The game is pretty heavy on memory usage. With 16 GB RAM, it uses about 35% of my machine´s memory while running it in pretty heavily modified "court" with 6 characters + OP. My guess is that the bare minimum to run the game somewhat would therefore be 8 GB RAM. On my laptop, I cant run the game at all as that one is just a regular one for work. I dont believe the game is especially demanding on other resources. My recommendation to try to play it is to turn off various "unnecessary" programs that run in the background if you have not yet, and try to run it with low graphic settings. Also make sure that your graphic drivers are up-to-date. But, if your PC has less then 8 GB RAM, I dont think it will be playable unless its optimized more. But I should also add that I am total layman when it comes to computer specs.
