I noticed the following comment over on another forum…
"As I have mentioned previously, there is a lot of good low level changes in this release.
If everyone remembers, the development for this version started last year around this time, and was handed over to the Azure kernel team, and the original kernel designers of NT, like Dave Cutler, along with newer NT kernel specialist.
The NT kernel in this version got a LOT of optimization in this release. New features, faster, improved security, etc.
Things like a new faster threading model, which includes both CPU and GPUs - along with other processors that NT can directly manage.
The raw speed of the NT kernel is also significantly faster.
This also includes a bump in general speed on all low level CPU operations.
The CPU performance differences alone are around 24% faster on average on most CPUs. These results can also be seen in everyday workloads, along with direct testing in CPU centric tests like Cinebench20, blender, CPU-Z, etc.
So even if users don’t notice a ton of new features, this is a worthwhile upgrade, as there there are a ton of changes in lower levels with regard to speed and features.
PS Edit - As I noted in a response above, we are also seeing some impressive performance jumps in DX12 games."
