Any ideas how do I turn on GPU acceleration in Lightroom 6?
I meet the minimum requirements (Win 7 x64, 1GB VRAM, OpenGL 6.1 ) and as advised in "learn more" I did check my graphic driver which is at the latest version.
Still I am getting message: "GPU acceleration was disabled due to errors"
Any help apprecited

There are issues with some AMD graphic cards. Adobe and AMD are investigating. In meantime, I suggest you switch off GPU acceleration.
You can also install an "old" version from april 2014 (V 14.4) which works with Lr6 after having un-installed your actual actual drivers.
You can find it here: http://support.amd.com/en-us/download/desktop/previous?os=Windows%207%20-%2064
Be aware that with this driver you could activate the GPU Acceleration but it's possible that you didn't obtain any benefit...bug or not nobody knows...
