When you use the Steam version of a benchmark, it submits your results to an account on 3dmark.com based on your Steam ID. You can sign in to your account on 3dmark.com by using the SIGN IN THROUGH STEAM option.
If you already have another 3dmark.com account, you can merge your Steam ID account into your existing 3dmark.com account.
An account created from a Steam ID can be converted into a fully-featured 3dmark.com account. All you need is to enter an email address and choose a password. You need a full 3dmark.com account if you want to participate in overclocking contests organised by us. Otherwise both account types work the same way. You do not have to give any personally identifiable information beyond your Steam ID if you don't want to.
