Slow perfomance with Nvidia driver

[Vive]

Performance is slow with the Nvidia driver. The display stutters. The animations in unity take 1-2 seconds to load. Screen tearing is observed while using firefox. Also, sometimes the screen flickers while using firefox. The same effects are observed when using the driver downloaded directly from Nvidia's website. This is a fresh install of Ubuntu 14.04.1.

Vive, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1406869

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.
