The Destiny 2 open beta on PC has come and gone, and the good news is that the game is looking good and running well.  When the PC version was revealed, Bungie promised it would be "legit on day one", and the general consensus is that they've delivered. Credit for that must go to the work done by the dedicated PC teams within Bungie and Vicarious Visions who worked on what is certain to become the definitive version, even if we do have to wait a little longer for it. 

I spent much of the first half of this week running benchmarks and I gave a preview of 4K performance requirements. Now, as promised, this is the full rundown of performance with the Destiny 2 beta. Obviously, with two months until the official launch on PC, there's plenty of time for things to change and improve, so this is merely an early taste. If you're planning on getting into the PC gaming scene with Destiny 2, it's also a guide for the hardware you'll want to buy, depending on your intended resolution and performance.
