The first few sessions were very laggy. Now it's somewhat good. Some part of the UI still takes very long time for response and loading. But I am able to do my regular day to day tasks without any problem.
For some reason Blur/Transparency Effects doesn't seem to work on my PC. It just shows solid colours in the Taskbar and rest of the UI. It didn't work on Windows 10 either. Even apps like TranslucentTB doesn't seem to work.
