its realy wierd tho, ive played this game on a laptop too and i never had slowdowns whatsoever, also european version...
(i7 2670qm turbo 3.1 on pcsx2 2.8ghz, yours should be around the same value)
gt555m <<weaker gpu
first off drop that internal resolution to 2x not more not less. just stay on 2x as long till you get full speed allround, i know its possible and find it strange that you dont get it :/
could you post the following settings for me?
gsdx settings (2x native!) << if any hardware hacks are enabled disable them (pretty sure you didnt have it checked in the previous page but still better safe then sorry
)
gs settings (emulation settings)
speedhacks settings
gamefix settings
can help you in about 8 hours or so, pretty late here xD so forgive me if i am going to respond quite late
but if i am correct its also late at your place, france and netherlands arent that far off xD
bookmarking this btw, so that i can react in the topic when i wake up
