Open-Source Raspberry Pi Graphics Drivers Add Double Buffer Mode

[DebianLinuxero]

I have a Raspberry PI 4b 4GB.

I thought it was a good idea but graphics performance in 64 bit mode is disappointing.

How could it be that any aged, entry level, Intel or AMD processor (10 years) with integrated graphics, outperforms it in simple tasks like running GNOME or KDE desktop compositor effects, or video playing, when the Raspberry has supposedly more modern graphics hardware?

I don't talk about games. I talk about simple desktop use.

And I don't understand how this machine was announced as capable of 4K video playback.

Phoronix: Open-Source Raspberry Pi Graphics Drivers Add Double Buffer Mode

Mesa's V3D and V3DV drivers providing open-source OpenGL and Vulkan driver support, respectively, for newer Broadcom VideoCore hardware now has a double buffer mode implemented. This is a win for numerous workloads for these drivers most notably used by modern Raspberry Pi single board computers...
