Although the game is by no means perfect at the moment (just saw the fps drop thread pop up again). However I have to say that for me the game has been better running that ever and is more enjoyable, so props to the developers! Keep up the good work and I have faith in the fact that you'll get the rest of the problems sorted as well.

Yes, being in the silent majority that's playing the game without major (technical) problems, I have to agree with OP.
The game has been running relatively smooth for me aswell. Only ONCE i had the flickering screen at the Crown and that went away after i died. FPS seems steady at 40-60 even in bigger fights and no crashes (surprisingly)... So they must be doing something right.
