Quoting: GuestThat's probably this:
https://github.com/ValveSoftware/Fossilize

Not part of Vulkan itself, but one of Valve's tools to help Vulkan based programs load a bit faster, especially on the first boot. Basically that should go away eventually, once the cache is all built up, so I wouldn't worry about it.
Quoting: GuestIt did look like a hardware problem :).

About the CPU usage… Fossilize seems to be Steam’s tool to compile/store/share Vulkan shaders so it’s normal that it uses a lot of CPU, and you can disable it in Steam’s settings if you want (I keep it disabled because it wastes a lot of bandwidth and disk space… and CPU it seems).

When you run a game it’s quite normal that it uses a lot of CPU too. Going above 100% just means it’s using more than one core.
Oh so the CPU is fine then :grin:
If that is the case then i only need to find a way to use my keyboard again without having issues and everything will be fine! As using my father's keyboard solves all the movement issues.

China is famous for producing crappy non standard usb devices that only work on Windows.

They also make good keyboards, its a question of margins - ie. You get what you pay for
