Most laptops, even high-end ones, don't include dedicated Nvidia or AMD graphics hardware, unless they're intended for gaming or creative work. The lowest-end compatible Nvidia GeForce 660 GPU is about 10 years old at this point, and technically it's still faster than the best integrated Intel Iris Xe graphics, although only by a little. On the same Dell, I was able to download and play Diablo 3 on it perfectly fine. The game would simply pop up an error message when I tried to launch it. But a Dell XPS 13 with an Intel Core i7-1065G7 and Intel integrated Iris Plus graphics was a no-go. Also great was a gaming laptop with an Intel Core i7-8750 and a Nvidia 2080 Max-Q GPU. On a desktop with an Intel Core i7-6700 and a single Nvidia 1080 GPU, it ran great, even at 4K resolution (yes, it was hooked up to my TV). In most cases, it'll simply refuse to launch, as noted by many beta testers in the game's beta forums. The game does not support even Intel's better Iris GPUs. You're also out of luck if you're trying to play on a laptop without a dedicated Nvidia or AMD graphics card. That's too bad, because I think this game would have been perfect for a 24-inch iMac, and I've been able to play games like Baldur's Gate 3 and Hades perfectly fine on an M1 MacBook Air. If you're looking to try the old 2000-era game on your Mac, Blizzard has instructions here. Even though the original Diablo II was popular on Macs for many years, the new version is PC-only (plus Xbox, PlayStation and Switch, of course). Note there are no system specs listed for Macs.

Holy point shot diablo 3
