XP11 beta3 micro-stuttering

Recommended Posts

One thing I like XP11 was its smooth fps. But since I upgraded to beta 3 I got this micro-stuttering which is the thing I hated most while flying P3D. Now I got this in XP11!

 

I upgraded the video card from 980 to Titan X at the same time. I uninstalled and reinstalled Nvidia driver and no difference.

 

Ironically P3D now runs way smoother with new card so I doubt it's due to card upgrade.

 

Anyone else has this stuttering thing with beta 3? This is really a show stopper to me.

No stutter here - still beta so have to wait till it gets sorted out see if you can go back to PB2

Thread optimization off ...  

 

this should be pinned  ....

 

Doesnt matter here on or off same performance - XP works great - they just have to get the fps up

I double triple checked that thread optimization is off. Really puzzled why. Now my P3D is smoother than XP11, this can't be right...

 

Are there other settings in video card driver I better pay attention to?

I am also seeing a few micro-stuttering in XP11 b3. And they were not there with b1 and b2. Not much though, but still enough to notice.

In your nVidia control panel, there may be a second tab which can be assigned to something other than the standard settings.  If you have it assigned to X-Plane and have not changed the settings there, what you did on the front page will have no effect.  Not at my nVidia equipped machine right now, but that should be worth checking.

Same here on my GTX 1070. I also had better performance in B2. I have threaded optimization off.

Yes I turned of TO in XP11 profile too, so it's definitely not thread optimization issue.

 

Maybe my b3 installation is broken?

You may want to go back to PB2 not seeing much of a reason to use PB3 - also you could move out plugins and see if there is an issue with one of them

My old GTX-980M is handling XP11 rather well, much better than P3D ever did.  I did however ensure Threaded Optimization was off and I also don't run my settings at their highest either.  I'll get occasional stutters, but typically at low altitudes within large cities, like Los Angeles but once outside of that area, smooth.  I'm not running any external weather, nor any plugins outside of the DataRefEditor.

Hmm, what is that? as I did not see it being an option on the menu (have to look for it). I am running the demo which was just installed yesterday and I also noticed this stutter problem.  Compared to XP10.51, although XP11 looks much better, if this stuttering and performance issue persists then it will be really bad.  I am counting on this being a beta issue.  First I thought it's due to my rather old i7-2700K oc 4.8 Ghz + GTX980 combo, but it can't make sense that XP 10.51 runs pretty good and not XP11.  Is this a known issue to LM yet?

Threaded Optimization is an option in the nVidia control panel: it is not an XP option. Open the nVidia control panel, go to 3D settings and then to the X-Plane profile and turn threaded optimization OFF. (If 10.51 runs well on your system it might be off already... although it is on by default). But as posted above: XP11 performance needs to be optimized yet.

Thanks.  Jeroen, did you buy a license for Xp11 already or just testing the water with the Demo.  Coming from XP 10.51 the env. of Xp11 is very impressive.  Support for second monitor is definitely a step up.  I was thinking of getting license and gradually install scenery but this stutter stopped me right now.  The stutter is what drove me nuts in P3D.  I had assumed that it's due to ORBX, so I just cleaned everything out and see if having no ORBX stuffs solves it.  If XP11 delivers all of the P3D stuffs will be thrown out.

I don't think I touched this with XP 10.51 either but will give it a try.

You must turn off Thread Optimization, that's thing cuts my fps by half. 

 

But still beta3 can have some sever stuttering. At LOWI I got 30fps but the stuttering is so bad it feels like 5fps, totally ridiculous. 

 

The thing is beta2 runs fantastically on my PC, while beta3 cut my performance by at least 30% or more. I really shouldn't upgrade to beta 3. I want to go back to beta 2 but don't know how.

