What I am noticing if you have the high-res patch on and the updated character models, the game slows down quite a bit. It can't really handle the enhanced graphics (the game engine can't) that is.
Eventually I keep getting random freezes within the game, and have to End Process from the Task Manager and restore the game.
I am currently, using the FF7 music, high res, and upgraded models.
I have a feeling it's got to be one or the other with this game, since the engine is so old it can't really handle it. Anyway to circumvent the consistent random crashes within the game, or freezes?
