The most recent Steam Hardware Survey (http://www.steampowered.com/status/survey.html) shows more Steam gamers play on NVIDIA GeForce hardware than any other graphics platform. In an effort to further support this popular PC gaming configuration - Steam games plus NVIDIA hardware - Valve and NVIDIA have entered into an agreement to collaborate on development, distribution, events, and more.

Effective immediately, all NVIDIA gamers may receive a free copy of Portal: First Slice, a special version of the award-winning new game from Valve, by visiting www.steamgames.com/nvidia1 and "Taking the test." Steam will then auto-detect the presence of NVIDIA hardware and make Portal: First Slice available immediately, free of charge. To make it easy for all NVIDIA customers to redeem this offer, a link to the Steam offer will also be included in all NVIDIA drivers.
