I need your help.
We use a miniPC Intel® Atom™ D2550 (dual-core ) with Nvidia graphics cards GT610 and we are facing an issue that has a major impact on the quality of the service that we offer.
The problem consist in a considerable increase in CPU consumption (+100%) that occurs when you turn the screen rotation.
In practice, once we apply a rotation of any moving object, such as a video, it causes a huge resource consumption that however is not present in normal mode.
The tests were carried out on different versions of the operating system:
Fresh Install Ubuntu 12.04 x86_64
Fresh Install Ubuntu 4.13 x86_64
Ubuntu 12.04 x86_64 with kernel 3.9.10
01/06/2013 Fresh Install Archlinux x86_64
The versions of the graphic server used are the following:
- Xserver-xorg 1.11.3
- Xserver-xorg 1.14.2
The video card is a GeForce GT 610 and driver versions used in the tests are:
Was also performed a test with an open driver for Nvidia cards (Nouveau) that did not show this problem.
