Hi Kristoffer,
Thank you for the comment and for being interested in this experience.
Speaking based on my own setup, you will need a PC with a 2080ti graphics card or a newer card with similar performance to get smooth gameplay, as you can see, the game has a lot of foliage assets and realistic lighting and that's why it can't run as a standalone game on the Quest only.
Please let me know if you have any questions.
Thank you.
