AOM AV1 Encoder Sees Big Boost With Additional AVX2 Optimization
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...
Linux 5.0 To Linux 5.9 Kernel Benchmarking Was A Bumpy Ride With New Regressions

New Intel Linux Graphics Driver Patches Aim For Better vGPU Performance
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...

Zink OpenGL-Over-Vulkan Driver - Performance Is Turning Out Better Than Expected
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...
