Avatar skipping while turning problem with high end hardware

I and at least one other person are experiencing an odd behavior when turning their avatar. The avatar will skip while turning, its as though it were a film and 20 frames have been edited out but it isn't frame rate related as the stats bar reports 30fps and upwards of 75fps.

Observed behavior in a private sim(Furnation Alpha) Can't teleport so I haven't tried on the mainland.

Jittery frame rates and off the scale FPS red bar while the green indicator jitters rapidly at 20-30 fps

Jittery movements of avatar when walking

Jumping or skipping movemnt while turning, in other words the view is not smooth when turning and skips around sections of the wold around me, usually expances of water. Does not occur when inside a building unless there is sim water visable. Also does this at high altitudes.

Increasing draw distance to 512 slows the skipping down some but decreasing it to 64 makes the problem much worse and the game is unplayable.

Decreasing video memory in preferences has little or no effect

Increasing AA and AF filtering manually on the the video card drivers to max has little effect but sure makes the picture purdy, turning them off just makes the world ugly.

Setting the image quality to max "High Quality" seems to slow the jittering down some, setting to "Performance" makes things much worse.

AGP accel. off made no difference

After more testing I have found that if I run at Hight Quality, turn my AA and AF filters to max, increase my draw distance to 256 meters and turn on local lighting the problem does not appear. Unfortunatly I am only getting around 15 fps.. very pretty 15fps though. Seems if I load my machine down so I keep framerates under 20 fps I don't have the skipping.

Hmmm, its not doing it now after the update...

Mine still does it. I have noticed that it takes awhile in game before it starts to do it. I thought at one point it was linked to sitting (like it will start after you sit and get up the first time), but that is not the case. For me it still does it in the new version but maybe just takes a bit longer time in game to start showing.

I uninstalled SL completely then reinstalled, might try that and see if that does anything for ya. I haven't been in game more than a few minutes so it may well be.

Well drat, its back...

Tried clearing the cashe, made it a lot worse until the cashe filled and the world filled.

Went to debug and turned off different renderings, simple rendering had the biggest effect making it basically to where I could only face either east or west ( roughly).

Curious: Do you see the skipping in other avatars when they turn, or is it just your own that displays this odd behavior?

This sounds very much like the client isn't adjusting for the extra available cycles, and is running out of animation before you finish the turn. I'm kind of amused that it's possible to have hardware that's too good for SL.

Hmm, no. Other avatars behave relatively normal as they turn while watching them on the 6800 machine. Watching my avatar turn from an alt on a different machine, my avatar doesn't skip consistantly but sometimes it rotates normally, other times it vibrates in place like thumping a door stop spring then continues to turn.

I noticed I can achieve higher client fps than sim fps at times. Funny thing is it has no seeming effect on the skipping.

Here is a kicker, when I run Fraps, it does not skip. This tells me that my system is too fast for SL... I have never been in this position before.

A little necroposting here but I think this thread needs an update. For a long while now the effects seemed to diminish enough not to cause problems but I just updated my drivers for the card and the problem came back in spades. I sent in a bug report and Dan Linden contacted me about it and suggested I look at some AMD support forums as a lot of folks were having problems with the X2 AMD duel core processors. They recommended updating the core AMD drivers. Doing this seems to have cured the problem in my instance. Woot, thanks Dan.

I have always had these problems, there needs to be something to be done, but I am not keeping my hopes high. Another problem I have is when I type it actualy causes the game to stop responding until I stop. Horriable for typing a long sentence!

Thx for the heads up Kathmandu, I had the same exact problem on my new system(AMD64X2 3800+) So far this seems to cure it!
