While we will do our best to make sure Destiny 2 is available on the widest variety of PC hardware, we do not officially support Destiny 2 PC on laptop configurations. Laptops with specifications that match or exceed our Minimum System Requirements may be able to play Destiny 2 PC.
Although I cannot give you definitive numbers, before a fair few months ago my gaming took place on laptop iGPU’s for the majority of my life.
A rough estimate I’d reckon is 1080p Low Settings you’d get anywhere between 25-35 fps. There are many contributing factors that play a part in performance. I may be wrong and perhaps you could get a 60fps performance, I haven’t had the chance to play around with anything better than the old Intel UHD And Ryzen Vega integrated graphics.
I don’t see why you wouldn’t get solid 720p performance though, maybe up the sharpening a tad tho.
Happy to help test though when I get my laptop, Im not an enthusiast at the game but I got a free copy some time back.
