  1. I just tested on the LL Viewer Second Life Release 6.4.21.561414 (64bit)
    Setting the debug ImagePipelineUseHTTP to FALSE allows you to still fetch textures over UDP.

    Just for fun, I went to Lagland region (specifically set up for texture fetch tests)  & tested clean cache fetching all textures over UDP & then relogging with clean cache & ImagePipelineUseHTTP set to TRUE to fetch over HTTP.

    Times taken to fetch all textures on the region:
    UDP: 23 minutes!
    HTTP with HttpPipelining disabled: 2 mins 37 seconds.
    HTTP with HttpPipelining enabled: 1 min 15 secs

    On my system, fetching textures over UDP is so freaking slow.
    It's also nice to see how much faster HTTP texture fetch is when pipelining is enabled too.

     

    Note: Setting ImagePipelineUseHTTP to FALSE also disables HTTP Pipelining & setting ImagePipelineUseHTTP to TRUE again & relogging does not automatically enable Pipelining. Make sure to set HttpPipelining to TRUE when testing fetching over HTTP

    Edit to add:

    Location: UK
    ISP: TalkTalk (possibly more *****e than Virgin!)
    Download speed at time of test: 41 Mbps
    Upload speed at time of test: 10 Mbps

    Hi,

    I come across this topic because I got warning from my antivirus, that Dullahan tried to access my camera. Is this normal? I covered my camera on my laptop tho, but I am just curious why is it trying to access my camera? It is not from my skype or chrome or anything. I got that since I bought a youtube tv, adding my playlist to the tv and tried to play it. Then the Dullahan warning comes up.

    Dullahan is basically a Chrome based web browser inside your viewer & if you/the viewer is within range of a media enabled object that tries to access your webcam then you will get this prompt, the same way it will happen if you visit such a web site using an external web browser.

    Which viewer do you use?  I'll tell you how to see all the media sources the viewer is connected to so if this happens again you can see which web page might be the culprit.  The instructions might be different on each viewer.

    Googling dullahan_host.exe brought me here...

    Not using Firestorm, but I am seeing 12 dullahan_host.exe on task manager each consuming almost 9 percent of CPU.

    And I haven't even got SL running right now.

    My system is SLOW and running SL is like walking in treacle. Is this connected to this topic?

    Does anyone have advice for me please?

    Emma :) 

    Sometimes the dullahan_host.exe does not shut down when you exit the viewer, especially if you are still using Windows 7.
    Having these ghosted Dullahan processes running will absolutely affect the viewers performance.
    When logged out of all SL viewers, just end the Dullahan_host processes via task manager & check in the future that none are left running after logging out of the viewer.

    You can abuse this to get other people banned from the land by changing the last part of the URL you are given. To ban for example Dan Linden(Sorry Dan!), provided he is on the land as well, but he wouldn't be too happy about alt detectors: /?3de548e1-57be-cfea-2b78-83ae3ad95998.

    So basically you can go to any parcel using one of these devices & get everyone on the parcel banned by this system very easily.

    Sounds like a fun game!  :D

    Why does disabling the water rendering change the skies as well? Water is rendered even when you're up 3000m in the air and can't see it so it used to be a performance optimization to turn off water rendering in skyboxes. But now with EEP it messes up the lighting completely in most cases.

    It's a known bug
    BUG-229028 - [EEP] When ALM is enabled, disabling water rendering breaks the sky

    The "high tides" problem, as I understand it, is really a viewer issue, needing a little more sophistication about what to assume is water height in non-adjacent void: Instead of extrapolating he water height of the agent's current region, use the height of regions directly (not diagonally) adjacent that void.

    This is not an easy problem to solve unfortunately.
    The "high tides" bug described on this thread has been fixed & reverted several times because the fix causes all standalone regions that use a non-default water height to have broken water rendering, which causes even more screams then the current behaviour described here.

    See https://jira.secondlife.com/browse/VWR-29065 & all the linked issues.

    How is such research done? I understood that as of some years ago viewers were no longer permitted to reveal this information except directly to the servers, but I guess the Lab may publish it—but where?

    LL send the TPVs listed on the TPV directory regular stats showing viewer versions, number of sessions, number of users, hours online, average session times, median session times, and crash rates.

  8. I've been playing with this cool free AI app called Wombo today that takes an image & adds music & lip syncing.
    It works really well with avatar images & the results are hilarious.
    I thought you guys might enjoy playing with it too.

    Information here: https://www.wombo.ai/

    Here are some I made earlier  :D

    I just put it here and watch as i can't do much.

    Since the last region restarts I have an old soundscape objects that since today gives me the error "Too many error returns for script." every couple of seconds. Tried that in 3 different regions with the same result.

    I can't reset it because it's no mod, and re-rezzing does not help either.

    I guess it's something with the last Region update:   Second Life Server 2021-02-01.555570

     

    Looking at Rider's comment on BUG-230126 - "Too many error returns for script." error from a HUD while on regions on Second Life Server 2021-01-20.555189
    it's likely to be a script problem the creator needs to fix.
    Where is the soundscape object rezzed?
