Getting it up and running was as simple as swapping my AMD RX580 for the Intel Arc A770. The drivers are open source and built into the kernel and Mesa. It picked up and started working without issues.

Its ran every game I have smoothly at max settings. I haven't had to turn down the graphics settings on a game yet. Though to be fair, the most graphic intensive game I play is No Man's Sky.

Only issue I encountered was when I first got it I had to tell No Man's Sky to use the Xe Vulkan support, instead of trying to use the old Intel HD version. Since then I've reinstalled No Man's Sky a few times. Newer updates properly detect the Vulkan support.

I was impressed enough with its performance that I bought a second to upgrade my wife's computer. She has been using that system to do modeling in Blender and hasn't had any issues with it that I've heard of.

I have been quite happy with the Intel Arc card. If they are still making them when I do my next upgrade I will likely get another.
