My configuration for Bulletsim in OpenSim.ini from versions 0.7.6 to
today actually 0.8.0.3
[BulletSim]
; Avatar physics height adjustments.
; http://opensimulator.org/wiki/BulletSim#Adjusting_Avatar_Height
AvatarHeightLowFudge = -0.3 ; Adjustment at low end of height range
;AvatarHeightMidFudge = 0.0 ; Adjustment at mid point of avatar
height range
;AvatarHeightHighFudge = 0.6 ; Adjustment at high end of height range
;; Default values are:
;; AvatarStepHeight = 0.5
;; AvatarStepApproachFactor = 0.6
;; AvatarStepUpCorrectionFactor = 1.0
;; AvatarStepForceFactor = 1.0
;; AvatarStepSmoothingSteps = 2
As you can see I change only AvatarHeightLowFudge = -0.3
Please try it and comment the results.
Kindest regards

As I said, this has been going on for over a year. (I first noticed it in
November 2013.) That's how many OpenSim versions?
The time period also covers several versions of Firestorm, some significantly different
to the latest version. I normally use Firestorm for OpenSim, but sometimes I try other
viewers, including Cool and Kokua. The vibration is the same in all of them. (My computer
can no longer run Imprudence or any other truly "v1" viewers.)
Luisillo, it sounds like you already have the configuration change, because you say you do not have the problem with a
4'5" avatar. In my OpenSim standalone and all the grids I have been in except one, the vibration is noticeable on
a 5'4" avatar. ("Noticeable", not "bad".) My normal avatar is about 4'6", but on this one
grid where the problem is reduced my avatar is 5'1" tall. Note this is only grid configuration change, the numbers
for my avatar are the same. Perhaps that is a clue.
... Or perhaps not! While typing this email, I took a minute out to chat with
the tech chief of the grid where the problem seems better after the config
change. He couldn't understand how the change helped, because all he'd changed
was database access, to better distribute database load. Now, I immediately
thought of a bug InWorldz just uncovered last month: While an avatar is moving
there is constant database access. I don't know how OpenSim is threaded, but
with the wrong threading or locking arrangements physics calculations could be
paused by database access.
I would not be at all surprised if this bug (constant database access while avatar is
moving) is true of current OpenSim, especially because up-to-date OpenSim grids display a
bug which may be a symptom: when a vehicle crosses between parcels with "restrict
sounds to this parcel", the vehicle sounds go quiet for as long as the
sound-emitting prim is not in the same parcel as the driver. (This does not happen in
Second Life, so we know it's not the viewer being that strict.)

Hi Ethan,
I detect this problem on avatars size 3'10" / 46 Inch / 118cm. With
Singularity and Firestorm viewers.
What viewer are you using and the OpenSim Version and your avatar size?
(I think the limit for this problem is < 120cm.)
I am using Firestorm (last release) on OpenSim 0.8.0.3 and I have not
this problem. My size is 4'5" / 53 Inch / 135cm. But with Singularity
and other viewers I have this problem.
Best regards,
Luisillo

Hi. When walking on sim terrain in a short avatar, I get really nasty
vibrations, making my view shake and everything. It's bad enough that I can
hardly walk around. This has been going on for over a year now, but I just
found it can be greatly reduced by a config change. I'd appreciate any info on
what config option it might be, and why the default is so awful. (Would a
change to that option make OpenSim more likely to crash?)
