Technical defects

First problem: game in normal graphics settings runs in slow motion, so jerky permanently. Then shut down settings, the graphics are still very colorful and it develops an atmospherically dense game, with a fairly high level of difficulty, when asked on normal difficulty.
At the first final boss (Kayran) then the flop: First difficult opponent nrauchte to create a tight day at the Hauptkampft, it does not create QTE-, after half a week and internet research the solution: Graphics settings throughout runterregeln- now can the font no longer read, but good is only for the fight. After successfully fighting the crashes unfortunately program still on! I gebs now off-pity!
