Sorry, if it sounded harsher, than it should, but the gamezzzzz and the sloooowww... never mind.
It looks like you have the latest release of dolphin, 64bit aswell.
What for a cheat are you using? Normally a cheat won't slow down your games at all.
The only problem could be, that the cheat is spawning a lot objects, but I can't imagine such a cheatcode in RE.
i know this is an old thread but it seems like this guy's getting a bit of the cold shoulder thanks to a healthy dose of skepticism. i am using the newest version of dolphin for the newest mac os and im running it on an old intel core 2 duo running at around 3.2 ghz or so with 4 megs of ram. most games run at 100% with no settings tweaking with the exception of baldur's gate but one thing that all games have in common for dolphin is that for each code you enter and keep enabled, it slows down the game more and more. it doesnt matter what game. this obviously isnt an isolated incident in my case since i got confirmation from mr marcin2x4 here that its otherwise. also, no comments on the lack of punctuation or capitalization. dont like it, dont read it, dont respond. its your choice. thanks in advance to anyone who has answers.
