Hardware acceleration of Chrome's Flash plugin

Running Flash in Google Chrome drains my CPU massively:

I figured that the cause of this issue would be that hardware acceleration of flash is turned off. When I tried turning it by right clicking a flash application and selecting settings, this window popped up:

No hardware acceleration options can be found.

In Chrome, when I open about:gpu, I get to see this:

How do I turn hardware acceleration on in Flash or is there an alternative way of reducing the CPU usage?

You should check your about:gpu section in Chrome/ium. In older PC's HW Acceleration is disabled by default and you only can enable it by overriding the settings in the about:flags.

• Open the about:flags in your address bar
• Look for Override software redendering list
• Click "Enable"
• Restart Chrome/ium

You can also start chrome using chrome --ignore-gpu-blacklist but having to do so each time is not ideal.

Try LIBGL_DRI3_DISABLE=1 google-chrome --ignore-gpu-blacklist if you end up here looking for a solution on a version affected by a LibGL DRI bug on Linux.
