What GPU and CPU?

Ivoah commented 9 years ago

GPU: Intel HD Graphics 3000 CPU: Intel Core i5

8GB of RAM

phiresky commented 9 years ago

Sorry man, but it's not gonna get very far with an Intel 3000. I tried on an Intel 4600, and it still is extremely slow. I don't think it has anything to do with the OS.

Bummer :( Why does it need such a good GPU? Other games/programs run fine

phiresky commented 9 years ago

Because basically everything is done on the GPU. Every screen pixel has a ray that is traced into the space individually untill it collides with something. It's a very different technique from traditional games and very expensive.

Maybe the shaders can be optimized further, but I think @cnlohr has to look into that.

Hmm, okay.
