[Benjamin Schmid <1055936@xxxxxxxxxxxxxxxxxx>]

I just tried the current daily built in a VirtualBox on a fast T4200
(software rendering) as well as natively (RS880 Gallium rendering) on an
Neo K350 Lenovo Edge 11 [Mobility Radeon HD 4250].

Speed improvement is indeed drastic, so 'unusable' is no longer
appropriate. Though 'making fun to use', neither.

Opening dashboard takes ~2-3s under VirtualBox, 1-2s as native 3D on the
Edge. Under Unity2D opending the dash occurs instantly including blur
effect on both environments. At least one interims shade grade is still
visible on trsuty. Also other desktop operations like window maximizing
are visibly laggy (~0.6s).

I recently tried the Ubuntu Gnome Alpha Build on the Edge, which I
remember quite snappy w/o significant lags while toying around.

Based on my user experience I would say it's "ok" now, but still a bit
annoying for daily use on low powered devices and VMs. Maybe turning off
some visual goodies in those environment could help to close that final
gap.

Title:
  Unity is unusuably slow with fallback software rendering (LLVMpipe)

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Incomplete

Bug description:
  I have Quantal Beta 1 installed in a Virtual Box VM, since unity-2d is
  no longer available it should be doing 3D rendering in software as a
  fallback since Virtual Box doesn't expose 3D hardware acceleration
  properly.  Any form of 3D animation takes, roughly, five to ten times
  as long as it should.  Opening the dash by clicking the Dash Home
  button takes about twenty seconds and you can watch the little spinner
  in the corner step through its animation in discreet chunks.  Opening
  a new window of any application it's also possible to watch the window
  opening animation in stages.  Operations within an application,
  scrolling, etc. aren't noticeably slower than on Precise, so I'm
  inclined to call this a unity bug but it's entirely possible it's not.

  I'm keeping the Quantal VM around for testing, so if you need further
  information or debugging output, let me know and I'll be happy to
  provide it.
