Graphics: 2 GB Video Memory†, Shader Model 5.0.many ready-made space systems for the test, from the destruction of the Earth by the moon to the connection of two galaxies.a huge number of small settings for each object.many real-life space objects, from spacecraft to galaxies.we believe this sandbox will definitely increase the fun and promise after adding this feature. There is no change at all, so we hope to add the function of evolution, that is, stars will enter different stages over time, stars-main sequence stars-red giants-red supergiants-supernovas, and stars in different stages will give some of the surrounding stars Other planets bring different effects. As a result, hundreds of millions of years have passed. Then we put a star there and adjusted the time step faster. we originally wanted to observe the evolution of stars. This sandbox is good, but we found that it has a shortcoming.
