An anonymous reader writes from a report via Ars Technica: No Man's Sky, an indie "video game that promises 18 quintillion planets" from a "small development team," has launched today for Windows PC gamers via Steam or GOG. Unfortunately, the "worldwide simultaneous launch on all kinds of PCs" is off to a rocky start -- as evidenced by the "mostly negative" Steam reviews. Many gamers have complained about frame rate hitches and total system crashes. Ars Technica reports: "Even users with high-end solutions like the GTX 1080 or two GTX 980Ti cards in SLI mode are reporting major stutters -- on a game that runs on a comparatively so-so PS4 console with a mostly consistent 30 FPS refresh. The game's PC version defaults to a 30 FPS cap, which can be disabled in the normal options menus. But with this setting turned on, the game can't help but hitch down to an apparent 20 FPS on a regular basis, not to mention throw up frequent display hitches of half a second at a time. Removing that frame rate cap can get play up to a smooth 60 frames per second, and we enjoyed more consistent frame rates without the cap. But even those frame rates can bounce down to 30 or less at random intervals. The game also suffers from freezing hitches, even without apparent spikes in visible geometry like creatures or spaceships." Ars also mentions that the on-screen prompts don't update the button remapping accordingly. There's been some frustration among PC gamers who have had to learn the hard way that the game's floating-menu interface was built with joysticks in mind. Mouse scroll wheels don't seem to work to scroll through text and between menus, and players are required to hold-to-confirm every menu interaction in the game. What's more is that alt-tabbing out of the game is a "guaranteed crash." For those looking for more information about the game, The Atlantic has a captivating report describing the game as if it were like reading a book.
