Am i supposed to open a specific file?

When starting the game an error appears: "The cpu does not support a required functions". Can I somehow launch the game? she looks great, I'd love to check it out

If I say, alt-tab out of the game, it will run at uncapped framerate for me (i suspect), so GPU will sound like a jet engine. There were some parts of the game that also had this issue but only in specific parts. I am not 100% sure if that is the case, but I have seen other devs fix this exact issue by adding vsync/frame cap. I do have frame cap set for all applications but I suspect this game overrides it in some spots or when I alt-tab....
