Not familiar with that book :/ Would you recommend it?
Sorry to hear your computer is having trouble, we're working on optimizing the game more.
I would absolutely recommend it, it's a science-fiction classic (Link). Though be warned that Stanislaw Lem is not light reading.
My computer is an 8 year old notebook with a Geforce GT 745M graphics chip - that's really low-spec, so I doubt you can really do much about it on your end. I managed to get the game running with a decent fps, so it's not too bad :)
