It seems to require a high performace graphics card.
We did a lot of optimization, it doesn't need a high graphics card. The minimum we suggest Nvidia GTX760 or AMD Radeon 7950
Minimum requirements are entry level gaming graphics card from 7 years ago. Not necessarily what I would refer to as high performance, today. Can pick up and equivalents or better card for less than $80 on the used market any day of the week.
