Linden Lab Issue ID: DEV-15352


 Description  « Hide
Key to this bug is a setting in the NVIDIA controlpanel (3D settings): "Threaded optimization".

If you suffer from this bug, add your SL viewer to the list in the "Program settings" tab, and turn it off.
Don't change the global setting, or other programs will suffer.

=======

Repro: Switch "Threaded optimization" on (global or for the SL viewer only) It may not reproduce on all machines.

=======

Symptoms:

After login, as soon as all textures in the scene have loaded, one extra CPU-core is loaded 100%, doing absolutely nothing.

=======

Possible root-cause:

Even the first CPU-core (the one SL is running on) is loaded to 100% if the texture-pipeline is idle.
When there are new textures to load, SL's core-usage drops to 66 - 88%. This does not show any difference in frame-rate.
Unfortunately, turning the NVIDIA setting off does not solve this part of the problem.

=======

Thank you again, Bailey Dharnen

=======

Original summary:

Soon after login, CPU usage climbs to around 100% on both cores - this happens in WindLight & Normal. Streaming music becomes stop-start as does any interaction with the Mac. Client often crashes on shutdown, and a couple of times I've had the Grey Blind of Death.
