I'm in the battle against the archon, but around 90% of times the game lags when I'm trying to evade him attacks, so he it me most of the times, quickly defeating death.

I'm found those combat lags more times in this game, but with this particular boss, the lags are effectively preventing me to defeat it.

Edit: Just after disabling the AA, I'm found that in the first stage of the battle the archon attacks make less damage, but in the middle of the second stage, him attacks start again to make massive damage, and in all of the next tries, he makes massive damage again from the very start. Definitely somewhat is really wrong with this game. I'm also cannot finish the Light of the Fallen sidequest due a glight with the counter, that is stucked at 9/10. Not to mention the Kartinos bug.
