Dennis Gustafsson is currently working on a project/game that will leave you speechless with its advanced physics. This game, which currently does not have a title yet, may soon enter its early access phase, and you should unquestionably keep your eye on it.
According to the creator, the game currently runs with 60fps on a GTX1070 and quad-core machine.
I'll definitely let you know when the game hits Steam Early Access so stay tuned for more!
