It should come as little surprise in general but making use of Advanced Vector Extensions (AVX) for multimedia encode/decode is a big deal for performance. While one could hope that by 2020 most open-source encoders were already extensively utilizing AVX(2), that isn't yet the case with the latest being AOM-AV1 picking up another optimization...

Recently carrying out some benchmarks of all major kernel releases from Linux 5.0 through Linux 5.9 ended up yielding some surprising performance changes with the in-development 5.9 kernel. Here's details on this historical look at the kernel performance and what's going on with the Linux 5.9 kernel slowdowns.

Proposed last year were a set of patches aiming to improve the Intel virtual GPU "vGPU" performance in para-virtualized cases by having optimizations around the shared memory region between the guest and Intel GVTg code. With optimizing the workload PV submission and PPGTT PV updates, the glxgears performance could improve by 30~50% while for large media/3D workloads was more around a 4% average improvement...

When looking at the performance of Zink's OpenGL over Vulkan implementation just about one year ago the performance had a lot to be desired. But since then they have patches bringing it all the way to OpenGL 4.6 compared to the OpenGL 2.1 days and there has also been a lot of work on the performance. The performance at least for select operations is now turning out better than even the developers were expecting...

The V3DV open-source Vulkan driver being developed by consulting firm Igalia for the Raspberry Pi Foundation is nearing official support for Vulkan 1.0...

Proposed earlier this summer for GNOME's Mutter was the idea of triple buffering the desktop when the GPU is running behind in order to ideally cause that extra load to ramp up the GPU clock frequencies in order to in turn get back on track with rendering the desktop on-time. A third version of that work is now brewing albeit too late to see with the imminent GNOME 3.38.0 release...

While AV1 adoption is still taking off and finally seeing desktop hardware with AV1 decode, given the time it takes to develop a new high-end video codec it shouldn't come as too much surprise that "AV2" is already being explored...
