Capcom has posted up a few new details on the upcoming PC version of Street Fighter IV. The game will have Games for Windows Live support built-in, meaning it'll come with voice chat, achievements, and the other stuff that being GFWL-compliant provides. In addition to the obvious PC benefit of running in a higher resolution (provided your hardware can handle it), the game will also offer support for multiple shaders. This will offer a few different light tweaks to the graphical style.
The shaders are referred to as Watercolor, Poster, and Sumi-e Ink. The ink style looks like it throws a lot of ink splotches around the edges of the character models, sort of like those early trailers and the game's focus attack animations. I always thought the game could have used more of that. Here's a shot filtered through Sumi-e Ink:
It'll be interesting to see how the PC version of the game does. I don't really think people identify the PC as a fighting game friendly platform, but then there are already people out there playing arcade versions of stuff like Street Fighter III: 3rd Strike and Tekken Tag Tournament on their PCs in a not-quite-legal manner. So maybe there's enough of a base out there for something like this to be really big?
