Netflix and GPU folding=lagging

Postby beer » Thu Apr 20, 2017 6:08 am

Hi

I am running Debian 9 with Firefox to watch Netflix, but every time I watch a movie while GPU folding then it becomes lagy. Is there any other option than to pause GPU folding when watching Netflix?

Not sure; but other recent posting a suggestion was to try to switch rendering/decoding to CPU and don't use the GPU. I just wouldn't know where those setting would be.

Netflix uses web browser html5 video.

This thread tells how to enable Firefox GPU hw acceleration, so use it to set the options to disable.

At the risk of sounding like an ass, how is this not obvious? Using massive amounts of your GPU makes watching HD videos laggy, and it should.

In advanced options of Firefox, un-click 'Use hardware acceleration when available'. This fixed the problem for me a long time ago.

But it is not so obvious that you can switch your web browser or video player from default GPU hw acceleration to CPU and how to. :egeek:

Nor is it obvious to everybody that your CPU can do a more than adequate job of rendering videos (or updating what you see on your screen like is happening right now as I type). Moreover, the CPU manages the priority for rendering MUCH more effectively that the GPU, so "hardware acceleration" falsely implies that it will be faster --- based on the false assumption that the GPU is "always idle."

I tried to switch of the hardware acceleration in Firefox but it did not help. Then I tried to install Google's Chrome and that solved the problem (without disableing anything)
