If this thread reply is to me, nVidia's priorpetary driver is far better on reliability and stability compared to AMD and Intel graphic drivers. Occasionally, I get the following message with Intel graphics.
Code:
[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
[drm] Enabling RC6 states: RC6 on, RC6p on, RC6pp off
I never have instability issues with nVidia graphic cards like I get above. Also I do not get any video tearing when VSYNC is enabled for OpenGL and/or X-Video. Intel fixing the video tearing bug is not much of an issue for me compared to stability and reliability problems that I am having with Intel graphics in Linux.
I have no problems using OpenGL for video playback in fullscreen with nVidia graphics on my other systems. When I use Radeon graphics using open source drivers, video playback with OpenGL works even in fullscreen. I use X-Video for Intel graphics, so I can have the reliability and stability. My computer with i3-3225 is fast enough to handle 1080p content so I do not need VA API. My other computer with T7300 CPU that has a GeForce8 8400M GS can use VDPAU, but lately MPlayer has issues with VDPAU.
From I learn in the past of other Intel hardware like WiFi, relability and stability does not get fixed. Intel just provides the software for their hardware to a working condition and Intel expects open source developers to fix the issues if their drivers have any or add features.
