutters. Worth a shot, worked for me though it looks from your screenie like it's unlikely to be the problem tbh. You really should reduce your cloud puffs to 10% though.

The recommended procedure to isolate an issue like that, would be to lower ALL settings to the minimum, while at the same time disabling ALL add-ons. Then you can check if you still have stutters, and then you can increase the settings one by one to identify which one is generating stutters.

Max VRAM usage was 2400MB. Don't worry about the puff's I'll lower them the flight didn't had any clouds so I didn't even bother

Looks like I'll have to take this road.

Also, if I may suggest, I see your I7 OC to 4.5, some systems become somewhat unstable when reaching highest possible OC up to the point that it is no longer reliable but not unstable enough to crash the sim. As a last resort try bringing down your OC a notch, you can always bring it back up if did not make any difference.

 

Just a thought.

It depends on what you call stuttering, just to make sure, do you mean it runs at a reasonable framerate (for X-Plane, that is, so 20-30 or better, on a very good graphics card) but every now and then it stops for 100 ms to several seconds, then goes on, freezes again, and so on?

 

I could solve those problems on other programs like DCS or P3D by moving to an SSD, but this is not enough for X-Plane, apparently the problem is deeper with this one. And you are also using an SSD, so you should be safe from disk fragmentation (maybe not cache read-ahead optimizations, but I don't believe this would have much to do here anyway).

 

The greatest contribution to a smoother experience I had so far is disabling the "Threaded optimization" in the nVidia Control Panel. But you mentioned straight away that you had this off.

 

Traffic off also helps a little bit. And you could try this, to reduce the impact of auto-gen and rule that out:

To be honest, I haven't tried it yet. Perhaps an intermediate step would be to test in which area those stutterings are happening, and are at their worst - near cities, does that also happen in plain country, above the sea... ?

 

Regarding other suggestions, I wouldn't turn off vsync in X-Plane, as it gives very ugly frame shearing. The best is to enable triple buffering in nVidia Control Panel, and sync to monitor in X-Plane. This won't affect significantly the framerate and disconnect the rendering engine from the synchronization.

 

Good luck!

 

I hope they'll improve the parallelism in 10.50. And the loading time, for now that's what is discouraging me from experimenting more, having to wait for minutes between each change of settings is painful.

@Redglyph:

 

1) I am using, since yesterday the booster script, and it does bring some additional smoothness to my X-plane 10 / Aerowinx PSX combination.

 

2) You mentioned using Vsync. I am using 1/2 Refresh rate in Nvidia Inspector, but didn't enable triple buffering. Will give it a try, as well as forcing sync to monitor in X-Plane rendering options, which I believe I did not enable...

After a week of testing I haven't experienced stutters, for now, in other scenery's that I've flown, apart when flying around London.

Can you let us know what you did to help with the stutters?

In Europe, you can encounter massive scenery loads on the system.  As mentioned above, get a copy of GPU-Z and monitor the GPU VRAM load under those conditions.

 

Also, you do not need the nVidia Inspector.  All the controls you need are now in the 3D tab of the basic nVidia control panel (right-click on the desktop).  I haven't had NI installed in years.

 

Also, your AF settings are killing your GPU.  Back them down.

Do you have W2XP scenery by any chance?   

 

This will cause some stutters, it did on my setup, once removed I have had nothing but perfect smoothness experience anywhere locked at 1/2 of refresh.

Nothing. I just don't fly around London City. For now I didn't experience stutters anywhere else, except when in London.

No I don't. I wanted to use HD mesh, but it eats too much VRAM.

Do yo have the following library?
