The other difference you mentioned…you’re now using wireless. If feasible and as an experiment, what about temporarily setting up your gaming gear close to your router and using wired to eliminate the wired versus wireless variable?
It started a couple of days ago when I moved. I'm actually noticing a delay when I kill enemies as the host and it's like all enemies do triple damage and have super increased accuracy.
It's possible your PS3 has become self-aware. Perhaps the AI is learning and adapting each time you play. Since you moved, have any networked appliances in your new home tried to kill you?
Just to be safe, I'd bury an axe in your PS3 posthaste.I enjoy your posts on the forum and would hate to see you killed off by sentient machines. But then I've always been a bit of a worrywart. Good luck.
