I wanted to buy Planet Coaster because it is currently on sale. But now I first wanted to know if it is even on my HP ProBook 6570b I know, which is specified what is needed, but I know with processors etc not schonmal thanks in advance.
I could not figure out much about the hardware would be helpful if you call your GPU but the rest looks awful already
Planet Coaster needs a lot of power and only runs on reasonably current gaming PCs.
What do you mean with GPU and how does it look lousy?
CPU is slow and as I have seen only 4gb ram in the graphics card, I do not expect much
That will not work. According to the specification (see: https://support.hp.com/...c03370081) your laptop is too weak. In addition, laptops are generally not suitable for gaming.
You can buy and test the game on Steam. If it does not run smoothly, then just give it back.
