God of War III [BCES00510]

i just have finished this game already! Ryen 5 3600 the FPS should be around 15. most notables problem:
1. the glitch : so you have to keep on restarting the autosave and test your luck to trigger the cutscene or to jump into the ledge
2. the smashing button : to kill the medusa snake, you need to smashing button 'O' and if you do it too fast (strangely) it will failed
3. the last part of Autosave (the labyrinth), i suggest you copy and paste the folder of AUTOSAVE manually (read no 4 below) just after Kratos fall down into the black water, or your last Autosave game will have a glitch of noone on your screen fighting, but you can hear them in the background.
4. the final confrontation with Zeus you need to smashing the 'O' button also, but this time, after you press it like hundreds of times and the games doesnt trigger the ending video, you need to mashing all button, eventually it will trigger the video.
