It's a Cider "port". No real surprise…Edit:
Now that I have tried it for a short time, I must say it is terrible. I can´t believe they found it fit to be released.
Playing on bootcamp the game works splendidly on high settings, with the MAC version it is barely playable on standard settings. I expected some performance hit, but not a decrease of 30-40fps while using a lower resolution and standard setting. I just hope that SQEX will give an announcement that they will do something about this soon.
Yep. Each platform is a separate purchase, minus I think PS3/PS4? Think they made it easier for them tho.
PS3 and PS4 requires different licenses. They had for a limited time a campaign where you could switch your PS3 license for a PS4 license, lasted till April or Mars this year I believe. You can however transfer your crossbar settings whenever you want.
Which ultimately leads to the question why they ever thought a Cider "port" is a good idea, when they knew beforehand that the performance would be significantly worse.
...well, there was the recent Batman: Arkham Knight debacle that played out similarly.