I wouldn't be hasty in going back to a previous beta right now.  Since XP11 is still in a beta stage, there is still room for improvement as well as the aforementioned optimization of textures.  On my end, I couldn't be happier with the performance of XP.  I've been running several flights in the latest beta, with a very nicely customized lua script for the clouds.  There also appears to be a vast improvement of the flight model of the default Cessna, which makes my flights all the more enjoyable.  I have both XP10 and 11 installed on my rig, but now I am running 11 all the time.  I've grabbed several new airports from the freeware/donationware section of the XP org, and everything is running fine.

The best thing to do in X-Plane after every update is to dump your preferences and start fresh, then see if things change. This is normal for the duration of X-Plane builds.

 

Note: You are starting fresh as if you just installed the program, not like editing a fsx/p3d config file.

I tried clean installation several times with beta 3, including dumping those preference files etc. No helps. I guess somehow beta 3 just doesn't run well on my system for whatever reason. 

 

XP11 beta 2 was really nice, well over 20fps even flying those extremely heavy Ortho4XP sceneries. I began to miss beta 2 more and more. Hopefully beta 4 is coming soon and thing will be back to normal performance wise.

I have noticed more stuttering in b3 as well after it initially being very fluid. not sure if xenivro has caused any stuttering or not...

I don't think it's caused by XEnviro, unless adding that plugin is pushing your system over a threshold it can't handle. I've been testing XEnviro and haven't seen any stuttering. It does drop my frame rate a little compared to default XP11, but I'm still over 40 fps and often higher. 

 

If the stutter goes away when reducing world/graphics detail, then your settings are just too high for the current beta on your system specs. I don't think XP11 is completely optimized yet, so we should see some improvement before final release.

im not complaining, its not a horrible stutter , happens mainly taxiing at airports in turns, but i have to point out it wasnt there in b1 and b2.

Yep,

 

Have to agree, does seem to pause /stutter even maintaining 30fps...not sure why.. clouds of course kill it and lets face they are pretty rubbish!.I know LR are still working on the rendering engine etc and this is Beta, but got ask if v10 was working fine for most users and XP11 is an improvement and drastic amounts of code have not been changed or even improved...."I dont know this I am guessing here".....then why does XP11 not run so well?

 

If the platform is progressing forwards as we all want it too then one would rightly or wrongly assume it would be better out of the box performance wise...I am only summarise here on this point and no doubt a member of the LR team could answer this...

 

Still looking forward to see the next Beta iteration then maybe I will pull that trigger...

 

Cheers

Have you worked with FlyWithLua?  That works as a great, free alternative to paid weather generation.  Creating a lua script is pretty easy and once you load a flight, the script loads right along with it, seamlessly and effectively.  I've been able to transform the dull, dark cloud textures into payware quality with just a few lines of code. :)

Because there's more stuff in it than there was in v10?  :smile:

 

Also that it's a beta and not optimized yet? We seem to forget that often, in these threads. But it's also a result of new features.

 

Just one example: Extended dsf loading (more detail in the distance) used to be an option in v10. Now it's standard and always enabled in v11. That requires more resources on the user's computer, and Laminar is assuming that people are steadily upgrading their computers with enough RAM to run that feature. That's just one example. There are probably a few dozen more things going on under the hood that are different in the new version, like the new physics based rendering, and the new lighting and haze programming.

 

 

If the platform is progressing forwards as we all want it too then one would rightly or wrongly assume it would be better out of the box performance wise...I am only summarise here on this point and no doubt a member of the LR team could answer this...

 

I think it's a mistake to assume that when a new major version of a flight sim is released, the first priority of the devs is to make it run better on existing hardware. That's not usually how it goes. New versions mean more hardware demands. Remember FSX when it first came out?

 

The last version of X-Plane added features like HDR that couldn't be run well on most user's hardware until we caught up. Some people still can't run HDR on fairly top-end machines, although I think that's mainly due to the popularity of higher resolution monitors. I've been able to run HDR for the last year because I'm on a 1920x1200 monitor and not pushing that many pixels.

 

So this is something to get used to. New version = cool new features, but you may need to back down the eye candy to run at the same frame rates you had in the last version. Or buy a new computer or graphics card. Or don't use an ultra-high res monitor.

:wink:
