After refreshing my laptop and installing 8.1 (several times because some things would constantly fail for some reason), I discovered that my computer is listed as a tablet.
Also, after the 8.1 install, games have been running really weird aswell. For example, League of Legends would max out at around 35 FPS on AMD Radeon R9 M270X (AMD Radeon HD 8870M before driver update).
If you go on a UA string analyzer (such as http://user-agent-string.info/) and click "Analyze my UA", what kind of device does it tell you that you are using?
