Arena is a bit weird. Sometimes it feels like playing against the Shadow Legion Centurions from Prophesy of Pendor, that's how accurate the javelin throwers feel. Laser guided missiles straight to my head before I can even orient myself. It's still pretty fun though.
Also, why are Stances not covered in the tutorial section? They are a not-insignificant part of the combat system, I've heard, allowing you access to skill-based gameplay features such as chambering attacks, and yet they're not covered in the game's own tutorial. Why the disconnect there?
And yeah, I have 8GB ram and experience quite a few FPS problems with Bannerlord. Whereas I can play a game like PlanetSide 2, which is known to be poorly optimized, on Ultra graphics at a reasonably stable 30FPS even when population is upwards of hundreds playing at once in the same relative area. Maybe I'm not doing the comparison right, but it seems to me there is a big problem with optimization or some kind of memory leak present in the game. It seems weird that 8GB of RAM is not enough to play a game at a stable FPS even at lowest settings.
