I have an exhibition coming up in an art gallery that I wish to exhibit a game that I made in Unreal Engine 4, but I am reluctant to buy a laptop just for running this game. Is there any other cheaper way of running Unreal Engine in this context ? All I need is a machine that can run a UE4-21 project and that has a USB input , for controller, and HDMI output. The project is a 3D game but it dosent have any crazy ray tracing or HiRes textures I have looked into a raspberry Pi 4 but its specs just arent there yet.
Any ideas or advice would be greatly appreciated
