Description bellekci 2015-04-23 18:09:11 UTC

I have seen that when there is no monitor attached or only a USB-monitor is attached to the computer, the performance of openCL is very slow. X server was running in all cases.

Can anyone confirm this?

Please, simply compare the performances (speed) of the cases when a normal (VGA, HDMI,etc) monitor is attached and when only a USB-monitor is attached to the computer.

my kernel: 3.19.2
