I find Edge freezes a lot. Pinned sites weren't giving live tiles, but all of a sudden they are.
There is no Graphical tearing, I would update your graphic card drivers. Nvidia has released official ones.
If you check Windows update a new Direct X 12 update comes through. My games seem to be running great at full settings. Tested Metro Last Light as well as Skyrim heavily modded. Honestly, it almost seems like it looks better. I know they said Direct X 12 will make existing games take advantage even if the developers didn't use the API. It's hard to compare without side by side though. Could be a placebo effect from knowing DX12 is installed.
Speed of the OS is great. The only problem seems to be Edge. Edge can't handle sites with a lot of ads. And well I forgot the internet had Ads because I used adblock for so long haha. God the internet sucks with Ads.
