When I played Destiny 2 last month, the most striking difference wasn't anything about the game itself. It was how it felt to play it on PC.
Today NVIDIA posted a video that shows what the game looks like on PC in 4K resolution, running at 60fps. This won't be of interest to anyone but the hardest core Destiny-heads, but it does give a sense of what the game looks like at a higher frame-rate.
Destiny 2 hits PC on October 24, more than a month after the console versions launch on September 6. The PC beta is also later than consoles, coming some time in August.
