Singularity provides update to address AMD Catalyst driver issues

Posted on by Inara Pey

singularityUpdate, March 21st: AMD have release a new set of Catalyst™ drivers, version 15.3 beta, which include a potential fix for the rigged mesh issues – see my notes here.

As I’ve previously reported in this blog, recent AMD Catalyst™ driver updates have resulted in numerous issues for SL users running AMD graphics cards and attempting to use the latest driver updates. These started with the 14.9.1 drivers, but which became particularly pronounced with the  14.9.2 drivers failing to render rigged mesh unless hardware skinning is disabled (see: BUG-7653), problems which increased with AMD switched yo automatic updates with the release of their 14.12 drivers.

In December 2014, Yoho Waco offered a workaround for the problems affecting more recent drivers (e.g. 14.12) using the 14.9 DLL files to overcome some of the issues presented by those drivers, and which should work for most viewers. With Yoho permission, I offered his workaround as an article in its own right, and DMC Jurassic reported the same approach could be used with 1.4.4 driver DLL files to resolve issues caused by both the more recent driver updates and those cause by the 14.9.2 driver update.

Recent AMD Catalyst™ drivers (1.4.9.2 onwards) have been problematic for Sl users, presenting a series of mesh rendering problems as a result of changing openGL support within the drivers (image courtesy of Maestro Linden, click for full-size)

Now the Singularity team have stepped up, offering their users who use AMD graphics cards and who have particularly been affected by the rigged mesh issues found when using the more recent Catalyst™ drivers.

Version 1.8.6.6157 of the viewer, released on February 27th, 2015, is labelled as a “supplemental” update to the viewer because, as the release notes state, it only provides a fix for this particular set of problems, and offers no additional updates to the viewer as a whole.

Therefore, if you are not affected by the Catalyst™ driver problems, there is no need for you to update. However, if you have been affected by the problems, then this update could well be for you.

SL project updates week 9/1: server, viewer

Server Deployments, Week 9

As always, please refer to the server deployment thread for the latest news and updates.

  • There was no deployment to the Main (SLS) channel on Tuesday, February 24th
  • On Wednesday, February 25th, all three RC channels will receive the same server maintenance package, which comprises:
    • A server-side fix for BUG-8297, “Unable to teleport anywhere using SLGO”
    • Improvement to server logging.

The SL Go teleport issue only affected users running the SL Viewer (SLV) supplied by OnLive, who run the SL Go service (it did not affect those using Firestorm on SL Go), and was the result of a recent server-side code clean-up which meant that OnLive’s SLV was essentially using an invalid channel name when instigating teleports, causing them to fail.

OnLive implemented a workaround for the issue on their side of things on February 3rd, however, the update included in the RC package noted above provides a fix on LL’s side of the connection as well.

SL Viewer

On Tuesday, February 24th, the Maintenance RC viewer, version 3.7.25.299021, was promoted to the de facto release viewer.  This release includes a large number of improvements and fixes to the viewer, as listed in the release notes.

This currently leaves just the new log-in viewer RC (version 3.7.25.298971 released on February 17th) and the Experience Tools RC (version 3.8.0.298001 last updated on January 15th) in the release channel for the time being.

Experience Keys / Tools

The initial release of Experience Keys / Tools is still awaiting various back-end updates to clear the Lab’s QA department, with the viewer remaining at RC status until that happens (see above). As previously noted in my Experience Keys reports, the initial release of the functionality will not support grid-wide experiences, although are likely to be on the roadmap for future enhancements.

Once released, the current iteration of the functionality is liable to be allowed to run for a number of months before the Lab starts making  (or releasing) updates, with Oz Linden commenting at the Simulator User Group meeting on Tuesday, February 24th, “there will be another round of improvements to Experiences at some point, but we’re going to give the first round some time to be adopted before we go too far with those.”

Group Chat

Group chat work is continuing, with the recent changes to handling server lock-ups reducing the number of reported freezes.

