I always thought I was the only one noticing this.
With Compositing enabled, both with DWM and on GNU/Linux, the whole interaction seems to become "soft" instead of the raw that feels much nicer and snappy. From my experience it also has to do with passing through the stack to the GPU when compositing, running it all from the CPU is what makes it feel snappy.
I've also been researching about removing the triple buffer vsync on W10. It seems it was possible in the first builds by replacing some system files, but that option is gone now with the recent big releases.
As of that, I do not see the real reason why compositing would be needed on W10, as transparency and etc arent important factors.
