Maximum PC has a report on an event where Valve unveiled new features
planned for an upcoming
Steam update, including automatic driver updates for
hardware and an integrated system requirements checker for games. Here's a bit
on the Steam Cloud:
Community enhancements include improved event
planning – RSVP, calendar functions, and official communities are all part of
the feature list. Gamers will be able to coordinate tournaments, use calendars
to check up on their friends, and join communities set up by game publishers and
developers.
The biggest news is that game-generated data will now be stored with your Steam
accounts in Valve servers. This includes game profiles, configuration settings,
and even savegames! Valve will first be rolling this feature out to existing
games like the Half-Life franchise, TF2, Counter-Strike. Left4Dead will be the
first new game to remotely save your progress.
