Frame Rate drops update



For associated stories see the blog entries for September 14, and September 4

The bug first appeared after the 31st August update for Windows 10 Anniversary edition. However Microsoft said the problem was due to code inside the NVIDIA and AMD drivers.

Early reports say that the frame rate issue may have been resolved, at least for NVIDIA graphics users thanks to a driver update released today from NVIDIA, version 373.06

Of course it is too early to say for sure, so please keep and eye on the Linden Lab Jira BUG-37795

Update
Overnight many more people have indicated that this issue has finally been resolved and AMD have now also released a new driver to fix this problem.  AMD 16.10.1.    So if you have been suffering the frame rate issue, updating your graphics drivers to the latest release would seem to be the solution.

Frame Rate Drops - KB3194496 Windows update released today



Issue: Frame rate drops to around 3FPS when any SL Viewer tries to regain focus after another Windows 10 application has been run in the the foreground or after the viewer has been minimized.

Microsoft update patch  KB3194496  is again a cumulative patch which includes the OpenGL bug.

So if you previously removed KB3193494, KB3176938 and KB3189866 for this problem you will also need to block this update.

Frame rate drops update



We have updated our story about the OpenGL problems causing sudden frame rate drops in Second Life, because this issue now spreads from KB3176938 released on 31st August, to KB3189866 which was released yesterday.

KB3189866 is a cumulative patch, so if you removed KB3176938 is adds the code your computer is 'missing', back into the system.

The update is towards the bottom of the story here: Frame Rate drops story

NVIDIA setting you might like to try



Have you tried this setting in your NVIDIA control panel?  It won't work for everyone, but might work for you.

Under program settings, create a profile for your SL viewer software, and try enabling "Vertical Sync".

You need to restart your viewer after this change.  On our computers, frame rate increased from an average of 28-30 to 40-50.  Every little helps!

It does not fix the issues with the Windows 10 KB3176938 problem, but was a tweak we found along the way whilst researching the causes.

Sudden Frame Rate Drops (KB3176938)




Updated 14th September (notes at bottom)

Finding your frame rate inexplicably goes from whatever is normal to about 2 frames a second?

Well you can relax to an extent, there is nothing wrong with your settings and you are not being griefed.

But you are a Windows 10 Anniversary user, and you have the KB3176938 update and it installed around 1st September. This is the cause of your problems.



This is not simply a Second Life related problem, this issue is common to all OpenGL rendered applications, including D&D Online, Runescape, and Xplane, with emerging reports from the Minecraft community.

The problem occurs when any other application steals focus from your viewer such as a web browser or going to your desktop or minimizing the SL viewer.  The SL viewer then fails to regain foreground priority until your relog.   Sometimes it can take an hour for this problem to show itself, sometimes just a few minutes.

Linden Lab are aware of the issue, and their developers are actively pursuing a resolution for the problem.  However, at the time of writing this, the only workaround they can suggest is to consider uninstalling the hotfix patch from Microsoft.

If you cannot wait for a resolution to this, which now seems likely to be a further fix from Microsoft, and you are feeling brave, here is a guide to removing updates:  http://www.howtogeek.com/235474/how-to-roll-back-builds-and-uninstall-updates-on-windows-10/

There is also a thread to follow on the Microsoft site, specific to this issue.  Although it says it affects Firestorm, the Lab confirms it is all viewers with this update:  severe performance issues on Firestorm viewer

You can also follow the issue on the Firestorm Jira: http://jira.phoenixviewer.com/browse/FIRE-20034

There is now a LL JIRA for this issue.  https://jira.secondlife.com/browse/BUG-37795



extra note:
Please be aware that whilst the workaround of uninstalling KB3176938 does solve the framerate issue, if like me, you have always had Cortana disabled, the removal will of KB3176938 will  trigger it to become activated.

One of the 'features' of the Anniversary update was to remove the "off" switch for Cortana and once activated, it cannot be turned off again without hacking the registry.


14th September

If you removed KB3176938 alas the frame rate problem returns on the update KB3176938 released last night.  The patch is cumulative, meaning that it gives you all the updates to date.  If you are therefore missing KB3176938 because you removed it, it will be included in the patch from last night.

You can follow this direct link to the MS trouble-shooter which allows you to Show or Hide updates from your PC:   http://download.microsoft.com/download/F/2/2/F22D5FDB-59CD-4275-8C95-1BE17BF70B21/wushowhide.diagcab

You can run the troubleshooter and uninstall the patches as described here: http://www.howtogeek.com/235474/how-to-roll-back-builds-and-uninstall-updates-on-windows-10/

As previously explained, unrolling the updates will enable Cortana if you previously had it disabled, because a 'feature' of the Anniversary Update was to remove your ability to turn it off.

However by following this Registry Edit which I can confirm works as I have done it myself, will turn Cortana off in Windows 10 Anniversary.   Every caution should be taken when editing the registry.  Check and double check you have made any alterations correctly and back up your registry before meddling with it!  https://www.youtube.com/watch?v=iW1heCjMe3w
