While playing one of the best RPG of nowadays The Witcher 2: Assassins of Kings (version 2.1) I’ve hit an interesting issue.
I was fighting the Kayran and chopped of all smaller tentacles, but when I’ve jumped on the big tentacle and the QTE has started (that part where you need to push button fast to climb) and when the bar was full, I’ve expected the bridge to come down, but nothing happened. I’ve fallen down anyway. I had to do the whole exercise over again and again.
This note in forum helped me to find the root cause. It looks like to be a bug – a frame rate issue. After lowering resolution to 1024×768 everything worked smooth.
NOTE: Your game resolution, not your monitor resolution.
