Hier hat er ja das nochmal auf Crymod gesagt:

Well, its partly the map because it hasnt been optimized, there is a LOT of things going on that should be switched off by FG to save performance (AI, particles), hardly any occluders etc thats why I said the whole thing would need re-working, and I dont have time. Did you read the post with the download link in? As I said there its unfininished and I thought I may aswell just release it rather than bin it.. Thats why there are no objectives.
