ORIGINAL STORY 21ST OCTOBER: Next month you can move Dark Souls alongside its saves and achievements from Games for Windows Live to Steam, Bandai Namco has announced.
You can redeem your Games for Windows Live Tokens on Steam to get From Software's wonderful action role-playing adventure at no extra cost.
At some point in November there will be a window during which you can transfer your save data and achievements over to your Steam account. Games for Windows Live Rankings will not transfer, though.
There was some concern last year that Dark Souls' online modes would be sunsetted on PC as the game was limited to Games for Windows Live, which was slated to be shut down last July. Despite this, Microsoft was adamant that it would continue to support its PC games online.
On PC Dark Souls is known as Dark Souls: Prepare to Die Edition, and was released in October 2012 with new content. It was criticised for being a shoddy port of the console versions. Eventually, however, PC modder Durante issued a fix to enable display at 60fps, an improvement on the standard 30fps. To run the mod you'll need the original "Durante DSFix" mod first, which removes the the game's 1024x720 rendering resolution limit.
Japanese developer From Software had admitted having a "tough time" with the PC port, something it blamed on the studio's inexperience with the platform.
"We wanted to get the PC version out as soon as possible, it's more strictly a port from the console version. We haven't been able to step up into doing any specific optimisation for PC."
Rich Stanton awarded it 9/10 in Eurogamer's Dark Souls: Prepare to Die Edition review, saying: "Dark Souls: Prepare to Die Edition does not come with the technical options you would expect from a well-engineered PC game, because it's a port of a console game, and that's all From Software ever promised to deliver. Anyone who passes up Dark Souls for this reason is cutting off their nose to spite their neckbeard of a face."
