Capcom is working on patches for the PC release of the fighter, fixing three major issues: unrecognized controllers, crashes caused by remapping controls, and the default "Smooth" mode, that drops frames for lag-free online play. The first two issues should be addressed by July 11, while the patch to make smooth mode no longer the default option is expected as a Title Update "on or before July 25."
In a more frivolous and costly update, Capcom also announced the release of costume packs for the "non-Steam" version today. Eight different packs are available at prices ranging from $4 to $6, or you can grab them all for $15. If you're playing through Steam, you'll have to wait until July 23.
