That’s quite unprecedented as betas usually have limited graphical settings available.
Interestingly, the PC beta (and the full game) will support full 4K (at 60fps), uncapped framerates, a full suite of adjustable graphics settings, full keyboard and mouse support, and 21:9 monitor support. The PC Beta kicks off August 28 for Early Access, and runs August 29 through August 31 for the Open Beta.
Activision is kicking off their Destiny 2 PC Beta ahead of the October 24 PC release of their eagerly anticipated multiplayer first-person shooter.
