Hey, so minimum Mac spec (based on what we developed on...) is 2015 2.7 GHz i5 Mac; 8 GB RAM; Intel Iris graphics card; 64-Bit OS. Runs a bit slow at times, even on modest graphics settings. We're working on optimizing it for this level of a machine.
Minimum Windows spec is unknown, I know it runs on 64-bit Windows 10. We got all our footage at Max settings on a mid-spec VR-ready machine - Intel i5 6500 3.2 GHz, 16 GB RAM, GeForce GTX 1070.
If you can/can't get it to run, please let me know so we can update the page with more detailed info. Many thanks!
