If you have 8GB of RAM and a OpenGL core profile version string: 4.5 I am sure you can run the game on Ultra. I haven't experimented yet to find the minimum.

I was able to run this game on minimal graphic on my asus chi t300 [spec here: https://www.asus.com/au/2-in-1-PCs/ASUS_Transformer_Book_T300_Chi/specifications/  ]

only good for 1v1 or max 2v2 though

 more than 300 units at a time would crash you for sure

ZK uses the SpringRTS engine which has requirements listed here: https://springrts.com/wiki/About

You can assume ZK has similar, if not stricter requirements.
