Valve’s PC gaming platform Steam continues to break records.

On Sunday, May 10, a record 9.5 million people were logged into Steam at the same time. That’s a new concurrent user number for the platform, and is up from 9 million just a couple months ago.

The news comes by way of Steam’s “Stats” page, which reveals that the milestone was achieved in the early afternoon PDT on May 10.

Valve’s free-to-play DOTA 2 is currently the most popular game on Steam, based on unique users, followed by Counter-Strike: Global Offensive and Grand Theft Auto V.

Steam is a juggernaut in the PC gaming space. It currently has more than 125 million registered accounts.

In other Valve-related news, the company recently found itself in some hot water over paid mods, while its new Vive VR headset–made through a partnership with HTC–will launch later this year.
