Im gonna play some dark souls 2 Time to chill with some good single player games instead of getting headache from SOE and PS2

I'm not sure, maybe it is just a placebo and it's just totally random. I've noticed it comes on straight away if i get inside a Valkyrie, but not at the warp gate, only when going near a fight in some other hex. I've also seen it in tech labs, don't think there were any Valkyrie's present.

I am pretty sure that's it. All those reg cleaner do is delete empty folders and such. Deleting cache and temp files as well as defrag (on a HDD), can have performance benefits, but its barely noticeable, let alone in the game (loading times on a HDD excluded). Everything PS2 needs, it will install (or show an error code if it cant access it), and what it doesn't need, it wont touch. Its definitely something in the program code of the game.
