Hi,

we've testet the ProBook with Cat. 13.9 and did not notice such problems. I would try installing a new graphics driver, if possible directly from AMD.

Hi!
Thx for your response.used driver was pre-installed or downloaded and installed from hp download page??may i ask you for graphics performance test with unigine heaven benchmark (http://unigine.com/products/heaven/download/ (http://unigine.com/products/heaven/download/)) with these settings (http://s27.postimg.org/bdoqp5j1v/Screen_Shot122.jpg (http://s27.postimg.org/bdoqp5j1v/Screen_Shot122.jpg)) please??if it is possible give me a feedback with results please.basic version is free and without ads.
or if you have installed GTA4 or F1 2012 then try benchmark test in game options and it will show you which GPU is used.thx.

Hi Till.
May I ask you for printscreen of used AMD 8750M driver properties tab from device manager please??something like this(http://www.eightforums.com/attachments/graphic-cards/9838d1350967716-win-8-amd-switchable-graphics-faq-amd_signed_intel.jpg)
