I read that the secondlife.exe spends a large part of it's time performing the calculationis needed to generate the wind sound. Far more than would be needed to play some strung together audio files of whoosh noises. Supposedly this is because it's generating the values rathering than using prestored values, or something to that effect.
It was said that turning the sound off doesn't reduce the load the audio system puts on the processor, that the calculations are still made but just not sent to the computers's audio system.
Anyone know how much of secondlife's slice of processor time is devoted to wind sound generatiion?

I really have no idea but I am so desperately hoping someone who knows better than I do posts to tell you it cannot possibly be so. |

I can't imagine it taking all that much processor work, compared to graphics, corresponding with the servers, physics, scripts, flexy, shiny..everything.

You're trying to say that SL has bad wind?

Given that the wind generation also affects other items in world (sailing comes to mind), I would suspect some of those caculations continuing regardless of sound. _____________________

Current wind noise generation is CPU intensive.
https://jira.secondlife.com/browse/VWR-5308 That is not the thing I read. I can't find the thing I read. What I read made it sound a lot worse than that. _____________________

Best thread title ever. Even better than "Jiggling Boobs", "Thigh Stretching" and "Just created my first character, accidentally chose Furry".
Also a damn good question. _____________________

Best thread title ever. I hate it when I make a typo in a thread title. I'd pay to have them corrected. _____________________

It would be better if I had typed "spent" instead of "spend", or noticed it fast enough to change it. I hate it when I make a typo in a thread title. I'd pay to have them corrected. _____________________

Given that the wind generation also affects other items in world (sailing comes to mind), I would suspect some of those caculations continuing regardless of sound. On the server, there's a wind simulation (it actually crosses sim boundaries, so a "gust" on one side of the border affects the wind on the other side); the wind velocity (speed and direction) is available to scripts, so that's how sailboats (and wind chimes, and weather vanes, and windmills...) can respond to wind. I guess there must be a steady stream of output from this simulation sent to the client. In the viewer, not only do we hear the wind, but it can affect pure client-side stuff like particles and flexi prims. _____________________
