Apologies for the late-running of this update. I started drafting it earlier in the week and, um, forgot about it.
Week 27 Server Deployments
Just a reminder that due to the Independence Day code freeze for week 27, and the fact that the Lab is closed on Thursday 4th, Friday 5th July for a long weekend, there were no server deployments this week.
Server-side Baking / Appearance
Deployment / enabling should be commencing in week 28, most likely starting on the 9th July. To help spread the message, the Lab has once again blogged on the deployment of the new service, referring to it by the official title of Project Sunshine (which is a part of the Shining Project) and again included their video explaining what is going to be happening.
The majority of maintained viewers provided by both Linden Lab and third-party viewer developers are already ready for the new service, with only Dolphin, Exodus and Imprudence being without support. Hopefully, both Dolphin and Exodus will update shortly, but it will be some time before Imprudence is in a position to adopt SSB/A – the team has a fair amount of catching-up to do.
So, to borrow from the Lab. If you’re not already running an SSB/A capability viewer: “Don’t be cloudy and grey – enjoy Sunshine today” – and update your viewer!
SL Viewer News
A further SL beta viewer release was made on Tuesday July 2nd – version 3.6.2.278133 – with (among other things) further materials fixes, as listed in the release notes.
In other updates:
- The Lab has made a viewer repo public which contains various bug fixes and updates made available in the beta maintenance viewer. These include items such as the additional fixes for high-resolution snapshots (to prevent things like black rectangles appearing in very high resolution images). Expect to see them filtering through into TPV soon, and for the fixes themselves to start the SL release viewer possibly sooner.
- The “project interesting” viewer which contains viewer-side updates to complement various server-side interest list project updates is still undergoing work to fix all the blocker bugs which are currently preventing it from being made public.
In terms of the latter, Andrew Linden reports that he is looking to gather data which will allow for performance comparisons with things like scene loading pre- and post “project interesting”, to see help measure the improvements in the HTTP texture download changes implemented by Monty Linden.

What is a Reasonable FPS Rate?
In the last part of my week 26 update, I reported that the Lab has statistics which show that around 50% of users are running viewers with the Advanced Lighting Model option (“ALM” – formerly the Lighting and Shadows option and also referred to as “deferred rendering”) active, and that they further had data to suggest that up to 75% of users have hardware capable of running with ALM enabled “with reasonable performance” in terms of frame rates (e.g. an average somewhat above 10 fps).
At the time I reported this, I noted that:
However, given that fps is a highly subjective measure and somewhat dependent on a range of external factors (such as how many other avatars are in the region with you, whether you are moving around a lot or not, etc), the “YMMV” rule comes into play.
That the term “reasonable performance” is so nebulous sparked a debate during the Simulator User Group meeting as to what might be regarded as “reasonable” frame rates for a viewer running with ALM enabled (although not necessarily with any lighting & shadows options set). The broad consensus of opinion was that a rate of around 20-30 fps would be considered “reasonable”.
Part of the concern here is that while ALM is required in order to be able to render materials effects, LL might be overly optimistic in determining which cards have ALM enabled by default, which may in turn have an additional impact on new user retention due to people logging-in to SL and experiencing extremely low frame rates and not having any understanding on how to improve their experience.
