Description of problem:
My PC has a GeForce 6600 GT graphics card, fully OpenGL 2.0 capable. When I enable kde desktop effects, most of the effects are stuttering, and make for an unenjoyable experience.
The card itself if sufficiently performant though, because on the same system with the proprietary driver, I get fluent desktop effects.

Glxgears hints in the same direction:
- nouveau (desktop effects disabled): +/- 600 fps, fluent gears animation
- nouveau (desktop effects enabled): +/- 650 fps, but stuttering gears animation
- nvidia (destkop effects enabled): 3000+ fps

Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-0.0.16-27.20110720gitb806e3f.fc16.i686

How reproducible:
Always

Steps to Reproduce:
1. Setup a system with a GeForce 6600 GT graphics card
2. Enable kde desktop effects
3. For example, set desktop switching to use the rotating cube animation
  
Actual results:
The animation is stuttering

Expected results:
Fluent animations

Additional info:
I hope the nouveau performance can be improved. I much prefer to use the open source driver.

If more details are required, I'm happy to provide those.

Comment 1 Fedora End Of Life 2013-01-16 12:28:55 UTC

This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '16'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 16's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 16 is end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" and open it against that version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 2 Fedora End Of Life 2013-02-13 12:45:48 UTC

Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
