I just got this on the Mac and after playing single player for a few hours I am enjoying it immensely. Some bugs I've noticed, though:
- Red "projection" or silhouette of character models and horses on the sky during most night battles (as noted by other posters). I find that this more than any other graphics bugs kills the immersion
- Weird black boxes around grass, which I've accordingly turned off for the time being by setting the density to 0%
- Character models sometimes not rendering properly in menus, e.g. when setting up custom battles
- Banners are distorted/"garbled" as reported by others
- Can't rotate the world map with right mouse button
I have yet to see a rider go flying off the map, though I don't doubt I will at some point. I also haven't tried online play, so I can't say anything about that.
Any ideas when some of these might be fixed? I don't mind most of them, but many, especially the red silhouettes, can be quite distracting.
All in all, though, great game, looking forward to many hours to come. A big "thank you" to TaleWorlds for making a Mac version!
