NOTE: I just downloaded the game and on my first attempted launch, it complained that the port it wanted was not open. My only option was to close the game. I ran netstat and did not see the port listed, so I tried again. THAT time, it complained about my older video card :-/ The warning is clunky and there’s a typo, too (within -> withing). It says (if I transcribed accurately):
You are using an: NVIDIA GEOFORCE GTX 1080. This video card is currently not recognized withing the recommended specs. We only support a limited amount of NVIDIA GTX graphics cards, all NVIDIA RTX graphics cards or all AMD RX graphics cards since the local AI requires a lot of performance.
So please note that the game might not work properly. Refer to the Steam guide for more information.
