I know I have seen this mentioned before but cant remember what forum or thread but can anyone tell me what causes this and if there is a way to cure it?  I find it rather anoying to be sitting in the VC and have the ground shaking/twitching around the aircraft when looking out the window. 

 

I realize this is rather vague but I'm hoping its common enough I need not post a screenshot or explain system details etc.

You probably have "Cinema verite" turned on. Go to the "View" menu and switch it off.

Thanks for trying to help but that wasn't it.

I believe the bug has been reported, but apparently it still exists. This might be dependant on GPU drivers. A secondary effect is some z-trash on autogen, but I think I see this one less than before.

Be thankful you don't live in Tokyo. Occasionally I look out of my real window and the real ground is shaking.

Menu "Operations & Warnings", increase "flight models per frame" to 3 or more until the shaking disappears.

I reported (http://forum.avsim.net/topic/392087-shaking-grounds/) this bug months ago and it was confirmed a bug by tech support. They sent a bug report to developers but nothing happended. My feeling is that it has gotten worse and it's starting to be very annoying on my machine, esp. with GAs (NVIDIA, latest WHQL driver, WIndows 7 64).

My thinking is that this bug also causes scenery flickering and additional aliasing as the whole scenery in moving and shaking very fast.

I don't understand why such a obvious bug isn't adressed and users don't see it - I've seen it in many many youtube vids too.

 

And no, it's not cinema verité and not a flight-model problem, it's completely different and not related. 

Blaze - could you do a video and upload it somewhere? I've no capture software nor account. Would be worth to file a bug too.

My flight models per frame only go as far as 10 and made no difference what so ever, no matter 2,4,6,8 etc.

I just ignore it now, which is hard when it's like an earthquake outside.

I still get autogen z buffers (sides of buildings flickering) especially with osm scenery autogen.

Hi Trevor, please file a bug. This shouldn't happen.

Will do, have to find revelant files on the flight machine.

I filed a bug report too. Seems your correct it's worse in GA aircraft with latest Nvidia driver.  Sorry I can't do a video upload for the same reasons as you.

This comes from being closer to the ground. It makes ground-shifting more obvious but in general it's the same IMHO.

I really hope Laminar looks into this and hands it over to NVIDIA if necessary.

The latest nVidia driver has been giving me issues in Battlefield 3 where the textures get completely screwed up and sometimes even 3d geometry, but the most annoying thing is this stuttering even with 120+ fps. This may be partly responsible for the shaking of the ground/flight model as the graphics engine is out of sync slightly with the video driver.

 

The only fix was to roll back to driver 306.97 and I have fluid frames again. Unfortunately, nobody with a 7xx series card can do this as their device is only recognized with the 320 series drivers.

Hello,

 

I have the same problem here. Very enoying. I talked to the author of CZST (Beti-x). He knows about the problem. And I wrote it to Austin from Laminar R.:

 

Austin wrote me:

 

 

oh i see it

 

it is the fault of the custom scenery i think

 

they are using s t parameters that are too large, i think, thus there us not enough precision to display the textures perfectly

 

But this is also on default scenery.

 

He also wrote:

 

 

 

perhaps the video card has less floating point precision for s t params on the computer where you saw this

i dont know for sure, but i do know that i do not have time to get into R&D on someone else’s custom scenery pack

I could find out, that this is a problem of the Mac-Version of X-Plane. I saw videos on youtube without that problem. Can someone confirm that?

 

I hope 10.30 will fix it.

 

Greetings.

Hi PilotX, it's not related to Mac. My impression is that with customs scenery it's worse - but it's always there. The effect depends on the type of view, most obvious from inside the VC. Outside views only display the jittering during camera movement. Once the plane itself moves it's hard to notice at all, even from inside the VC. This might be the reason that you don't see it in some videos...

PS. Better live with it, ignore it, forget it. Laminar never mentioned to work on this.
