Comment 15 for bug 1046497

I have tested four different types of graphic cards running Unity using Intel Core 2 Processors and found this:

- AMD64 edition performs so much slower than i386 one, and it's more noticeable when playing Adobe Flash videos.

- The Unity interface has some glitches using Nvidia GeForce 8500GT with nouveau drivers, and performs somehow slow with the propiertary ones due to insuficient graphic procesing power.

- Intel G33 and ATI Radeon Mobility X1400 perform slow due to insuficient graphic procesing power.

- Using xorg drivers, ATI Radeon HD5750 performs somehow slow under 32-bits edition and very slow under the 64-bits. Using fglrx, performs very slow in any case.

So I conclude:

- It will be very difficult to end users to know at this time which graphics procesor to buy, since these tests suggest lots of cards are experiencing issues right now and it's not very obvious which of them are before buying.

- It is better for me to stay using Ubuntu 12.04 in almost two of three computers I have, specially when derivatives as Xubuntu have many bugs at this time.

- This is a big thread for Ubuntu and will decrease its adoption by a lot, since it concers for many people a critical part of the operating system: the interface.

- And the most important: Ubuntu livecircle must improve to stop these big issues to happen to time to time. Perhaps developers of many Debian packages are only interested in finding bugs just before next Debian release rather than Ubuntu's ones, so these packages enter deeply untested into the final version of Ubuntu.
