Please restart the Steam client to download the latest build.

We’ve discovered that some reports of performance issues were actually caused by the game’s Auto-Detect system creating bad default settings for players. So, we will be overhauling our Auto-Detect system.

Because Auto-Detect was establishing bad settings, we have to reset all players’ graphics to base settings when this version is first run. You’re free to change these settings afterward.

Additionally, please know that we’re also cranking on many more performance improvements across the game.
