Hi MelanieFS,
Sorry to hear you are having performance issues. We are working on improving performance where we can as many of the environmental effects are quite graphics and CPU intensive. We will do our best to make the game as performant as possible and we hope you will get the chance to play it without any hickups in the future.
Also a big thank you for notifying us about motion blur. We will make sure to add an option to enable/disable it as soon as possible! We understand that it's something many players don't like. It sometimes happens that we overlook simple things like that and we greatly appreciate when you bring them to our attention.
/Alfred
