Suspected slowness 14.04 HD 8330 using opensourced drivers.

[open2reason]

I am running 14.04 latest daily 64bit (AMD a4-5000 HD 8330 + 4GB ram) and have noticed what I think to be a slowdown and general sluggishness when using http://www.kongregate.com/games/pree...-tower-defense browser based 2d game when comparing the running under 12.04.4 with that under 12.04.4 . In 14.04 I am using the latest open sourced drivers as illustrated under Ubuntu Software > Additional Drivers.

Can anyone please advise me of a command I can use that will allow me to measure any difference between the 12.04.4 and 14.04 performance?

Thanks a lot.

working good here on my AMD HD 5450 Silent w Gallium 0.4 on AMD Cedar

A whole can of worms.

Glxgears on 12.04.4 with VESA: KALINDI using AMD/ATI propriety FGLRX (post release updates) gives a score in the range of 1276 - 1235
Glxgears on 14.04 with Gallium 0.4 on AMD KABINI using x.org xserver AMD/ATI display driver wrapper from xserver-xorg-video-ati (open source) gives a score of 60.

At this point I attempted to change the 14.04 system from open source to AMD/ATI graphics accelerators from fglrx-updates (propriety) and the update system failed with an error while applying the new drivers.

Will have another attempt tomorrow to recreate 14.04 results and errors.

Any hints as to filling in a launchpad request if one is requested / required?

Thanks.

You have to create a launchpad account here :

and the rest is self explanatory.

Zika,
thanks for your tip. I'll give 14.04 another try in a couple of weeks or so.