Simon Linden is also continuing to look at the code side of things, and specifically issues with group chat visibly “stalling” which switching between chat tabs and / or as a result of moving between regions. This work has been the subject of a series of “mini-tests” during the Server Beta User Group meetings held on Thursdays, and resulted in some recent code updates. Commenting on this at the SUG meeting, Simon said, “The new code also showed me details about one way the system fails, so I hope to make that better at recovering,” so further updates can likely be expected, although this may not be as broadly visible to many users as the initial group chat improvements.

Firestorm TTT: command line shortcuts

Posted on by Inara Pey

firestorm-logoThe Firestorm Tool Tip Tuesday video for Tuesday, February 24th offers insight into using local chat as a quick means of using a number of viewer-related and other command options.

This is achieved by using what Firestorm calls the “command line options”, which can also be found in some third-party viewers (Singularity being another which uses the capability). There are essentially pre-configured shortcuts which allow you to do a number of things; for example, you can quickly step your draw distance down / up, or teleport to a specific region or height within a region, rez a platform, and so on.

Firestorm is one of several TPVs offering "command line" shortcuts which can be typed into local chat to achieve a number of things - the the full list of options via Preferences

In the video, Jessica takes viewers through several of the more popular command line options as well as looking at some of the commands people might not be so familiar with, such as the calculator, turning your Firestorm AO off / on, clearing-down your local chat history display, and so on. She also touches upon customising the command names to make them easier to remember and use, if you need to.

So, if you’ve never looked into using chat command via the command line option, this is the video for you!

Lock’n’load: it’s snowballs 2: this time it’s Firestorm!

Posted on by Inara Pey

On February 6th, residents and Lindens met in-world for what proved to be a challenge met with gusto and delight: the first in-world snowball fight involving Linden staff in a fair while.

As I was able to report from the front lines (when not picking myself up off the floor and dusting myself down after getting splatted by a certain Mr. Gibson Firehawk … several times 😛 ), the event was held in the Winter Wonderland created by the Lab and the Moles to help demonstrate the forthcoming experience keys / tools.

Well, with Winter Wonderland liable to be closing its doors in March, due to springtime arriving, the gauntlet has been once again laid down, with a challenge handed out to one and all for a further snowball fight – only this time it comes from the Firestorm team!

The challenge was given out in a Firestorm blog post, which reads in part:

The Firestorm team wants to do it again! Snowball fight pt 2! For those who couldn’t make it to the first one this is your chance to get involved and have some old school fun! We have extended an invitation to the Lindens as well and hope some of them will join in too.

February 6th proved to be a huge amount of fun for everyone involved, something which even recalcitrant weapons vendors and a healthy smattering of lag amidst the snow could do little to dampen.

So… if you missed out the first time around, or if you want to do it all over again, be sure to be in-world at the Snowball Warzone in Winter Wonderland by 13:00 SLT on Sunday, February 22nd!

Server Deployments

As will already be known, there were no server deployments this week.

SL Viewer

A new release candidate viewer appeared in the release channel on February 17th in the form of a new login viewer. Version 3.7.25.298971 sees the three log-in options buttons on the original log-in screen update replaced with a single button.

February 17th also saw updates made to the Maintenance RC viewer, which was updated to version 3.7.25.298971, while the Tools update project viewer was updated to version 3.7.25.298862, having been held over for release from week #7, due to the Valentine’s weekend / President’s day no change window.

Group Chat

The was a further back-end update to the group chat servers during the week, further implementing the stability improvements the Lab has been working on to solve issues of chat appearing to freeze when switching between tab / issues with the chat servers themselves locking-up.

Other Items

Attachment Issues

As per my last report, there is still considerable debate about the nature of attachment issues, particularly those reported via BUG-6925. A concern is that while (as noted last time), the Lab considers there to be multiple issues occurring, BUG-6925 has already had some initial investigations carried out by the Lab, and these might be getting missed as the Lab considers the wider problems and attempts to categorise things. There is also a concern that the BUG-6925 issue in particular is AIS-v3 related, which could result in a significant increase in reported issues should that code be released by Firestorm as a part of their planned update.

Suggestions have been made on additional logging that might be added to the viewer to further pin-down precisely what is happening in the various circumstances where attachments are detached / re-attached or appear to be detached but aren’t, etc., and the issues are continuing to be examined by the Lab.
